Our heavy and restful sleep was not broken till long after the sun was glinting upon us through the trees. Our first work was given to building a lodge of underbrush and making preparations for two days' stay on the lonely island, completed by unfurling the signal of the New York Canoe Club from a high stump hard by the camp-fire. Barring the mosquitos, Sunday's rest was a pleasant and refreshing sequence to ten days of toil and struggle, and Monday found us in hearty readiness for a thorough exploration of Itasca Lake and its feeders. We took a lunch, our guns and scientific instruments, and paddled up the south-west arm of the lake to find and explore the leading tributary. We found the outlets of five small streams, two having well-defined mouths and three filtering into the lake through bogs. Selecting the larger of the two open streams, we paddled into its sluggish waters, ten feet wide and one foot deep where they enter the lake. Slow and sinuous progress of two hundred yards brought us to a blockade of logs and to shallow water. We landed, fastened the canoes, took our bearings by compass and started for a tramp through thicket and forest to Elk Lake, which we reached after a rapid walk of thirty-five minutes. This lake is an oval of about one mile in its longest diameter. It lies about half a mile in a straight line south from Itasca. Its shores are marshy, bordered by hills densely timbered. Its sources are boggy streams having little or no clearly-defined course. To all appearance, these bogs and this small lake are the uttermost tributaries to Itasca Lake, and the latter, concentrating these minor streams and sending them out as one, is the true head of the Father of Waters.
Elk Lake was a place of misadventure to us. Our struggle through the thicket and dense forest was hot and exhausting. Our scientist left there a fine aneroid barometer, which a second hot walk failed to recover. Our photographer, arrived at the lake with a grievous burden of camera, plates, tripod, etc., found that he had forgotten his lens tubes, and was compelled to double his tracks back to the canoes, then wade out into the swampy borders of the lake, waist-deep in slime, to secure a view of this highest Mississippi water, only to have his plate light-struck and ruined by an accident on the homeward journey.
