Sanchi Topes

(300) dakshina, and the "left/' vcima. The west was called apara, "behind." Now Sariputra and Maha Mogalana were the principal followers of Buddha, and were usually styled his right and left hand disciples. Their ashes thus preserved after death the same positions to the right and left of Buddha which they had themselves occupied in life. 14.Sariputra was the son of the Brahman Tishya, and of the beautiful-eyed Sari or Sarika, who received her name from the resemblance of her eyes to those of a Saras or Cyrus bird. Sariputra, or son of Sari, is his most common name ; but he is also known by the patronymic of Upatishya. The Tibetans call him Sha-ri-hi-bu, or Sari's son. Tishya was the most learned of all the Brahmans at the court of Raja- griha. Sarika herself was a proficient in the four Vedas, and had overcome her brother in disputation. But her son excelled them both; and was much celebrated for his wisdom. His talents, which were attributed to his moral and religious merit in former births,* were so great, that Sakya himself proclaimed! that the " profoundly wise Sariputra was competent to spread abroad the wisdom of Buddha;" and his fellow-disciple Kachhayano declared that a excepting the Saviour of the world, there are no others in exist- tence whose wisdom is equal to one sixteenth part of the profundity of Sariputra."
(301) 15. According1 to the Japanese chronology, this wisest of the disciples of Buddha embraced a monastic life, four years after Sakya's attainment of Buddha- hood, that is in 584 B. c. He, and his fellow-student Maudgalyayana, had attended all the philosophical schools of the day without obtaining conviction, until they heard the preaching of Buddha, when they gave up all and followed him.
16.In a Mongolian wort translated from the Sanskrit, and entitled Uligerun dala'i (the Sea of Parables), we read,* " When Sabiputba learnt that Buddha was bent on entering nirvana, he experienced profound sorrow, and said to himself, f It is soon indeed, and contrary to all expectation, that the Tathagata hath resolved upon entering nirvana j who after him will be the protector and shield of souls and of beings enveloped in darkness V He then said to Buddha, 'It is impossible for me to witness the nirvana of Buddha.' Thrice he repeated these words, when Buddha replied, ' If thou believe thy time come, then do thy will, like all the Khutukhtu (in Sanskrit, Nirmmanhaya, incarnations), who enter the Nirvana of tranquillity/ Sariputra, having heard these words of Buddha, arranged his dress ; and, having a hundred times walked round Buddha, he repeated a great number of verses in praise of him. He then embraced the feet of the latter, placed them thrice upon his head, and joining the palms of his hands, said, ' I have been found worthy to ap-
(302) proach the gloriously accomplished Buddha/ He then worshipped Buddha, and proceeded with his servant^ the monk Yontij to Rajagriha, his native town. When arrived there, he said to Yonti, fGo into the town, into the suburbs, and to the palace of the king1, and to the houses of the high functionaries, and of such as give alms, and thus say to them: "The Kutukhtu Sariputra hath resolved upon en- tering nirvana— ^come and prostrate yourselves before him.'" The monk Yonti executed the orders of his master, went to the places indicated, and thus de- livered his message: ' The Kutukhtu SaripIjtRA hath arrived here ) if you Would visit him^ come with- out delay.' When the king Ajatasatra^ the dis- penser of alms, the great dignitaries, the officers of the army, and the heads of families, heard this an- nouncement, they were all filled With sorrow^ and with heavy hearts said, { Ah ! what will become of us when the second head of the law, the leadef of so many beings, the Kutukhtu SaRiputha shall have entered nirvana! Hurriedly they proceeded towards him, bowing down and saying, ' Kutukhtu! if thou becomest nirvana who shall be our protector,- and that of so many other beings?' Sariputra then addressed them the following words : ' Since all is perishable, the end of all is death. As ye, too, belong to this world of torment, ye, too, will ndt remain long; death Will come and terminate your career. But as you all, in consequence of meritorious works in a former existence, have had the happiness (303) of being; ton in tile World with Buddha, and that too in the human form, do you add other accumulative merits, and accomplish such works as Shall save you from Sansara.' When Sariputra had finished preaching thus to the bystanders the inexhaustible law, and had comforted their spirits with salutary medicaments, they bowed doWn before the Rutukhtu, and each returned to his home. After midnight, SaripuTUA sat in a perfectly erect position ; gathered all the faculties of his soul \ directed these upon one pointj and entered the first Dhytina. Thence he entered the second ; thence the third ; and from the third the four th* From the fourth he passed into the Saniddhi of the births of boundless celestial space ; then into the Samtidhi of the births of complete nihility. From this Samddhi he entered that of 1 neither thinking, nor not thinking f then into that of limitation ; and lastly into Nirvana.
