Indian Archery : Page 426
Feathers from the hawk, eagle, goose or turkey were usedin fletching. The feathers were stripped, cut to length andbound on with thin sinew thread. While the feathers wereproperly placed on the arrow, they appear not to have gluedthem in position. Their feathers were from 4 inches to 5inches long and, as a rule, were not trimmed to any shapeor pattern. I have seen some Seneca arrows that had thefeathers trimmed to shape; Ishi did trim his feathers.
The arrow nock was a deep and well formed cleft. Theforward end of the footer was fashioned with a notch toreceive the stone head.
ARROW HEADS
Arrow heads were made mostly from flint and obsidian(volcanic glass). They were made by shaping thin pieces ofthese materials by pressure flaking. Where they learned thisart, no one knows. The Neanderthal boys invented the proc-ess a hundred thousand years ago; Folsom man used it inAmerica 25000 years ago. It could have been that the artwas carried eastward where it was adopted by the progenitorsof the mongoloids from whom the Indian is believed to havesprung. Anyway, the Indian culture of pressure flaking hadreached a stage of development comparable to the Magdale-nian period of prehistoric Europe.
