Drawing made in a boardinghouse. This turtle shell, and others like it, is used as a rattle in sacred tribal dances. This one was brought by the original Seneca into Indian Territory in 1830. Never photographed as a camera might capture its soul, I was allowed to draw it because no such superstitions involved my pencil" on mat