17."When Khourmousda, the king of the Gods, learnt of the Nirvdna of SariPTjtra, he came with several hundreds of thousands in his suite, bearing flowers^ perfumes, and other objects meet for sacrifice. They diffused themselves through the whole space of heaven ) their tears fell like rain ; they scattered their flowers so as to cover the earth, saying, ' Oh ! he whose wisdom was as the depth of the sea, who had passed through all the gates of knowledge, whose musical speech flowed sweetly as a running stream, who was perfect in the fulfilment of every duty, in self contemplation, in all wisdom— the sublime chief of
(304) the doctrine, the excellent Khutulthtu Sariputra — hath too hastily entered nirvana. Who shall suc- ceed the gloriously accomplished Buddha and Tatha- gata to spread ahroad the law?' All the inhabitants of the town and neighbourhood, as soon as they were apprised of the nirvana of Sariputra, came, bearing- much oil, perfumes, flowers, and other things appro- priate for sacrifice. They wept loudly with accents of woe and sorrow, placing upon the ground the objects fit for the sacrifices. Khourmousda, the prince of the Gods, then commanded Vishwamitra to prepare a car of various precious materials for the body of Sariputra. When the car was finished, the corpse of Sariputra was placed thereon in a sitting position, and taken forth to a beautiful plain, all the while the JNagas, the Yakshas, the king, the commanders of the army, the officers, and the whole people, uttering cries of sorrow. There they raised a pile of chandana (sandal) wood. After moistening it with oil and butter, they placed upon it the body of Sariputra, and applied fire. Then all bowed down, and each went to his home. When the fire was completely extinguished, the priest Yonti collected from the ashes the sdrira of his master, and conveyed them, as well as his pot and ecclesiastical dress, to Buddha. He placed these things at the feet of Buddha, announcing, at the same time, the death of his master. When Ananda learnt this from the lips of Yonti, he was much grieved, and said to Buddha, 1 Oh, Buddha ! the first of our band has entered
(305) nirvana; to whom now shall we unbosom ourselves, and whom shall we regard as our protecting- sun?' Buddha replied, e Ananda ! although Sariputra hath entered nirvana, neither the charge of your duties, nor samddhi, nor understandings nor plenary redemption, nor the prajna of plenary redemption, nor the nature of occult properties, hath become so ; moreover, many generations ago Sariputra once be- came nirvana, because he could not endure to see me enter upon nirvana.' "
18.As the funeral pile was formed of chandana, or sandal, it seems highly probable that the two pieces of this fragrant wood, which we found along with Sariputra's relics, must have been taken from the pile. We know that a Tope was built over the charcoal with which Buddha's body was burned, and that the Moriyans of Pipphaliwano celebrated a fes- tival* in honour of their much-prized acquisition. From this account there would seem to be nothing improbable in supposing that fragments of sandal- wood from the funeral pyre of Sariputra should have been held in almost equal estimation.
19.Mogalana, or Maha Mogalana as he was usually called to distinguish him from others of the same name, was the son of the Brahman Mudgala. His proper name was Kalika or Kolita, but he was generally called by his patronymic Maudgal- yayana, or Mogalana. Csoma de Korosf calls
(306) him Mongalyana, that is one of Mongol extraction ; but his true Sanskrit name is Maudgalyayana.
20.The relics of these two famous disciples of Buddha would appear to have been almost as widely- scattered as those of Buddha himself : for we found another portion of their relics enshrined together in No. 2 Tope at Satdhara. We learn also from Fa Hian that at Mathura* there were Topes both of She-li-foe (or Sariputra) and of Mou-lian (or Mo- galana), while we know that the former died at Raja- griha, where a Tope was erected over his ashes which was still standing in 400 A. D. 21.It is not possible to fix the date of this Tope, more nearly than between 550 and 250 B. c. Sari- putra died a few years beforef Sakya's attainment of nirvana, in 543 b. o. It is therefore just possible that the Tope may have been built as early as 550 B. c. ; and if there was any proof that Buddhism had extended so far at this early period, I should have no hesitation in ascribing the Tope to the middle of the sixth century before our era. In the Tibetan Duha£ it is recorded that Katyayana, and five hundred other monks, were despatched by Sakya to convert the King of Ujain to Buddhism. This would seem to show that the religion of Sakya had been estab- lished as far as Ujain, even during his lifetime ; and that the omission of Ujain amongst the names of the
(307) celebrated cities which had witnessed various acts in the life of Buddha, is to be accounted for by the fact that the people of Ujain were converted by Katya- yana the disciple of Buddha, and were never visited by the Great Teacher himself. At the time of the Second Synod, in b. c. 443, the fraternity of Avanti (or Ujain) furnished no less than eighty orthodox Bhikshus to assist the holy Yaso in suppressing- the schisms of the community of Vaisali. As conversion must have preceded the establishment of fraternities and monasteries, the propagation of Buddhism throughout Ujain may be dated with certainty in 500 B. c, and with probability even as high as 550 B. c, during the lifetime of Sakya.
