which appeared next summer in his garden. He says, that 

 lime water and soap suds, used as a wash, will kill them. 



Aug. 16, 1797. The exceeding wet season which we have 

 had all the summer, near four inches of rain falling in June, 

 has checked the insect so much, that it is hardly to be seen, 

 and does not seem to have done any mischief to the Apple 

 trees at Spring Grove. The Codlins, which in the beginning 

 of the last year seemed mortally affected, have recovered 

 their vigour entirely, and bear a heavy crop of fruit. 



The insects are, however, by no means exterminated ; 

 little white clusters of them are to be seen in fissures of the 

 bark, or in cankery places. 



Aug. 29. Tried an experiment on my Codlin trees at 

 Spring Grove, in the hope of lessening the breed of insects. 

 The dead and cankery part of the bark was cut off from the 

 living part, on their trunks and main branches, and the whole 

 surface, deprived of dead bark, was painted over with a 

 mixture of one pound of flour of brimstone mixed with four 

 of soft soap.
