These gentlemen can hardly realize how great a 

 service they are rendering. There are thousands of 

 young and older amateur naturalists belonging to our 

 society, most of whom, living in remote towns, have 

 few opportunities of instruction in the subject of their 

 choice. They are now placed in such a position that 

 they can go on with their observations without leaving 

 home; can be advised as to the best books for con- 

 sultation in their several departments ; can exchange 

 specimens and thoughts with members in all the 

 different States and Territories ; and can have the 

 assistance of men trained in special departments of 

 science, and all without expense. May not the A. A. 

 be the means of solving one of the most perplexing 

 educational questions of the day ? 



CONDITIONS OF CORRESPONDENCE. 



The following rules must be strictly regarded not 

 only in corresponding with the gentlemen just named, 

 but also in addressing the President. 



i. Enclose in each letter, requiring an answer, a 

 stamped and addressed envelope, or a postal-card. ( The 

 envelope is better, as we frequently wish to reply by a 

 circular or full letter?)
