Although an enumeration of all the 

 different kinds that infest plants at dif- 

 ferent periods is more than the limits 

 of this work will admit, yet, these in- 

 stances may serve so far to give an idea 

 of their nature, that persons who feel in- 

 terested may employ such means for 

 counteracting these great evils, as may 

 appear most likely to answer the pur- 

 pose. 



It should be observed, that in general 

 each kind of insect has its particular food, 



small kind of grasshopper described by naturalists 

 as coming regularly once in seventeen 3'ears, and 

 is called Tettigonia Septendecem from that circum 

 stance. But a more extraordinary account is pub- 

 lished by Mr. Marsham, in the Transactions of the 

 Linnsean Society of London, of an insect which was 

 known to have existed in a deal board that had been 

 converted into a writing desk in Guildhall. The length 

 of time it had been enclosed therein was uncertain, 

 but it was a known fact that it must have been there 

 upwards of forty years. It is moreover a curious cir- 

 cumstance, that its kind has never been noticed in 

 this country before, and that it is a native of China, 

 but is also sometimes found in Norway, and from 

 the latter country it is probable the timber in which 

 it was enclosed, was imported.
