Carver left Boston in the month of June, 1766, and proceeded to Mackinaw, then the most distant British post, where he arrived in the month of August. He then took the usual route to Green Bay. He proceeded by the way of the Fox and Wisconsin rivers to the Mississippi. He found a considerable town on the Mississippi, near the mouth of the Wisconsin, called by the French "La Prairie les Chiens," which is now Prairie du Chien, or the Dog Prairie, named after an Indian chief who went by the dignified name of "The Dog." He speaks of this town as one where a great central fur trade was carried on by the Indians. From this point he commenced his voyage up the Mississippi in a canoe, and when he reached Lake Pepin he claims to have discovered a system of earthworks, which he describes as of the most scientific military construction, and inferred that they had been at some time the intrenchments of a people well versed in the arts of war. It takes very little to excite an enthusiastic imagination into the belief that it has found what it has been looking for. He found a cave in what is now known as Dayton's Bluff in St. Paul, and describes it as immense in extent, and covered with Indian hieroglyphics, and speaks of a burying place at a little distance from the cavern,--Indian Mound park evidently,--and made a short voyage up the Minnesota river, which he says the Indians called "Wadapaw Mennesotor." This probably is as near as he could catch the name by sound; it should be, Wak-pa Minnesota. After his voyage to the falls and up the Minnesota, he returned to his cave, where he says there were assembled a great council of Indians, to which he was admitted, and witnessed the burial ceremonies, which he describes as follows: "After the breath is departed, the body is dressed in the same attire it usually wore, his face is painted, and he is seated in an erect posture on a mat or skin, placed in the middle of the hut, with his weapons by his side. His relatives, seated around, each harangues the deceased; and if he has been a great warrior, recounts his heroic actions nearly to the following purport, which in the Indian language is extremely poetical and pleasing:
