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.