22.On the other hand, it seems to me more likely that the relics of Sariputra were all deposited in the Tope at Rajagriha ; and that they remained there undisturbed until the time of Asoka ; who, when he distributed the relics of Buddha over India, would most probably have done the same with the relics of Sariputra and of Maha Mogalana. I have already stated that the still existing gateway of this Tope is of the same date as those of the Great Tope, that is, the early part of the first century of our era. The railing I attribute to the age of Asoka, at which period I suppose it probable that this Tope was built, although it is quite possible that it may date as early as the middle of the sixth century before our era. The great Topes at Sanchi and at Satdhara were built principally of brick : and these I presume to beV (308) the oldest of the Bhilsa Topes, most of the others, which are of stone, were certainly of the age of Asoka.
(309) CHAPTER XXII. SONARI TOPES.
1.The little village of Sonari is situated on a low- spur of a sandstone hill, between the Betwa and Besali Rivers, six miles to the south-west of Sanchi, and about twenty-one miles to the north-east of Bhupal. The name is only the spoken form of Suvarnari, or the " golden wheel/' which is a symbol of Buddha as the Maha Chakravartti Baja. The traditions of the Buddhists say that when the age of man attains four thousand years, there appears a Xing of the Golden Wheel * " who is born in a royal family, and obtains supreme dignity on succeeding his father and being* baptized in the water of the four oceans. For fifteen days he bathes in perfumed water, and fasts- then ascends an elevated tower, surrounded by his minis- ters and courtiers. Suddenly there appears a golden wheel in the east, shedding a brilliant light, and advancing to the place where the King is standing. If the King would proceed towards the East, the
(310) 310 THE BHILSA TOPES.
wheel turns in that direction, and the King, accom- panied by his troops, follows. Before the wheel are four genii, who serve as guides. Wherever it stops, there does the King in like manner. The same thing takes place in the direction of the south, the west, and the north — wherever the wheel leads, the King follows; and where it halts, he does the same. In the four continents he directs the people to follow the ten right ways, that is to say, not to kill, not to steal, not to commit adultery, not to lie, not to be double tongued, not to calumniate, not to speak with elaborate refinement, not to abandon one's-self to lusts, not to entertain anger and hatred, and not to have immodest looks. He is called the King of the Golden Wheel, or the Holy King turning the wheel ; and he possesses the seven precious things, of which the first is ' the treasure of the Golden Wheel.' " This wheel has a thousand rays. The monarch who possesses it is called u the Holy King who causes the wheel to turn," because from the moment of his possessing it, the wheel turns and traverses the universe, according to the thoughts of the King. Other wheels of silver, copper, and iron, are also mentioned j but they are all nearly the same symbols of Buddha.
2.From this explanation of the name, it seems probable that Sonari once possessed a golden wheel, which must have been elevated on a pillar, as shownin so many of the Sanchi bas-reliefs. A pillar of this kind is described by Fa Hian, as still standing at (311) Shewei or Sravasti in Gudh, when he visited the place in 400 A. D.
"There are” says he, " two pavilions and two stone pillars on the pillar to the left, is executed the figure of a wheel - on that to the right is placed the figure of an ox." There is; however, no trace of a pillar now at Sonari; but the polished cylindrical shafts of these columns could be so readily converted into sugar-mills, that their entire disappearance offers no proof of their non-existence.
3.The Sonari Topes are situated on the top of the hill, about one mile to the south of the village.* To the north, east, and south of the Topes, the hill extends for some distance almost level, but to the westward it is broken into narrow ravines, which give rise to clear springs that once furnished the fraternity of Sonari with drinking water. The hill is covered with trees and low thorny jungul and the place is now as wild and desolate as it was once cheerful and flourishing when the hymn of praise was chanted by several thousand voices.
4.The Great Tope at Sonari is situated in the midst of a square court, 240 feet each side. In the southwest corner there is a solid square mass of masonry, from 12 to 15 feet in height, and 36 feet on each side. In the northeast corner there is a flight of steps, 4^ feet wide, leading to the top. The object of this building and of similar structures at Satdhara puzzled me very much, until I had seen the ruins at (312) Bhojpur, amongst which there is a very large building of the same description, but in a more perfect state. As this was undoubtedly a temple, I presume that the Sonari structure was only the basement or terrace of a Buddhist temple.
