length, and the depth averages perhaps one-half the 
width. This form may have been suggested by wooden 
dishes or mortars of like shape, examples of which are 
still in use among some of the Algonquian tribes. Other 
forms approach more nearly a circular outline, as viewed 
from above, and these usually have greater depth. In 
cases the outline is somewhat rectangular* Roughed-out 
cups of small size are sometimes found. ( W. H. Holmes 
in 15th Annual Report B. A. E., 1893-94.)
