On the 20th, the whole village set out on the march to go the seventeen leagues where the meeting-place for the Mandans had been chosen; every day they entertained us with the tale that the whites we were going to see were Frenchmen like ourselves, who said they were our descendants. All they told us gave us good hope of making a discovery which would deserve attention. Mr. de la Marque and I made plans along the road from what they were telling us, believing that to be true, from which we had to deduct much. I observed to Mr. de la Marque the good order in which the Assiniboines march to prevent surprise, marching always on the prairies, the hill-sides and valleys from the first mountain, which did not make them fatigued by mounting and descending often in their march during the day. There are magnificent plains of three or four leagues. The march of the Assiniboines, especially when they are numerous, is in three columns, having skirmishers in front, with a good rear guard; the old and lame march in the middle, forming the central column. I kept all the French together as much as possible. If the skirmishers discover herds of cattle on the road, as often happens, they raise a cry which is soon returned by the rear guard, and all the most active men in the columns join the vanguard to hem in the cattle, of which they secure a number, and each takes what flesh he wants. Since that stops the march, the vanguard marks out the encampment which is not to be passed; the women and dogs carry all the baggage, the men are burdened only with their arms; they make the dogs even carry wood to make the fires, being often obliged to encamp in the open prairie, from which the clumps of wood may be at a great distance. On the morning of the 28th, we arrived at the place selected for the meeting with the Mandans, who arrived towards evening--a chief with thirty men and the four Assiniboines. The chief having from the top of a height considered the extent of our village, which appeared of a good size, I had him brought to the hut where I was, where a place had been prepared to receive him on one side of it. He came and placed himself near me; one of his people then, on his part, presented me with a gift of Indian corn in the ear, and of their tobacco in rolls, which is not good, as they do not know how to cure it like us. It is very like ours, with this difference, that it is not cultivated and is cut green, everything being turned to account, the stalks and the leaves together. I gave him some of mine, which he thought very good. I acknowledged that I was surprised, expecting to see different people from the other Indians, especially after the account given me. There is no difference from the Assiniboines....
