6. North Pacific bow; round grip and flat wings, generally of yew or cedar.
7. Columbia River bow; similar to number 6, with wings much shorter and the necks sharply incurved.
8. Interior Basin bow; a long, slender stick, lined on the back with shredded sinew, strengthened by cross-wrapping here and there.
9. California bow; like number 7, but neatly lined with sinew and ornamented.
10. Pueblo bow; like number 8, but frequently without backing. In the southern portion of this area long cottonwood bows with cross-lashing are used by the Yuman and Piman Indians.
11. Middle American bow; hard palm wood, long and rectangular in cross-section; in the northern portion, short and flat.
12. Antillean bow. Little is known of this type, but probably it resembles the types of the Venezuela and Guiana regions, which are long and slender.
13. Cordilleran bow. Wherever the sling was predominant the bow was not much used, and this is true of the highland regions of South America. The Amazonian type intrudes here.
14. Upper Amazon bow; of palm wood, rectangle or long ellipse in section.
15. East Brazilian bow; of hardwood, semicircular in section, mixed southward.
16. Mato Grosso bow; bows of the east and west overlapping.
17. Argentina bow; of hardwood, small, round in section, disappearing after the introduction of the horse.
18. Fuegian bow; round in section and small.
No less interesting than the bow is the arrow in its geographic distribution throughout the western world. On the whole, the structure has not been materially changed by the introduction of metal, iron and brass taking the place of stone and other substances.
