Next day two interesting observations were made; down by the shore I found the midden-heap of a Lemming family. It contained about four hundred pellets: their colour and dryness, with the absence of grass, showed that they dated from winter.
In the evening the four of us witnessed the tragic end of a Lap-longspur. Pursued by a fierce Skua Gull, it unfortunately dashed out over the lake. In vain then it darted up and down, here and there, high and low; the Skua followed even more quickly. A second Skua came flying to help, but was not needed. With a falcon-like swoop, the pirate seized the Longspur in his bill and bore it away to be devoured at the nearest perch.
At 7.30 A. M., August 24, 1907, surrounded by scattering Caribou, we pushed off from our camp at Sand Hill Bay and began the return journey.
At Wolf-den Point we discovered a large and ancient wolf-den in the rocks; also abundance of winter sign of Musk-ox. That day we made forty miles and camped for the night on the Sand Hill Mountain in Tha-na-koie, the channel that joins Aylmer and Clinton-Colden. Here we were detained by high winds until the 28th.
This island is a favourite Caribou crossing, and Billy and Weeso had pitched their tents right on the place selected by the Caribou for their highway. Next day, while scanning the country from the top of the mount, I saw three Caribou trotting along. They swam the river and came toward me. As Billy and Weeso were in their tents having an afternoon nap, I thought it would be a good joke to stampede the Caribou on top of them, so waited behind a rock, intending to jump out as soon as they were past me. They followed the main trail at a trot, and I leaped out with "horrid yells" when they passed my rock, but now the unexpected happened. "In case of doubt take to the water" is Caribou wisdom, so, instead of dashing madly into the tents, they made three desperate down leaps and plunged into the deep water, then calmly swam for the other shore, a quarter of a mile away.
This island proved a good place for small mammals. Here Preble got our first specimen of the White Lemming. Large islands usually prove better for small mammals than the mainland. They have the same conditions to support life, but being moated by the water are usually without the larger predatory quadrupeds.
The great central inland of Clinton-Colden proved the best place of all for Groundsquirrels. Here we actually found them in colonies.
On the 29th and 30th we paddled and surveyed without ceasing and camped beyond the rapid at the exit of Clinton-Colden. The next afternoon we made the exit rapids of Casba Lake. Preble was preparing to portage them, but asked Weeso, "Can we run them?"
Weeso landed, walked to a view-point, took a squinting look and said, "Ugh!" (Yes). Preble rejoined, "All right! If he says he can, he surely can. That's the Indian of it. A white man takes risks; an Indian will not; if it is risky he'll go around." So we ran the rapids in safety.
Lighter each day, as the food was consumed, our elegant canoe went faster. When not detained by heavy seas 30 or 40 miles a day was our journey. On August 30 we made our last 6 miles in one hour and 6 1/2 minutes. On September 2, in spite of head-winds, we made 36 miles in 8 1/4 hours and in the evening we skimmed over the glassy surface of Artillery Lake, among its many beautiful islands and once more landed at our old ground—the camp in the Last Woods.