5.The Tope itself* is a solid hemisphere, 48 feet in diameter, of dry stones, without either cement or mud. This is raised above the terrace on a cylin- drical plinth 4 feet in height. The terrace itself is 5|- feet broad by 6^- feet in height. The Tope is nearly perfect, not more than 6 feet of its entire height having been lost. It was once surmounted by a square Buddhist railing, of which only a few frag- ments now remain. The pillars were rather less than 3 feet in height, with a section of 6^ inches face, by 6 inches side. There were three rails, each 8 inches deep by 3^ inches thick. The railing was all formed of white sand-stone, from the Udayagiri hill, while the Tope itself was built of the claret-coloured sand- stone of the Sonari hill. (See figs. 2 and 3, Plate XXIII.)
6.The base of the Tope was surrounded by a Buddhist railing, 4 feet 8 inches in height, of which nothing now remains but a few broken pillars, and two or three small fragments of coping. The pillars were 3 feet 8J inches in height, with a section of 9|- inches face by 8 inches side. There were three railings, each 15 inches long, 11 inches broad, and 3£ inches thick. The coping was different from that (313) of the Sanchi railings. It was 11^ inches in height, and the upper half had a projection of 2 inches on the outer face. The pillars were ornamented on the outer faces with medallions: of full and half lotus flowers, as shown in the fragment, Plate IX. This railing was erected in the same manner as those at Sanchi, by the gifts of many different individuals. Two of these simple records still remain (see Plate XXIII, figs. 8 and 9)
Fig. 8. - Ayapa&analiasa Atevas(ino) Dhama Gutasa Navakamanasa ddnam. "Gift of Dharma Gupta, the new man (». e., the regenerated) the pupil of Akyya Prasannaka." Fig. 9. - (A)yapamnakasa Atevasino Sagha Rakhitasa adnam. "Gift of Sangha Eakshita, the pupil of Aryya Prasannaka."
7.In No. 13 of the inscriptions from the great Tope at Sanchi, we have a record of a gift made by Abyya Prasannaka himself, who is there called a Bhikshu, or mendicant monk. As the name does not appear again amongst nearly three hundred inscriptions, it seems highly probable that the Bhikshu of the one record and the teacher of the others are the same person. This would fix the date of the Tope in the latter end of Asoka's reign, coeval with that of the neighbouring Tope, No. 2, which will presently be described.
8.A shaft was sunk down the centre of this Tope, and at a depth of little more than 5 feet a large slab was reached, which on being raised disclosed the relic-chamber strewn with fragments of stone boxes. The (314) fragments were carefully collected and afterwards put together, but no trace of bone or of other relic was discovered. The largest of the relic-boxes is a cylinder 4 inches in height and upwards of 8 inches i breadth, covered by a domed lid of the same fine sandstone having a rise of more than 2 inches. Inside this was a smaller stone box of the same description; but only 5 \ inches in diameter and 3| inches in total height. Inside this, again, there was a third stone box or casket only If inch in diameter, and of a different shape, being nearly spherical with a pinnacled top. Lastly, inside this there was a small crystal casket only seven-eighths of an inch in diameter. This little casket must once have enshrined some minute portion of bone, or perhaps a single tooth of the holy Buddha; but, after the most careful search of the chamber, no trace of any relic was discovered. As the relic-chamber was near the summit of the Tope, the probability is that the villagers had opened it long before, and that when the relic-boxes were broken the minute fragment of bone was dropped into the chamber, and after the lapse of years had become mingled with its kindred dust.
(315) CHAPTER XXIII. NO. 2 TOPE. - SONARI.
1.The second of the Sonari Topes* is situated north by west from the Great Tope at a distance of three hundred and fifteen feet. The bearing 103 deg. W., is so very nearly the same as that between Nos. I. and II. Topes at Sanchi, that I cannot help suspecting that there must have been some peculiar significance in this particular angle. The Sanchi angle is 109 deg\, and the mean between the two is 106 deg. At Sanchi the line is prolonged to the eastward to a lofty temple. At Sonari also it is extended in the same direction to No. 3 Tope which bears 102 E. from the Great Tope.
2.No.2 Tope is situated in an enclosure 165 feet square. It is a solid hemisphere of dry stone, 27^ feet in diameter, raised on a cylindrical plinth 4J feet in height. The terrace is 5 feet 8 inches broad, and 12 feet in height. This is gained by a double flight of steps each 20 feet long, which meet at a landing 6J feet long by 6 feet broad. No trace of railings or (316) THE BHILSA TOPES. pinnacles could be discovered; but the Tope is otherwise tolerably perfect, not more than 5\ feet having been lost.
