“All right, old fellow,” cried his companion. “There, say no more.”
The sun was growing intensely hot now, as Smith shouldered the ladder, and they once more started up the slope, which rapidly grew steeper, so stiff indeed was the ascent that Oliver, who led, after trying the zigzag approach and finding it too difficult, bore away to the east, making the ascent more gradual, and as if the intention was to form a corkscrew-like path round the upper part of the mountain.
“We’ve done wrong,” he said, after a couple of hours’ struggle upwards, “we ought to have gone to the west, and then by this time we should have been in the shade instead of roasting here.”
They had paused to have a bit of lunch and rest, for the heat was intense now, and the cracks or rifts in the mountain slope more frequent, but they were not half the width of that which had been just crossed, and as the party had grown more confident they took each in turn readily enough.
“We must make the best of it now,” said Panton, “and I can’t help thinking that we are doing right.”
“Why?” asked Drew.
“It seems to me that it would be impossible to get up to the crater edge on account of these horrible hot gases which rise from the cracks. We had better aim at getting round to the other side, and looking out from there as high up as we can climb. We shall know then whether the place is an island. What do you say, Lane?”
“The same as you do. I’ve been thinking so for an hour. You see, the ashes get looser as we climb higher, and the mountain steeper. What looked easy enough from below proves to be difficult in the extreme, and if we go much higher I feel sure that we shall set loose a regular avalanche and begin sliding down altogether.”
A quarter of an hour later they started off again somewhat refreshed, but suffering terribly from the volcanic heat radiating from the ashes as well as from that from the sun, but they pressed on steadily, rising higher and gradually getting round the north slope, though the farther they tramped over the yielding ashes, the more they were impressed by the fact that the mountain was ten times greater than they had imagined it from below.
At last, late on in the afternoon, Oliver stopped short.
