Construction
The whistle is made by removing the fat and marrow from the long wing bone of a bald or golden eagle. The bone is then boiled until all of the fat and tissue is removed, and sanded. The large flaring end of the bone is opened and the bone is cut to approximately 7 inches (17 cm) in length. A concave lens-shaped opening is then filed or bored out of the bone to form the whistle opening. Pitch from a pinyon pine tree is then placed into the opening and the bone is heated until the pitch is softened. The pinyon pine pitch is then shaped into a ridge and allowed to harden.

—John Dewey (1859–1952)
“There’s no art
To find the mind’s construction in the face:
He was a gentleman on whom I built
An absolute trust.”
