[Sidenote: Thursday, 6th.] The continuance of stormy weather detained us until two P.M. of the 9th, when the rain ceasing, we embarked. After passing through the expansion of the river near the west extreme of Halkett Island, we turned into the narrower and more winding channel, between Colvill Island and the main. A fog coming on at eight P.M. we encamped, in latitude 68 degrees 48 minutes N., longitude 136 degrees 4 minutes W.; temperature of the air 42 degrees, that of the water being 47 degrees in the middle of the stream. Several of the glaucous gulls were seen, and this circumstance, as well as a line of bright cloud to the N.W. resembling the ice-blink, convinced us that the sea was not far off. A rein-deer appearing near the encampment, two men were sent after it, who returned unsuccessful. Augustus obtained a goose for supper. Many geese, swans, and ducks, had been seen on the marshy shores of the island in the course of the day. [Sidenote: Friday, 7th.] The night was cold, and at daylight on the 7th the thermometer indicated 36 degrees. Embarking at four A.M. we sailed down the river for two hours, when our progress was arrested by the shallowness of the water. Having endeavoured, without effect, to drag the boats over the flat, we remounted the stream to examine an opening to the westward, which we had passed. On reaching the opening we found the current setting through it into the Mackenzie, by which we knew that it could not afford a passage to the sea, but we pulled up it a little way, in the hope of obtaining a view over the surrounding low grounds from the top of an Esquimaux house which we saw before us. A low fog, which had prevailed all the morning, cleared away, and we discovered that the stream we had now ascended issued from a chain of lakes lying betwixt us and the western hills, which were about six miles distant, the whole intervening country between the hills and the Mackenzie being flat.
