This was an anxious time. So long as they had felt that they had plenty of sea-room the little party of adventurers had not yet recognized any danger which they thought sufficient to deter them from farther progress; but if the ice and the bottom were coming together, what could they do? It was possible, by means of explosives they carried, to shatter the ice above them; but action of this kind had not been contemplated unless they should find themselves at the pole and still shut in by ice. They did not wish to get out into the open air at the point where they found themselves; and, moreover, it would not have been safe to explode their great bombs in such shallow water. A consultation was held, and it was agreed that the best thing to do was to diverge from the course they had steadily maintained, and try to find a deeper channel leading to the north. Accordingly they steered eastward. It was not long before they found that they had judged wisely; the bottom descended far out of the reach of their electric lead, and they were enabled to keep a safe distance below the overhanging ice. “I feel sure,” said Mr. Gibbs, “that we came near running against some outreaching portion of the main Western Continent, and now we have got to look out for the foundations of Greenland's icy mountains.” He spoke cheerily, for he wished to encourage his companions, but there was a very anxious look upon his face when he was not speaking to any one. The next day every one was anxious, whether he spoke or was silent. The bottom was rising again, and the Dipsey was obliged to sail nearer and nearer to the ice above. Between two dangers, constricted and trammelled as they were, none of them could help feeling the terrors of their position, and if it had not been for the encouraging messages which continually came to them from Sardis, they might not have been able to keep up brave hearts. After two days of most cautious progress, during which the water became steadily shallower and shallower, it was discovered that the ice above, which they were now obliged to approach much more closely than they had ever done before, was comparatively thin, and broken in many places. Great cracks could be seen in it here and there, and movements could be discerned indicating that it was a floe, or floating mass of ice. If that were the case, it was not impossible that they were now nearing the edge of the ice under which they had so long been sailing, and that beyond them was the open water. If they could reach that, and find it the unobstructed sea which was supposed to exist at this end of the earth's axis, their expedition was a success. At that moment they were less than one hundred miles from the pole.
