banks at the bends. A few miles from where Akie River enters is a network of islands, bars, and channels; in one place the river-bed being half a mile wide. Twenty miles above the canyon the stream again gathers in one channel, islands being occasional to Russel Creek, 72 miles above Grahame. Thence for 13 miles to Paul Creek the river has several large loops. The valley narrows to 3 miles. Above Paul Creek the stream skirts the mountains on the east side. Kwadacha River enters 96 miles from Grahame and Fox River 3 miles beyond, a small stream which occupies the north-westerly trend of the main valley; the Finlay here abruptly leaving this valley and coming from the west in a narrow gap between mountains until after passing the foot of Prairie Mountain, where the river is in a wide valley paralleling its original course. At 115 miles from Grahame the mountains close together at Long Canyon,5 miles in length, in two places in which the river is cut into narrower channels 30 and 60 feet wide. Bad water occurs for half a mile and canoes are lined up at low water, and at high water a portage is necessary. There is no portage-trail. For 5 miles above the canyon the river is swift, shallow, and broken by riffles. It has average width of 150 yards. At 125 miles from Grahame the stream turns abruptly from the north, in Cascade Canyon, the main valley continuing westward and meeting the Finlay again above the canyon, which is full of shallow rocky rapids and 2 miles up has a 25-foot drop in a series of wild cascades. Above the gorge-like canyon the valley is again wide, with an eastern continua- tion across to Fox River, in places having width of 3 miles, but excepting a couple of square miles of meadow and bottom north-east of Cascade Canyon and small bottoms in loops the land is not of value, being stony and gravelly and denuded of soil by forest fires which have swept the whole upper valley. From Porcupine Creek the river is a succession of shallow, boulder-strewn rapids. Above Thudaka River, a mountain torrent, the river comes from the south-east, and after a couple of small cascades falls through Reef Canyon, 2% miles long, into vertical walls. Above Reef Canyon the rough country through which the river has cut its way changes to alluvial flats occupying an ancient lake-basin; the river, widened to 300 yards, having sluggish flow and the bed is reed-choked and shores muddy. On either hand are large flats thickly covered with willows and full of beaver meadows and ponds for a mile from the river. This lake-like expanse is about 5 miles long and lies north and south. At the head the current again becomes perceptible and the river is soon a swift-flowing stream full of gravel-bars and islands between high mountains. Twelve miles above Reef Canyon Thudegade River enters from the west and 2 miles farther Delta Creek from the east. A horse-trail from Lake Thutade leaves the Finlay here, follows up Delta Creek, crosses the summit and down Bower Creek, reaching the Finlay again a mile below Long Canyon. At Delta Creek the Finlay is 125 feet, running swiftly over a gravel bottom. It continues swift and full of bars and islands until in latitude 57° 17’, 165 miles from Grahame, Thirty-four.
