I wish to inform correspondents that my stock of South American stamps is exhausted. I will now exchange postmarks, and pieces of an idol found in an Inca Indian grave, for insects. Butterflies, moths, and a burying-beetle especially desired.

I wish to notify correspondents that my stock of curiosities for exchange is exhausted. If any have sent me specimens, and have received no answer, I wish they would inform me.

Jennie Harrington.


I have no more minerals to exchange for silk scraps. I have a collection of from sixty to eighty different kinds of rare bugs, which I will exchange for something of equal interest. Correspondents will please write what they will give.
