The wind being from the S.S.W. during the night of the 30th, served to close the lane of water which had appeared in the offing the preceding day, which we considered a favourable circumstance, as showing that the external mass of ice was in motion. In the course of the day, the wind shifting to the W.N.W., we once more discovered a small opening between the old and young floes, and at eleven P.M., the whole body of the ice in the harbour was perceived to be moving slowly out to the southeastward, breaking away, for the first time, at the points which form the entrance of the harbour. This sudden and unexpected change rendering it probable that we should at length be released, I sent to Captain Sabine, who had been desirous of continuing his observations on the pendulum to the last moment, to request that he would have the clocks ready for embarcation at an early hour in the morning. CHAPTER X. Leave Winter Harbour.--Flattering Appearance of the Sea to the Westward.--Stopped by the Ice near Cape Hay.--Farther Progress to the Longitude of 113° 48' 22.5", being the Westernmost Meridian hitherto reached in the Polar Sea, to the North of America.--Banks's Land discovered.--Increased Extent and Dimensions of the Ice.--Return to the Eastward, to endeavour to penetrate the Ice to the Southward.--Re-enter Barrow's Strait, and Survey its South Coast.--Pass through Sir James Lancaster's Sound on our Return to England. The wind still blowing fresh from the northward and westward, the ice continued to drift out slowly from the harbour, till, at eight A.M., August 1st, it had left the whole space between the ships and Cape Hearne completely clear, and at eleven o'clock there appeared to be water round the hummocks of ice which lie aground off that point. In the mean time, our boats were employed in embarking the clocks, tents, and observatory, while I sounded the entrance of the harbour in order to complete the survey, which no opportunity had offered of doing before this time. At one P.M., having got everything on board, and the ice appearing to be still leaving the shore, we weighed, and ran out of Winter Harbour, in which we had actually, as had been predicted, passed ten whole months, and a part of the two remaining ones, September and August.
