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.]
