I could not remain where I was. In a few seconds my strength gave way, and I was forced to slide down to the base of the staff.
I tried again, with no better success; and then again, with a similar result. It was to no purpose. Stretch my arms as I would, and wriggle my limbs as I might, I could not get my body higher than the point where the staff was set, and could only extend my hand half-way up the rounded swell of the cask. Of course I could not keep there, as there was nothing to rest my weight upon, and I was forced to glide back to the ground.
It was with a feeling of renewed alarm, then, that I made this discovery, but I did not as before yield myself up to despair. Perhaps my wits were quickened by the peril that was fast approaching me. At all events, I kept my senses about me, and set to considering what was best to be done.
If I had only been in possession of a knife, I might have cut notches in the pole high up, and on these rested my feet; but I had no knife—nothing to make notches with—unless I had eaten them out with my teeth. Verily I was in a difficult dilemma.
All at once, however, a bright thought came to my relief. Why might I not raise a resting-place from below? Why not make a platform by building stones around the post, until they had reached above watermark, and then stand upon these? The very thing itself. A few stones, I had noticed already, were piled around the base, no doubt placed there to make the staff more firm. It would only be to bring up more stones, build them into a cairn, and then get on the top of them!
Delighted with this new project of safety, I lost not a moment in setting about carrying it into effect. There were plenty of loose boulders lying over the reef, and I supposed that in a few minutes I could heap up enough of them to serve the purpose; but I had not worked long before I perceived that the job would occupy me longer than I had anticipated. The stones were slippery, and this hindered me greatly in carrying them—some were too heavy for me, and others that I had supposed to be loose, I found to be half buried in sand, and held so fast that I could not draw them out.
Notwithstanding these impediments, I worked on with all the strength and energy I could command. I knew that in time I could raise the cairn as high as required, but time had now become the all-engrossing subject of my thoughts.
The tide had long since turned; it was rising; slowly and continuously it was lipping nearer and nearer—slowly but with certainty was it coming; and I perceived all this!
I had many a fall, as I scrambled to and fro; and my knees were bleeding from contact with the hard stones; but these were not matters to grieve about, nor was it a time to give way to hardships, however painful to endure. A far greater hardship threatened—the loss of life itself—and I needed no urging to make me persevere with my work.
I had raised the pile up to the height of my head before the tide had yet risen over the rocks, but I knew that this would not be high enough. Two feet more was wanted to bring the top of my cairn on a level with high-water mark; and to accomplish this I slaved away without thinking of a moment’s rest. The work as it went on became more difficult. The loose stones that lay near had all been used, and I was obliged to go far out on the reef to procure others. This led to a great many severe falls, in which both my hands and knees were badly bruised; besides, it prevented me from making rapid progress. There was another cause that delayed me. At the height of four feet the pile was on a level with the crown of my head, and it was with difficulty I could place the stones higher up. Each one occupied me for minutes, and sometimes a heavy boulder which I had succeeded in getting up, would roll back again, endangering my limbs in its fall.
