Annual report of the Bureau of Ethnology to the Secretary of the Smithsonian Institution . ax is hafted. The groovedtools were undoubtedly used in this way, and many of the groovelessforms could have been attached as is the ordinary primitive adz.

With short handles, such as indicated in figure 17, effect-ive and very neat work could be done, aud it may be remarked thatsuch a tool could be handled in the cramped quarters in which thecutting was often carried on almost as conveniently as could the chiseldriven by a mallet. Among the chisels there are numerous slightly curved forms, somewith one ground point that could have been hafted as in a, figure 17,and others with two points that may have been mounted so as to makeboth points effective, as in h, figure 17.
