Hidatsa, he tells us, is the name by which they call themselves. They are better known to us by the names Minnetaree and Gros Ventre. This last is a name given them by the Canadian French, and without any special reason. It is a fact that Indians can eat large quantities of food, but it is very rarely indeed that you will find one whose appearance would justify the epithet _gros ventre_. The other term, Minnetaree, is the name given them by the Mandans, and means, _to cross the water_. The story is that when the Hidatsa people came to the Missouri River from the north-east, the Mandan village was on the west side of the river. They called over, and the Mandans answered back in their own language: "Who are you?" The Hidatsa, not understanding it, supposed they had asked, "What do you want?" and so replied; "_Minnetaree, to cross over the water_." Whence came the Hidatsa? Their legend says they originally lived _under_ a great body of water which lies far to the north-east of where they now live. From this under-water residence some persons found their way out, and, discovering a country much better than the one in which they lived, returned and gave to their people such glowing accounts of their discoveries that the whole nation determined to come out. But, owing to the breaking of a tree on which they were climbing out of the lake, a great part of the tribe had to remain behind in the water, and they are there yet. This is very much like the myth of another tribe, who lived under the ground by a lake. A large grape-vine sent its tap-root through the crust of the earth, and by that they commenced to climb out. But a very fat woman taking hold of the vine, it broke, and the remainder were doomed to stay where they were. Do such legends contain any reference to the great Deluge? After the Hidatsa came up, they commenced a series of wanderings over the prairies. During their migrations they were often ready to die of hunger, but were always rescued by the interference of their deity. It was not manna rained down around their camp, but the stones of the prairie were miraculously changed into buffalo, which they killed and ate. After some time they sent couriers to the south, who came back with the news that they had found a great river and a fertile valley, wherein dwelt a people who lived in houses and tilled the ground. They brought back corn and other products of the country. To this beautiful and good land the tribe now directed their march, and, guided by their messengers they reached the Mandan villages on the Missouri River. With them they camped and learned their peaceful arts. Dr. Matthews says they have a tradition that during these years of wandering the Genius of the Sun took up one of the Hidatsa maidens, and their offspring came back, and, under the name of Grand-Child, was the great prophet and teacher of his mother's people. Can that have any reference to the "Son of Man"?
