"March 25, 1805.--A fine day, the wind south-west. The river rose nine inches, and the ice began breaking away. Our canoes are now nearly ready, and we expect to set out as soon as the river is sufficiently clear of ice to permit us to pass. "March 29.--The ice came down this morning in great quantities. We have had few Indians at the fort for the last three or four days, as they are now busy in catching the floating buffaloes. Every spring, as the river is breaking up, the surrounding plains are set on fire, and the buffaloes tempted to cross the river in search of the fresh grass which immediately succeeds to the burning. On their way, they are often insulated on a large cake or mass of ice which floats down the river. The Indians now select the most favorable points for attack, and, as the buffalo approaches, run with astonishing agility across the trembling ice, sometimes pressing lightly a cake of not more than two feet square. The animal is, of course, unsteady, and his footsteps insecure, on this new element, so that he can make but little resistance; and the hunter who has given him his death-wound paddles his icy boat to the shore, and secures his prey." CHAPTER VI. THE MARCH RESUMED. From the 1st of November, 1804, to the 1st of April, 1805, the expedition remained stationary at their fort. Some of their number had been sent back to the States with despatches to the Government, and with specimens of the natural productions of the country. On resuming their march on the 4th of April, the party consisted of thirty-two persons. Besides the commanders, there were three sergeants,--Ordway, Prior, and Gass; twenty-three privates, besides Capt. Clark's black servant York; two interpreters,--George Drewyer and Toussaint Chaboneau. The wife of Chaboneau, an Indian woman, with her young child, accompanied her husband. All this party, with the luggage, was stored in six small canoes and two pirogues. They left the fort with fair weather, and, after making four miles, encamped on the north side of the river, nearly opposite the first Mandan village. We continue their journal. THE RIVER-SHORE.
