OF TREES AND PLANTS. 153 



i. Bay-leaved, fiveet-fcented Willow (n). In moift hedges and mea- 

 dows, and about ditch-banks. In the Roman fofs between Sheiv- 

 ingjheels and Carraiv. In the hedge by a ftreamlet on the fouth 

 fide of their ftation at Houfe-Jlecds ; and many other places by the 

 Roman wall, in great abundance. The young fhoots in May, 

 after a warm fhower, are very fragrant. It is frequently the 

 fummer ornament of the pheafant's chimney. The down of the 

 catkin is like cotton, of a beautiful whitenefs. Infects terebrate 

 the leaves to dfipofite their 0<va. The organ, with which they 

 perform it, is well defcribed by Malphigius in his anatomy of 

 plants. We find the fame Cuniculi on the leaves of the common 

 willow, and on the twigs of the wild rofe, and of the oak. Thofe 

 of the oak are ufually called Oak-apples, from their globofe figure 

 and likenefs to a fmall apple, and Oak-galls, from their being tinc- 

 torial and giving a black dye. Thofe of the wild rofe are large, 

 of an irregular figure, filimentofe, of a greenim-yellow, tinged 

 with red. The twig of a young white thorn in a dwarf-hedge 

 in my garden had the moft remarkable gall-tumour of any I 

 have obferved ; a villofe, filiform matter covering it all round, 

 except at the lateral and terminale buds, fo like the downy coat 

 of that little animal the Mole, that I at firft fight fancied it was 

 part of the fkin of one, till I raifed the bark with a penknife, and 

 found it to be the generative Nidus of an infect ; the obftructed 

 juices taking that form on the exterior Cortex through the pores, 

 the hairs being fo many tubes whereby the wounded twig re- 

 ceived nouriftiment from the air and dews ; an effort of nature 

 to keep itfelf from deftruction.
