grows within the bloffom is its food, and by the 
time it has eaten the whole thereof, it is full grown, 
and: then it foon becomes in a fufpended ftate. 
When it firft enters the bloffom it is a fmall worm, 
of an afh colour, witha blackifh head; as it grows 
larger it grows whiter, and retains its whitenefs, un- 
til it is come near to perfetion, and then ita day or

the fly before-mentioned. To this infe&, I believe, 
might be attributed: the failure in apples this year, 
and not to a blight, as ftated of late in the 
new/{papers. 
Thefe refearches and difcoveries cannot be of any 
benefit to the publick, unlefs fome preventive can .

perfons, that in time paft have been. engaged in 
fmoking orchards, and have been particular in my 
enquiries on the fubject as to the benefit. They 
differ; for one fays, he thinks it has been attended 
with benefit; while another fays, he thinks it has 
not anfwered much; but as to the time of pérform-

of the bloffoms have been for fomé time open, or 
fo long as to begin to fall off; and then, if they 
perceive that’ others have not opened, they fufpeét 
the caufe to be the worm; and if on examination, 
they find it to be fo, they then fmoke the trees. 
This certainly is the time for difcovering the infeé,
