28o ATREATISEOF 



I have found thefe methods fuccefsful^. 

 even v^hen the flies have been very ftrong 

 upon the trees, and have, in a few days, 

 deflroyed niany of them, and caufed the 

 trees to fhoot vigoroufly. 



There is another method that more ex- 

 peditioufly kills the flies, but it is fubjeft 

 to kill too many of the leaves, if made too 

 flrong, and is alfo detrimental to the fruit. 

 However, the manner that I have per- 

 formed it with the greateft fuccefs, is this : 

 mix v^^ater with fait, two ounces to the 

 gallon ', then take fuch a bruih as is men- 

 tioned amongft the inftruments ufed in 

 gardening, dipt in the water, after the 

 fait is quite diflblv'd, and wafh the trees 

 with it in the evening, obferving to begin 

 at the bottom of the tree, and make all 

 the fl:rokes upw^ards : by that means the 

 water will fall chiefly on the under fide of 

 the leaves, where it is mofl: wanted. This 

 will occafion the infefted leaves to drop off 

 the trees, but will not injure the healthful 

 ones ; and if it be not too late in the fum- 

 mer, the trees will make good fhoots after, 

 even fuch as will produce fruit the next 

 year on peaches or neftarines.
