When the winged infect tribe firft begin to ap- 

 pear, (which fome conceive, and not improbably, 

 to be by an eaft wind bringing fome forts at lead of 

 them over from the continent) I would recommend 

 fome heaps to be made of the fward or fpind, in the 

 nature of denfhiring or burnbaiting, or heaps of long 

 dung, wet draw, weeds, or any other like matters, 

 at different intervals all around, i. e. on every fide, 

 and likewife fome in different parts of the orchard. 

 If an eaft wind blow, fet fire to fome of the heaps 

 on the eaft fide, and fome within the body of the 

 orchard; if a fouth wind, then on the fouthfide; 

 and fo occafionally on different (ides, as the wind 

 may happen to vary; but always on that fide from 

 whence the wind happens to blow, fo that the fmoke 

 from the fmothering of the heaps may blow through 

 and fumigate the orchard for fome weeks. The 

 expence attending which will comparatively be very 

 trifling, but its confequences and beneficial effects 

 very great, as it will effectually prevent the infect 

 fiy not only from depofiting its eggs, but even from 

 approaching, or at leaft continuing long in fuch a 

 noxious fituation, whereby the bloffoms and fruit 

 will be prefer ved from fuch ravages, and the heat 

 and afhes of the fmothering heaps will likewife con- 

 tribute to the fertility of the foil, the fweetnefs of 

 the pafture, and the growth and vigour of the trees
