Less complete, but still adequate, data from the Blackfoot, Menomini, and Pawnee indicate that in the upper Mississippi area we had a generalized type of this process in contrast to the coil method. Eastward in the northern Algonkin area our data are not so good, but it is generally believed that the coil process prevailed, except in the farthest north where the pottery was very crude.
This upper Mississippi, or Mandan-Hidatsa type has a striking resemblance to Alaska-Siberian pottery. The studies of Jochelson and Bogoras[2] show one general method for Alaska and eastern Siberia, a method closely paralleling the
