The rc-appea;'a'ice of those armies of Ca':erp!liars 

 wiiicl! infested, and even dcs!i->yed, so manv of oiH" fruit 

 trees ia-t sun>mc!-, has this year induced me to make the 

 foliowing- cxperi ricf!' s : 



1. On a young apple tree, at the bifurcation of the 

 f'rst limb, I made a mouidiu,'^ of chiy mortar, (al)out 14 

 daysag-o.) O;" the 3:1 day, 1 observed an unusual com- 

 motion of the worms ; and tliat they .appeared vsqak, 

 emaciated, and theii" bright colour much diminished, ap-

 and formed a new web over it. These f displaced, and 

 gave the moulding a coat of fresh mud. They are now 

 entirely gone. 



2. On a clierry tree in my meadow, where a vast 

 number of tliose vermin had nested, and devoured a!! the 

 leaves,! placed a sofi, so as to encompass the trurdc, and 

 be supported by the ih-st [irab. On the Tth duj, the iiesfc
