Note 4 — Chapter IX
Reading edition
These arrows are of hard wood, well polished, and quite straight. They are about two feet in length, and in a notch at the point have a sharp triangular piece of agate, obsidian, or broken glass; which is not permanently fixed, and therefore remains in a wound, though the shaft may be drawn out. The bow is from three to four feet long, quite plain, with a string made of twisted sinews.
