elder leaves are, and from thence, reafoning how much 
more fo they muft be to thofe of a butterfly, whom 
I coniidered as being as much fuperior to us in 
delicacy as inferior in flze. Accordingly I took fome 
twigs of young elder, and with them whipt the cabbage 
plants well, but fo gently as not to hurt them, juft as the 
butterflies firfc appeared ; from which time, for thefe 
two fummers, though the butterflies would hover 
and flutter round them like gnomes or fylphs, yet I 
could never fee one pitch, nor was there I believe a 
Angle catterpiller blown, after the plants were fo 
whipt ; though an adjoining bed was infefted as 
ufual. 
2d. Refleding on the efteds abovementioned, and 
confidering blights as chiefly and generally occafi- 
oned by fmall flies, and minute infeds, whofe organs 
are proportionably finer than the former, I whipt 
the limbs of a wall plumb tree, as high as I could 
reach ; the leaves of which were preferved green, 
flourifhing, and unhurt, while thofe not fix inches 
higher, and from thence upwards, were blighted, 
fhrivelled up, and full of worms. Some of thefe 
laft I afterwards restored by whipping with, and 
tying up, elder among them. It mufi be noted, that, 
this tree was in full bloflbm at the time of whip- 
ping, which was much too late, as it fhould have 
been done once or twice before the bloflbm appeared.. 
But I conclude from the whole, that if an in- 
fufion of elder was made in a tub of water, fo that 
the water might be drongly impregnated therewith,, 
and then fprinkled over the tree, by a hand engine,, 
once every week or fortnight, it would effectually 
anfwer.
