■ MANAGEMENT OF FRUIT TIlEES, &c. 26 § 



If any Caterpillars fhould remain, they will be difcovered 

 by the curling of the leaves ; for every curled leaf has one or 

 more caterpillars, or other infects, in it ; they fhould there- 

 fore be carefully pulled off, and the infects crulhed : if neg- 

 lected, they will frequently devour every leaf, leaving the 

 tree quite naked, and of courfe deitroy the fruit for that 

 feafom 



There are fome gregarious forts of caterpillars found ini 

 great numbers enclofed in a net,- or bag, refembling a ftrong 

 cobweb, and fixed to the branches' of trees and fhrubs. Thefe 

 Belts fhould be carefully picked off, and the infects crufhed, 

 by which vaft numbers of them will be deftroyed. After you? 

 have cleared the tree as well as you pofhbly can, wafh it as 

 above directed,, which will deftroy thofe ftragglers that may 

 Hill remain on it. 



Obferve, that after the trees come into flower, inftead ©£ 

 wafhing them with urine and foap-fuds, they fhould be welk 

 watered with clear lime-water, mixed with tobacco-water. 



There are feveral fpecies of moths that in the caterpillar 

 ftate are very hurtful to plums and other fruit-trees : it will,, 

 therefore, be a great advantage to deftroy them on their firft 

 appearance. 



It would be of great fervice to get acquainted as much a& 

 poffible with the economy and natural hiftory of all thefc 

 infects, as we might thereby be. enabled to find out the moft 

 certain method of defiroying them. Were a few of each fort 

 of caterpillars put in a box or cafe, and fed with leaves of 

 fuch trees a£ they generally live upon, they might be obferved 

 from time to time until they came to the chryfalis, and from, 

 that to the moth or butterfly ftate, and thus a more perfect 

 knowledge of them might be obtained,
