One day, in the spring of 1937, while looking at some Indian artifacts in Peabody Museum at Harvard University, I saw a card of flaked stone objects that had been made by Mr. F. R. Whitney of Tacoma, Washington. The card stated that more information concerning these pieces might be obtained in the Museum Library. I promptly went to the Librarian and asked about them. She told me that if I were interested in the manufacture of stone arrow points I should get in touch with Mr. Charles E. Snow, who was then a student of anthropology at the University.
