" Emergency tanning method is as follows. Dry deer and animal brains, then boil them in enough urine to form a thin cream-like solution. Soak the raw hides in the solution for 24 hours, then remove them and stretch and pull the hides continuously for at least a half hour over the rounded end of an eight inch or larger log. Pull and stretch the hides until they are dry or practically dry. This is the Ojibway method of tanning raw hides. "