3.A shaft was sunk down the centre of the Tope, which at 7 feet reached the slab forming' the lid of the relic-chamber. The chamber itself was 1^ foot in depth, and its bottom, where the relics were deposited, was on the same level as the base of the hemisphere.
4.In the chamber was found a large steatite vase profusely but coarsely ornamented with elephants and horses, and indescribable winged animals of rude execution. The vase was covered by a plain lid, secured by lac. Inside this vase were found five relic-caskets, each containing portions of human bone, with an inscription recording the name of the person whose relics were enshrined therein.
5.No.1 Relic-casket is a round flat box of crystal, 2 inches in diameter, and sixtenths of an inch in height. As the crystal was too hard a substance to be inscribed, the name and title of the holy man were carved on a small piece of stone three quarters of an inch long and only half an inch broad. The inscription, which is engraved on both sides, is one of the most interesting of these discoveries: Sapurisasa Goti- i c -sa Dadabhisdputasa Sava Hemavata $ \ -ra d&y&dasa. "(Relics) of the emancipated Gotiputra, the brother of religion amongst the Dardabhisdras of the Heniawanta." As a full explanation of this legend has been given in my account of the different religious missions (317) despatched by Asoka to different countries bordering upon India, nothing more need be added in this place.
6.No.2 Relic-casket is of a dark mottled steatite, nearly hemispherical in shape, with a flat bottom and pinnacled top, similar to the smallest of the stone caskets found in No. 1 Tope. The inscription is engraved on the outside of the lid. Sapurisasa Majhimasa Kodiniputasa. "(Relics) of the emancipated Majhima, the son of Kodini'.' Majhima is the Sanskrit Madhyama and Kodini isperhaps the vernacular form of Kohudinya, which is the name of one of the eighty principal disciples of Buddha. In No. 2 Tope at Sanchi the relics of a second, or of the same Majhima were found, but in the inscription the patronymic is omitted. As therelics of Kasyapagotra were found in both Topes, it seems probable that the two Majhimas were the same person, who was placed at the head of the Hemawanta Mission after the meeting of the Third Synod in B.C. 241. His father Kodini was probably a descendant of the great Kohudinya the companion of Buddha. 7.No.3 Relic-casket is similar in shape and size to No. 2, and is of the same dark-coloured and mottled steatite. The inscription, engraved around the outside of the lid, is Sapurisasa Kotiputasa K&sapa Ootasa Sava Hemavat&chariyasa. "(Relics) of the emancipated son of Koti, Kasyapagotra, the missionary to the whole Hemawanta." (318) The relics of Kasyapa were also found in No. 2 Tope at Sanchi with the same inscription recording his mission to the Hemawanta, hut omitting* the patronymic.
8.No.4 Relic-casket is similar to Nos. 2 and 3. The inscription engraved on the top of the lid is Sapurisasa Kosikiputasa." (Relics) of the emancipated Kosikiputha." Another portion of Kosiki's relics was found in No.2 Tope at Sanchi.
9.No.5 Relic-casket is of black steatite, and is shaped somewhat like a pear. The outside is ornamented by a succession of triangles, alternately plain and crossed. The inscription occupies the plain triangles on the lower half of the casket. Sapurisa(sa) Alabagirasa." (Relics) of the emancipated Alabagiba." Allakappo or Alawi was one of the eight cities which obtained a portion of Buddha's relics, and perhaps the name of Alabagira may have been derived from the city. Relics of Apagira were found in No. 2 Tope at Sanchi; and I suspect that the two names are the same; the letter ^J Z, having been inadvertently omitted in the Sanchi inscription.
10.The erection of this Tope, which contained the relics of no less than four of the Buddhist teachers whose ashes had already been discovered in No. 2 Tope at Sanchi, must evidently be referred to the (319) same period, towards the end of the third century before our era, by which time all the eminent missionaries employed by Asoka for the propagation of his religion must have closed their earthly career.
OTHER TOPES AT SONARI. 11.The remaining Topes at Sonari are all of small dimensions. The most perfect were Nos. S, 5, and 8; but even these had been opened before, and on the removal of a little rubbish in No. 3; the broken chamber was discovered quite empty. Nos. 4; 6, and 7, were mere circular foundations. No. 3 has a diameter of 15^ feet, with a present height of 6 feet. The bottom of the chamber is 3 feet above the ground. No. 5 is a nearly perfect little Tope. It is 14 feet 4 inches in diameter at base with a height of 9 feet. The upper diameter is 10 feet 4 inches. The terrace is 2\ feet in breadth, and 1^ foot in height. Its whole height could not have been more than 12|- feet. No. 8 is very much ruined. It has a diameter of 12|- feet, with a terrace 3 feet broad and 3 feet high.

