certain articles of dress, cooking pots, and various other household
articles as well as salt and some animals. The knives made by him are in

occasionally brought in. Two examples of this trade are now in the
collections of the Field Museum of Natural History. One is a jacket made
from Javanese cloth; the second a belt buckle which apparently

Plate XXXII), and at times bows and arrows (Fig. 17). For defense they
