The march to the cache was a very tedious one, but we took it leisurely, and got through with it in sixteen hours, to find our food unmolested. The repeated halts to rest the dogs gave me abundant leisure to search among the limestone cliffs for further fossil remains, and my exertions were rewarded with a valuable collection. It is, perhaps, too much to say that they are fossils of the Silurian era, from a hasty examination; but I think it more than probable. [Sidenote: THE SHORE-ICE.] I had also opportunity to measure some of the masses of ice which had been forced upon the shore. In many places these masses were crowded together, forming an almost impassable barrier. In other places the ice-foot had been torn through, and in one spot a table sixty feet in thickness and forty yards across had been crowded on the sloping shore, pushing up the loose, rocky _débris_ which lay at the base of the cliffs; and when the pack that had caused the disturbance had drifted away, this fragment was left with its lower edge above the tide. Around it were piled other masses; and, in order to pass it, we were obliged to climb far up the hill-side. Our next day's journey was even more difficult, as we became entangled among deep snow-drifts below Cape Frazer, and, on account of the rotten condition of the ice lining the shore, we could not take to the ice-fields. We tried twice, and came near paying dearly for the experiment. One of the teams got in bodily, and was extricated with difficulty; while, on the other occasion, I, acting in my usual capacity of pilot, saved myself from a cold bath with my ice-pole, which, plunging through the rotten ice and disappearing out of sight, gave me timely warning; so we put back again to the more secure land-ice. In the bay below Cape Napoleon we found, on the following day, secure footing, and reached Cape Hawks without difficulty, in two more marches. Thence we proceeded to follow our outward track through the hummocks. The sledges being now light, and Jensen having so far improved as to be able to walk, we experienced less embarrassment than on our outward journey; but the dogs were now in a very different condition, and lightness of load leveled not the hummocks and made not the steep places smooth, nor the ice less sharp, nor the snow-crusts less treacherous. The task was wearisome and exhausting to the last degree,--a hard struggle, destructive to the energies of men and dogs alike. Some snow had fallen, but, fortunately, the wind had drifted it from our tracks in many places, and we found our way to the small provision caches which we had left going north, and, luckily, they had all escaped the observation of the bears except one; but, having made a good march on the first day from Cape Hawks, we picked up the first cache we came to, and thus saved a day's food,--a piece of good fortune which we had not counted upon.