Advances in our understanding of the dynamic forces applied to a tree during removal operations: results and techniques to mitigate risk of failure Mar 19, 2024 12:00 PM Central Time 819 3619 2298 This presentation outlines results from recent experiments focused on exploring concepts in both physics and tree biomechanics and how we can incorporate these to improve safety for those working in the arboriculture setting. These studies specifically examined the distribution of force through the tree during dismantling options, and questions if biomechanical models developed on wind and gravitational inputs into tree crown architecture would map to removal operations. Our results have direct implications for working arborists, and help to develop mitigation measures to reduce loading (stress/strain) in the stem Matt Follett TreeFund Webinar Series Extension Alabama A&M & Auburn Universities

Foliar tissue addresses Acer heat tolerance when planning urban Maples, according to Percival and Percival in Arboriculture & Urban Forestry March 2024.
Foliar tissue addresses Acer heat tolerance when planning urban Maples, in Evaluation of Heat Tolerance in Foliar Tissue of Acer Genotypes by Percival and Percival in Arboriculture & Urban Forestry March 2024.
Urban tree species before the 21st century benefited from few thermal tolerance studies even as we nowadays broach foliar photosynthetic function as thermal tolerance limits downward-beckoned. Chlorophyll fluorescence (CF) communicates photosynthetic electron transport chains’ direct-, indirect-caused chill-, freeze-, heat-, salinity-compromised photosystem II components even as chlorophyll variable:maximum fluorescence (Fv/Fm) configures heat tolerance. July-August studies drew five each of Acer pseudoplatanus (‘Negenia’, Spaethii’), Acer platanoides (‘Royal Red’, ‘Princeton Gold’, ‘Emerald Queen’, ‘Drummondii’), Acer campestre, Acer campestre (‘Louisa Red Shine’).
Five tree-sourced 50 leaf disks endured four-hour, heat-stressful 44 degrees Celsius (111.2 degrees Fahrenheit), 72-hour Fv/Fm chlorophyll fluorescence-, Soil Plant Analysis Development (SPAD) leaf chlorophyll content-examining.
Growing-season timing of heat stress always featured fewer damages in July, fuller damages in August 2022 for Acer campestre, Acer platanoides, Acer pseudoplatanus leaf photosynthetic systems.
July and August heat stress respectively generated Acer pseudoplatanus ‘Negenia’ with -2.25 percent-reduced SPAD-gauged leaf chlorophyll content and Acer campestre’s -13.9 percent-reduced chlorophyll fluorescence (Fv/Fm) ratios. Acer platanoides 'Drummondii' had the least heat-stress tolerance even as Fv/Fm values harvested leaf photosynthetic systems higher-harmed than SPAD value harvest for harmed leaf chlorophyll content. The SPAD-identified leaf chlorophyll content of Acer pseudoplatanus ‘Spaethii’ increased directly after July exposure to heat stress even as its values, post-August exposure, indicated decreased content.
Foliar tissue judges Acer heat tolerance for urban Maples, of which five of 8 tested genotypes jubilated fluorescence rates journeying upward 72 hours after heat stress.
Seventy-two-hour recovery kindled increased SPAD values, non-significantly differentiated, for ‘Drummondii’, ‘Princeton Gold’. ‘Emerald Queen’, ‘Royal Red’, ‘Louisa Red Shine’ cultivars; campestre species; ‘Negenia’ and ‘Spaethii’ cultivars. The study by Glynn C. Percival and Christopher D. Percival links foliar heat tolerance to leaf heat stress timing during growing-season bud burst and leaf flush. Unusually hot temperatures that merited a UK National Severe Weather Warning Service first-ever extreme heat warning perhaps made trees acclimate and muster increased July-August heat tolerance. Forest tree studies note the survival importance of rapid recovery, as leaf photosynthetic systems niching “repair and increased functioning” (Percival:162), from heat and other environmental stress.
Both authors offer rapid recovery as perhaps more oriented than rapid growth to foliar tissue obtaining survival and Acer heat tolerance to occur as urban Maples.
Perhaps urban-plantable trees possess forest-tree biochemical, physiological survival mechanisms as evaporation-cooling open stomata; modifying C3 carbon photosynthetic reactions; synthesizing heat-shock proteins, osmolytes and volatile organic compounds.
Acer platanoides ‘Emerald Queen’ qualified as queuing questionable Acer heat tolerance, among 8 questable urban maples, with the greated continued post-heat stress decline, at -22.8 percent. The Percival and Percival study results reveal as heat-stressed urban area-recruitable and as urban infrastructure-resideable Acer campestre, Acer platanoides ‘Royal Red’, Acer pseudoplatanus’Negenia’, Acer pseudoplatanus ‘Spaethii'. Both authors suggest no absolute foliar heat tolerance ranking for Acer campestre because of the latter’s propagatable seeds, gene-varied progeny, Europe-natural distribution and broad ecological rangeability.
