About the year 1845 many Hidatsa removed from the vicinity of Knife River and reared a new village not far from Fort Berthold, some 60 miles up the Missouri from old Fort Clark. They were joined from time to time by other members of their tribe, and also by many of the remaining Mandan. In 1862 the Arikara became the third tribe to settle near Fort Berthold. But in 1850 the Arikara continued to occupy the old Mandan town just below Fort Clark, the large village of earth lodges so often visited and mentioned by the explorers and traders during the early years of the last century. It is quite evident the new settlement of the Hidatsa did not differ in appearance from the old Mandan town, the later home of the Arikara, and on June 13, 1850, Culbertson wrote from Fort Berthold: "The village, with its mud lodges, differs nothing in looks from the Ree village described yesterday, except in one particular, that is, the inhabitants are now engaged in surrounding it with pickets. The logs are well prepared and are all up except on the west side; a bastion with loop holes is placed in the middle of each side. This picket is of course to protect the inmates against enemies by whom they are frequently attacked." (Culbertson, (1), pp. 118-119.) This is a most interesting reference. Could this palisade have been the one to which Matthews alluded as having stood until 1865? The manner of constructing the palisade, with "a bastion ... in the middle of each side," will tend to recall the similar arrangement as indicated on the drawing of the ancient Mahican village about two centuries before. (Bushnell, (1), p. 26.)
