THAT INFEST THE VINE. 
167 
To one pound of dowers of fulphur put two ounces of com- 
mon fcotch fnuff'i (very good tobacco dud will anfwer equally 
well.) Let thefe be well mixed together j then take a final 1 
brufh, fuch as is ufed for common painting, dip it lightly in 
the fulphur, then lay one hand on the upper furface of the 
leaf, and with the other draw the brufli very gently backwards 
and forwards all over the under-fide: By this means a little 
fulphur will be left on the leaf. The Acarus being foft and 
delicate in its nature, is hereby deftroyed with the mod gentle 
touch : The brufh alfo mod readily wipes off their web as 
well as their globular tranfparent eggs, which are by a fine 
membrane fadened to the leaves ; and thus we are fecured 
from the danger of a fucceeding brood. 
This procefs may to fome have the appearance of a tedious 
operation; and indeed, when Vines are injudicioufly train- 
ed, it certainly mud be attended with great trouble; but it is 
very eafily performed uponVines trained in the regular method 
here fet forth ; and a fingle operation is generally fufficient for 
a whole feafon. 
I have commonly given a general dreffing to the Vines in the 
Pine- dove at V/elbeck, as foon as I have obferved the Acari 
make their appearance upon any part of them ; and I have 
feldom found it needful to repeat the operation during the 
dimmer.
