The equipment of the Hecla and Fury, and the loading of the William Harris transport, being completed, we began to move down the river from Deptford on the 8th of May, 1824, and on the 10th, by the assistance of the steamboat, the three ships had reached Northfleet, where they received their powder and their ordnance stores. Two days were here employed in fixing, under the superintendence of Mr. Barlow and Lieutenant Foster, the plate, invented by the former gentleman, for correcting the deviation of the compass produced by the attraction of the ship’s iron; and the continuance of strong easterly winds prevented our getting to the Nore till the 16th. During our stay at Northfleet the ships were visited by Viscount Melville, and the other Lords Commissioners of the Admiralty, who were pleased to approve of our general equipment and arrangements.

During our passage across the Atlantic in June, and afterwards on our way up Davis’s Strait, we threw overboard daily a strong copper cylinder, containing the usual papers, giving an account of our situation. We also took every opportunity afforded by light winds, to try the temperature of the sea at different depths, as compared with that at the surface.

I now determined, as the quickest and most secure mode of clearing the transport, to anchor at the Whale-fish Islands, rather than incur the risk of hampering and damaging her among the ice. Fresh gales and thick weather, however, prevented our doing so till the 26th, when we anchored at eight A.M., in seventeen fathoms, mooring the ships by hawsers to the rocks, and then immediately commenced our work. In the meantime the observatory and instruments were landed on a small island, called by the Danes Boat Island, where Lieutenant Foster and myself carried on the magnetic and other observations during the stay of the Expedition at this anchorage, of which a survey was also made.

Early on the morning of the 3rd of July, the whole of our stores being removed, and Lieutenant Pritchard having received his orders, together with our despatches and letters for England, the William Harris weighed with a light wind from the northward, and was towed out to sea by our boats. The day proving calm, we employed it in swinging the Hecla, in order to obtain the amount of the deviation of the magnetic needle, and to fix afresh the iron plate for correcting it. On the following morning, the wind being southerly, the pilots came on board, and the Hecla weighed to run through the north passage; in doing which she grounded on a rock lying directly in the channel, and having only thirteen feet upon it at low water, which our sounding boats had missed, and of which the pilot was ignorant. The tide being that of ebb we were unable to heave the ship off immediately, and at low water she had sewed three feet forward. It was not till half-past one P.M., that she floated, when it became necessary to drop her down between the rock and the shore with hawsers; after which we made sail, and being soon after joined by the Fury, which came out by the other channel, we stood round the islands to the northwards. This rock was not the only one found by our boats which may prove dangerous to ships going in and out of this harbour, and with which our pilots were unacquainted. Another was discovered by Mr. Head, about one-third of the distance across from Kron Prins Island to the opposite shore of the S.E. entrance, and has not more than eighteen feet water on it at low tide; it lies very much in the way of ships coming in at that channel, which is the most commonly used. The latitude of the island, on which the observations were made, called by the Danes Boat Island, is 74° 28′ 15″; its longitude by our chronometers, 53° 12′ 56″; the dip of the magnetic needle, 82° 53′ 66″; and the variation, 70° 23′ 57″ westerly. The time of high water, at new moon, on the 26th of June, was a quarter-past eight, the highest tides being the third and fourth after the conjunction, and the perpendicular rise seven feet and a half.

The ships standing in towards Lievely on the afternoon of the 5th, Lieutenant Graah very kindly came off to the Fury, which happened to be the nearest in shore, for the purpose of taking leave of us. On his quitting the ship a salute of ten guns was fired at Lievely, which we returned with an equal number; and I sent to Lieutenant Graah, by a canoe that came on board the Hecla, an account of the situation of the rocks we had discovered. Light northerly winds, together with the dull sailing of our now deeply laden ships, prevented our making much progress for several days, and kept us in the neighbourhood of numerous icebergs, which it is dangerous to approach when there is any swell. We counted from the deck, at one time, no less than one hundred and three of these immense bodies, some of them from one to two hundred feet in height above the sea; and it was necessary, in one or two instances, to tow the ships clear of them with the boats. We had occasion, about this time, to remark the more than usual frequency of fogs with a northerly wind, a circumstance from which the whalers are accustomed to augur a considerable extent of open water in that direction.

