On the 20th, there being a strong breeze from the N.N.E., with fog and rain, all favourable to the dispersion of the ice, that part of it which was immediately around the Hecla, and from which she had been artificially detached so long before, at length separated into pieces and floated away, carrying with it the collection of ashes and other rubbish which had been accumulating for the last ten months: so that the ship was now once more fairly riding at anchor, but with the ice still occupying the whole of the centre of the harbour, and within a few yards of her bows: the Griper had been set free in a similar manner a few days before. But it was only in that part of the harbour where the ships were lying that the ice had yet separated in this manner at so great a distance from the shore; a circumstance probably occasioned by the greater radiation of heat from the ships, and from the materials of various kinds which we had occasion to deposite upon the ice during the time of our equipment.
Lieutenant Liddon accompanied me in a boat down the west shore of the harbour to the southern point of the entrance, in order to sound along the edge of the ice, where we found from seven to fifteen feet water; the ice about the entrance appeared still very solid and compact, and not a single hole was at this time noticed through any of the pools upon its surface except one, which was made by a seal, and which discovered the thickness of the ice to be there between two and three feet.
There was a fresh breeze from the northeastward, with fine clear weather, on the 22d, which made the Hecla swing round into twenty feet water astern; and the ice, being now moveable in the harbour, came home towards the shore with this wind, but not so much as to put any considerable strain on the cable of either ship; and the holding-ground being excellent, there was nothing to apprehend for their security.
A fresh gale, which blew from the northward on the morning of the 23d, caused a great alteration in the appearance of the ice near the ships, but none whatever in that in the offing or at the mouth of the harbour, except that the shores were there more encumbered than before, owing to the quantity of pieces which were separated and driven down from the northward, so that our small boat could not succeed in getting along the shore.
