100 CULTURE AND MANAGEMENT 



its mode of operation, he may apply the brush with 

 his hand to a nest within his reach. Spruce poles 

 are eligible, because that wood is light and stiff. 

 For my small trees, I found a common bean pole 

 (used for running beans to climb on,) six or seven 

 feet long, sufficient ; and for them a larger pole 

 would be inconvenient. For taller trees, poles pro- 

 portionably long must be provided. 



If you are satisfied, by my account, of the utility 

 of this simple instrument for destroying caterpillars, 

 you may think it proper immediately to make it 

 publickly known. Should the description be more 

 minute than is requisite for communicating a clear 

 idea of it, and of its application, you will abridge it. 



With respect and esteem, &c.

THE WORM CALLED THE BORER. 



An interesting paper by W. Denning, Esq. on the 

 subject of the alarming decay of apple trees, is in- 

 serted in the first volume of the transactions of the 

 New York agricultural society; from which it ap- 

 pears, that on cutting down some apple trees, which 

 were far decayed, he discovered two worm holes 

 running perpendicularly, from the tap root, through 

 the heart. These holes were large enough to ad- 

 mit a pipe stem, and reached about fourteen inches 

 above the surface ; and from each hole a worm 

 was taken. In some trees eight or ten holes were 

 found. Mr. Denning proposes no remedy ; but 

 Dr. Mease, editor of the domestick encyclopedia, 

 observes, that the worm must be searched for with 

 a wire, and bored out. The publick are particu- 

 larly indebted to J. Prince, Esq. and to Mr. E. Her- 

 sey, of Roxbury, for their mode of destroying this 

 pernicious insect.