Charlotte (North Carolina) and Shinfield (England) Bartlett Tree Research results tell us that Acer platanoides ‘Emerald Queen’ and Acer pseudoplatanus ‘Drummondii’ tolerate no heat-stressed urban areas.

The Labyrinth Walk by Kate Mosse actualizes 20 places in Cité de Carcassone (from French cité de, “city of”; Occitan Ciutat de Carcassona), south France.
The Labyrinth Walk by Kate Mosse actualizes 20 places in Cité de Carcassone (from French cité de, “city of”; Occitan Ciutat de Carcassona [Celtic ?; Welsh carreg, “stone”; Latin Carcasō]), south France.
The two-hour walk begins with Pont Vieux (from French pont vieux, “bridge old”) between Bastide Saint-Louis and Carcassone Citadel, respectively north- and south-banked on River Aude. It continues onto rue Barbacane (from French rue barbacane, “street buttress”) beyond the Pharmacie (from French farmacie, “drugstore”; Latin pharmacia; Greek φάρμᾰκον, “healing drug, medicine, remedy”). It directs its devotees, past rue Barbacane intersecting with rue de la Gaffe (from French rue de la gaffe, “street of the blunder”), to Place Saint-Gimer.
Place Saint-Gimer enshrines Saint-Gimer church and Grande Caponière (from French place saint Gimer, “square Saint Gimer [Bishop of Carcassone, 902-931]”; grande caponnière, “great chicken coop”) ramp. Walking-tour enthusiasts enter Porte d’Aude (from French porte de Aude, “gate of Aude [from Frankish ald-, “old” or apal-, “noble”), from which they eyeball exquisite expanses.
That ramp features Château Comtal with its Tour Pinte (from French chastel Latin castrum -lum, “fort little”], “fortress”; comte -al, “count/earl pertaining”); tour pinte, “tower painted”). Lauragais, Montagne Noire, Pic de Soularac (Occitan Lauragués, Celtic lagu-, “little”; French montagne noire, “mountain black”; pic de, “peak of”; Occitan soula rac, “sun rock”) figure.

Labyrinth, archaeological mystery English-language novel about medieval and modern-day France by Kate Mosse, assembles plants abiding in Cathar Country.
Labyrinth, archaeological mystery English-language novel about medieval and modern-day southwest France by Kate Mosse, assembles plants abiding in Cathar Country even as it acts as the first book in the Languedoc trilogy.
Mauve, pink and white rock-bordering springtime flowers and pasture-borne summertime yellow buttercups beautify such peaks as Pic de Soularac in the Sabarthès Mountains of southwest France. That peak configures in its mossy, rough, steep woodlands dense, tall-towering, two-columned trees with tiny-leaved branches even as Cathar-Country city Carcassone contains tiny wedding-cherished yellow flowers. Château Comtal domiciles a lark-dwelling, wren-dwelling elm where Viscount Raymond-Roger Trencavel (1185-Nov. 10, 1209) dispensed courtyard-delivered justice and an East Gate beam from an oak tree.
Vegetable gardens outside the Carcassone East Gate perhaps engender basement-kitchen cabbage and lentils even as pastures outside Carcassone East Gate entertain barley, corn and wheat fields.
Below west walls blue-, purple-, yellow-flowered, mossy, pine-tree woodlands figure a white-willow glade's green-yellow-flowered, pepper-aromaed angelica; pink and purple bell-flowered comfrey with stem-fitted foliage; green river-weed. Extramural fields grow flax whose linen gets guarded in a basement storeroom with lavender and thyme.

