Having reached a part of the stream which could be safely navigated, I resolved to re-embark after supper, and continue the descent by night. We were now about fifteen miles above the primary forks. Lieut. Allen determined to remain till daylight, in order to trace the river down to the point at which it had been left in the ascent. Nothing of an untoward nature occurred. A river of some size enters, on the left hand, about six miles below the saurian encampment, which originates in a lake. This stream, for which I heard no name, I designated _Allenoga_, putting the Iroquois local terminal in _oga_ to the name of the worthy officer who traced out the first true map of the actual sources of the Mississippi.[173] We passed the influx of the east fork, about half-past one A. M. on the 15th, traversed the Lake of Queen Anne, and descended the whole series of the Metoswa rapids, to Lake Andrúsia, by the hour of daybreak, and reached the island of my primary encampment, in Cass Lake, at nine o'clock in the morning. We had been eleven hours and a half in our canoes, from the time of re-embarkation at the camp above Allenoga. Lieut. Allen did not rejoin us till six o'clock in the afternoon. He estimated the entire distance, _out_ and _in_, at 290 miles, it being 125 miles to Itasca Lake, and, as before intimated, 165 miles from thence to Cass Lake. He estimates the length of the Mississippi, above the Falls of St. Anthony, at 1,029 miles. Taking the distance from the Gulf of Mexico to the Falls at 2,200 miles,[174] this would give to this stream a development of 3,229 miles, which exceeds my prior estimates more than fifty miles. [173] Lieut.-Col. James Allen, U. S. A. This officer graduated at West Point in 1825. After passing through various grades, he was promoted to a captaincy of infantry in 1837. He was lieutenant-colonel and commandant of the battalion of Mormon volunteers in the Mexican war, which was raised by his exertions, and died at Fort Leavenworth, on the Missouri, on the 23d of August, 1846. [174] Doc. No. 237. CHAPTER XXV. The expedition proceeds to strike the source of the great Crow-Wing River, by the Indian trail and line of interior portages, by way of Leech Lake, the seat of the warlike tribe of the Pillagers, or Mukundwa.
