Captain Clerke having determined, for the reasons assigned, to give up all farther attempts on the coast of America, and to make his last efforts in search of a passage on the coast of the opposite continent, we continued during the afternoon of the 21st of July, to steer to the W.N.W., through much loose ice. At ten at night, discovering the main body of it through the fog, right ahead, and almost close to us, and being unwilling to take a southerly course so long as we could possibly avoid it, we hauled our wind, which was easterly, and stood to the northward; but in an hour after, the weather clearing up, and finding ourselves surrounded by a compact field of ice on every side, except to the S.S.W., we tacked and stood on in that direction, in order to get clear of it. At noon of the 22d, our latitude, by observation, was 69 deg. 30', and longitude 187 deg. 30'. In the afternoon we again came up with the ice, which extended to the N.W. and S.W., and obliged us to continue our course to the southward, in order to weather it. It may be remarked, that, since the 8th of this month, we had twice traversed this sea, in lines nearly parallel with the run we had just now made; that in the first of those traverses we were not able to penetrate so far north, by eight or ten leagues, as in the second; and that in the last we had again found an united body of ice, generally about five leagues to the southward of its position in the preceding run. As this proves that the large compact fields of ice, which we saw, were moveable, or diminishing, at the same time, it does not leave any well-founded expectations of advancing much farther in the most favourable seasons.
