(Looking down the river from Von Wilczek Valley).

From Von Wilczek valley to old Fort Selkirk is but a little over twenty miles; and the river is so full of islands in many places that for long stretches we could hardly see both banks at a time, while it was nothing unusual to have both out of sight at points where the islands were most numerous. This cluster of islands (named after Colonel Ingersoll, of Washington), is, I think, situated in the bed of one of the ancient lakes of which I have spoken, although the opinion of a professional geologist would be needed to settle such a matter.

At 3 P.M. we reached the site of old Fort Selkirk. All our maps, some half a dozen in number, except one, had placed the site of Selkirk at the junction of the Pelly and Yukon between the two, the single exception noted placing it on the north bank of the Pelly where the streams unite. Noticing this discrepancy I asked Indianne for an explanation, and he told me that neither was correct, but that the chimneys of the old ruins would be found on the south side of the river about a mile below the junction, and I found him correct, the chimneys being visible fully a mile before we reached them. Here we were on land familiar to the footsteps of white men who had made maps and charts, that rough and rude though they were, were still entitled to respect, and accordingly at this point I considered that my explorations had ceased, although my surveys were continued to the mouth of the river; making the distinction that the first survey only is an exploration, a distinction which I believe is rapidly coming into vogue. Altogether on the Yukon River, this far, there had been taken thirty-four astronomical observations, four hundred and twenty-five with the prismatic compass, and two for variation of compass. I have no doubt that these are sufficiently accurate at least for all practical purposes of geographical exploration in this country, until more exact surveys are demanded by the opening of some industry or commerce, should that time ever come. The total length of this portion of the river just traversed from Haines Mission to Selkirk was five hundred and thirty-nine miles; the total length of the raft journey from its commencement at the camp on Lake Lindeman being four hundred and eighty-seven miles; while we had sailed and "tracked" and rowed across seven lakes for a distance aggregating one hundred and thirty-four miles.
