On the 21st and 22d we had a continued struggle amongst heavy and close-packed ice until we reached Wager River Estuary, where we were detained all day by the immense quantities driving in with the flood and out again with the ebb tide, which ran at the rate of 7 or 8 miles an hour, forcing up the floes into large mounds, and grinding them against the rocks, with a noise resembling thunder. During the ebb tide the eddy currents once or twice brought in the ice with great force, which would have smashed our boats, as they lay in rather an exposed situation along the face of some steep rocks, had it not fortunately taken the ground before it reached us. During our stay, a meridian observation of the sun by artificial horizon gave latitude 65° 15' 36" N., variation 48° 13' W. 23d. There was a thin coat of ice on the water this morning, the temperature of which at midnight was 2° below the freezing point, that of the air 36°. As our position was far from safe, we were kept on the alert all night, and got under weigh at half-past three, for the purpose of finding some safer harbour. To get to a small bay a mile and a half to the west of us, we had more than once to pull for our lives, as the eddy currents already spoken of caused such sudden and uncertain movements among the ice that there was no telling on what side we were to expect it. With much difficulty we entered our harbour, and pulled half a mile up, so as to be safe from the ice, which we had reason to expect would come in with the flood. The latitude of our new anchorage was 65° 16' 8" N. This is the most northerly point on the south side of Wager River, which appears to be not very correctly laid down in the charts. The channel is not more than four or five miles broad. In the evening, being wearied with delay, as soon as the flood tide slacked, we pushed out into the stream, and when in mid-channel had the advantage of a fine breeze, which enabled us to stem the current that still ran at the rate of five miles an hour. The boats had some narrow escapes, and the Magnet received a severe squeeze, but fortunately sustained no injury, and we were soon in safety on the north side of the channel. 24th. Having pulled along shore all night, we cast anchor at half-past five this morning to take breakfast and give rest to the men. Our course since crossing Wager River had been among a number of small rocky islands, between which we had some difficulty in threading our way, but we did not see any signs of a second opening into Wager Bay, although a sharp look-out was kept. A light air of fair wind springing up, we got under weigh at a few minutes before 8, and stood on to the northward, the ebb tide again running with us. At mid-day the temperature of the air was 45°, water 32°.