The ice soon beginning to close around us, our progress became so slow that, on the 17th, we saw a ship at the margin of the “pack,” and two more on the following day. We supposed these to be whalers, which, after trying to cross the ice to the northward, had returned to make the attempt in the present latitude; a supposition which our subsequent difficulties served to strengthen. From this time, indeed, the obstructions from the quantity, magnitude, and closeness of the ice, were such as to keep our people almost constantly employed in heaving, warping, or sawing through it; and yet with so little success that, at the close of the month of July, we had only penetrated seventy miles to the westward, or to the longitude of about 62° 10′. Here, while closely beset, on the 1st of August, we encountered a hard gale from the south-east, which pressing the ice together in every direction, by mass overlaying mass for hours together, the Hecla received several very awkward “nips,” and was once fairly laid on her broadside by a strain which must inevitably have crushed a vessel of ordinary strength. In such cases, the ice is forced under a ship’s bottom on one side, and on the other up her side, both powers thus acting in such a manner as to bring her on her “beam-ends.” This is, in fact, the most favourable manner in which a ship can receive the pressure, and would perhaps only occur with ice comparatively not very heavy, though sufficiently so, it is said, to have run completely over a ship in some extreme and fatal cases. With ice of still more formidable dimensions a vessel would probably, by an equal degree of pressure, be absolutely crushed, in consequence of the increased difficulty of sinking it on one side, and causing it to rise on the other.

Sept. 9th.—I shall doubtless be readily excused for not having entered in this journal a detailed narrative of the obstacles we met with, and of the unwearied exertions of the officers and men to overcome them, during the tedious eight weeks employed in crossing this barrier. I have avoided this detail because, while it might appear an endeavour to magnify ordinary difficulties, which it is our business to overcome rather than to discuss, I am convinced that no description of mine, nor even the minute formality of the log-book, could convey an adequate idea of the truth. The strain we constantly had occasion to heave on the hawsers, as springs to force the ships through the ice, was such as perhaps no ships ever before attempted; and by means of Phillips’s invaluable capstan, we often separated floes of such magnitude as must otherwise have baffled every effort. In doing this, it was next to impossible to avoid exposing the men to very great risk from the frequent breaking of the hawsers. On one occasion, three of the Hecla’s seamen were knocked down as instantaneously as by a gunshot by the sudden flying-out of an anchor; and a marine of the Fury suffered in a similar manner when working at the capstan; but, providentially, they all escaped with severe contusions. A more serious accident occurred in the breaking of the spindle of the Fury’s windlass, depriving her of the use of the windlass-end during the rest of the season.

The constant besetment of the ships, and our daily observations for latitude and longitude, afforded a favourable opportunity for ascertaining precisely the set of any currents by which the whole body of ice might be actuated. By attending very carefully to all the circumstances, it was evident that a daily set to the southward obtained, when the wind was northerly, differing in amount from two or three to eight or ten miles per day, according to the strength of the breeze; but a northerly current was equally apparent, and fully to the same amount, whenever the wind blew from the southward. A circumstance more remarkable than these, however, forced itself strongly upon my notice at this time, which was, that a westerly set was very frequently apparent, even against a fresh breeze blowing from that quarter. I mention the circumstance in this place, because I may hereafter have to offer a remark or two on this fact in connection with some others of a similar nature noticed elsewhere.

With respect to the dimensions of the ice through which we had now scrambled our way, principally by warping and towing a distance of between three and four hundred miles, I remarked that it for the most part increased, as well in the thickness as the extent of the floes, as we advanced westward about the parallel of 71°. During our subsequent progress to the north, we also met with some of enormous dimensions, several of the floes, to which we applied our hawsers and the power of the improved capstan, being at their margin more than twenty feet above the level of the sea, and over some of these we could not see from the mast-head. Upon the whole, however, the magnitude of the ice became somewhat less towards the north-west; and within thirty miles of that margin the masses were comparatively small, and their thickness much diminished. Bergs were in sight during the whole passage; but they were more numerous towards the middle of the “pack,” and rather the most so to the southward.
