 I notice this circumstance merely as 1 

 hope some persons whose time may per- 

 mit them, may be able to carry the 

 examination of these animalculae so far 

 as to give us a much more perfect idea 

 of their nature than we have at pre- 

 sent. There is no subject that demands 

 investigation more than this, and nothing 

 would produce more benefit to this coun- 

 try, and probably the world at large, than 

 proper encouragement being held out to 

 personsto make the necessary experiments, 

 and to publish the results arising there- 

 from. If the growth of fruit, or the 

 produce of cyder, is of any moment to us 

 as a country, it is necessary that atten- 

 tion should be immediately paid to this 

 subject, or the result will most inevit- 

 ably be, the destruction of apple trees al- 

 together ; and as the insect is beginning 

 to attack otlier kinds of fruit-trees, it is 

 not inu'easonable to suppose that the mis- 

 chief mav not end with that loss alone.