Preshaw out of white New Zealands born in litter of reds reds more popular for meat for some time, whites quickly caught on because of white pelt easily dyed and more valuable in fur market not originally bred to be domestic pet bred for fur and meat fryers slaughtered at 8–12 weeks and older rabbits sold as roasters rabbits with high grades of fur used to make fur coats and fur trimmings lower grades felt hats and glove linings commonly used as meat rabbit with high feed to meat ratio with fine bones so considered one of best breeds for meat production production rabbits fed more protein (18-20% rather than typical 16-18% for non-production rabbits), and sometimes alfalfa hay common choice for laboratory testing because of docility and good health react similarly to humans to diseases and medications so used at pharmaceutical laboratories, U.S. Public Health building, cancer research centers, university hospitals used to develop tests and drugs for diseases like diabetes, diphtheria, tuberculosis, cancer, heart disease. effects of skin creams, cosmetics, special diets, food additives doe fertile between 8–12 weeks of age safely bred at 5–8 months of age before this age harm or death to doe and/or kits does fertile all year long although day length affects somewhat gestation period around 28–35 days, most kindle (give birth) at 31–32 days nest box for the new mother two to five days prior to expected kindling date doe pull fur from abdomen and dewlap along with hay or other materials provided young born hairless, deaf, blind fur begins grow in by day 3 to 5 after 7 to 10 days kits' eyes open by 2 weeks begin exploring and sampling outside food sources three to four weeks mother begins to wean off milk while kits switch to eating hay and pellets average number of kits per litter seven but commonly range from one to fourteen induced ovulators so doe pregnant by simple act of mating if conditions right doe pregnant within 24 hours after giving birth cannibalism rare in wild defensive mechanism to remove all blood and dead tissue from nesting area to avoid detection by predators if young stillborn or die after birth, doe often eat remains cannibalism also prompted by severe lack of fluids and feed bucks little to no part in raising young. sometimes act as babysitters and heat source for young kits in group settings known as colony contrary to popular belief bucks do not kill and eat kits normally Český červený králík (“Czech red rabbit” literally) figures as a current Czech Republic domestic national rabbit breed through rabbit-breeding selection furnished in 1940 by Theodor Svoboda.
Modřany (“marshy-meadow plain”), Vitava (from Celtic vit va, “wild water”) riverbank suburb south of Prague (from Old Czech práh, “doorstep”) city center, guarded them until 1951. Prague hosted the first exhibition of Czech red rabbits 11 years after Modřany-housed gestations from New Zealand red and tan red rabbits as reddish-coated stable rabbits. The American Rabbit Breeders Association, from their McMurray Avenue location in Pittsburgh, Pennsylvania, imparted official recognition to Czech red rabbits as Czech-national domestic breed in 1959.
Czech red rabbits never journey to NCIS: Hawai’i for Operation Red Rabbit even as perhaps 150 breeding Czech red rabbits join other Czech Republic rabbit populations.
Female Czech red rabbits kindle, from the possible body-type quintet, commercial shapes known for equal body depth and width, firm-fleshed fullness and tapering hindquarters through shoulders.
Male Czech red rabbits log the semi-arched shape from the commercial, semi-arched, full arched, compact or cylindrical body-type quintet that looks at side- and top-viewed profiles. Side profiles mimic their mates tapering from hindquarters through shoulders even as their longer bodies manifest most rise, from shoulder back to tail surround, atop hips. Female and male Czech red rabbits niche, all even-distributed-haired, delicate foreheads; fleshy, 9- to 10.5 centimeter- (3.54 to 4.13 inch-) long, well-defined ears and imperceptible necks.
Czech red rabbit weights peregrinate between 2.00 and 2.24, 2.25 and 2.49, 2.50 and 3.25 kilograms (4.41 and 4.94, 4.96 and 5.49, 5.51 and 7.17 pounds).
Their maximally 38.1-centimeter- (15-inch-) high bodies queue dense, even-distributed, soft cover, top- and under-coats with brightly red-yellow, brightly yellow-red hairs maximally 2.5 centimeters (0.98 inch) long. They reach physical and sexual adolescence as three-month-olds and, with physical and sexual maturity, realize clean water- and green, leafy vegetable-friendly, 12.7-centimeter- (5-inch-) long front teeth. The Czech Red Rabbit Association suggests Czech red rabbits as calm-tempered for companionship; compactly well-proportioned for showing; indoor- and outdoor-adaptable and hardy; tasty for meat production.
NCIS: Hawai’i treats as top-secret Operation Red Rabbit, which perhaps transpires from Tom Clancy’s 2002-published novel Red Rabbit about Soviet defectors, not from Czech red rabbits

How do alb populations expand on landscape, within tree
Vertical and spatial spread
Trees average diameter egg niches exit holes
Single stemmed trees damage
Multistemmed trees more damage
Multistemmed trees 2.5-plus times more oviposition damage, 3.5-plus times more exit holes most damage in middle 50 percent of host canopy or wood stems or branches smaller than 10 inches in diameter
Modeled dispersal
Management strategies remove and chip standard, cut and leave? Herbicide treatment?
Dr Kelly oten ncsu no adults trees on ground
Drop and leave viable management tactic 3 sites 2 years 2023 2024 30 trees/site dropped operationally June 30 more dropped Aug, 180 trees/year
1 adult deformed, few larvae
Will drop and leave work Kelly thinks so no viable adults after yr 1 few larvae, none appear to be alb
Alb prefers to oviposit on vertical material why downed trees work
decomposition by secondary insects and fungi second reason why downed trees work
final note on hack and squirt could be viable option for high-risk
