272, _West Town, N. Y._--Most of us are attending school away from home. We therefore disband through the winter, and then reorganize for the summer vacation, and work as much as we can, for we have farm work to do besides. Still we can study as we work, and we do this. Our minerals are all labeled and mounted. We have about 200 birds' eggs, some of them quite rare. We pride ourselves on our insects. I think we have 300, still am not positive. Our botanical specimens number 200. The work we have done, though not very great, has done us a great amount of good.--William Evans, Sec. SOME IMPORTANT QUESTIONS. MANCHESTER, VT. I am extremely anxious to experiment during the coming season with the American silk-producing worms, not for the purpose of producing raw silk, but for other reasons of scientific and practical interest. I wish to learn the best books for giving a knowledge of the habits of _Attacus Cecropia_, _Polyphemus_, and the Promethean moths. I shall be glad of any information regarding the best places to find their cocoons. I should like to hear of the experience of others in finding cocoons, and raising the moths. I have M. Trouvelot's papers on the subject, Dr. Garlick's letters on his experiments; also Dr. Stirling's, Prof. Riley's report on Silk Production No. 11, Packard's "Our Common Insects," Sir John Lubbock's "Origin and Metamorphosis of Insects." I should like the addresses of any parties who have cocoons of the said moths to dispose of; and finally, information regarding the success or failure of any who may have tried the experiment of raising the worms. Very truly yours, C. F. ORVIS. [_Mr. Orvis is a member of the A. A., has been for years engaged in an important manufacturing business, and we trust may obtain from "those who know," all the information he desires._] EXCHANGES.
