Another apprehension troubled me: my cairn was far too loosely put together. I had not attempted to make any building of the thing; there was not time for that. The stones had been hurled or huddled on top of one another, just as they dropped out of my hands; and as I set my feet upon them I felt they were far from firm. What if they should not prove enough so to resist the current of the returning tide, or the lashing of the waves? Should they not, then indeed I had laboured in vain. Should they fall, I must fall with them, never again to rise!
No wonder that this added another to the many doubts I had to endure; and as I thought upon such a mischance occurring, I again looked eagerly outward, and ran my eyes in every direction over the surface of the bay, only, as on every other occasion, to meet with sad disappointment.
For a long time I remained in the exact position I had first assumed—that is with my arm thrown round the signal-staff, and hugging it as if it were a dear friend. True, it was the only friend I had then; but for it an attempt to have built the cairn would have been vain. Even could I have raised it to the full height, it is neither likely that it would have stood the water or that I could have held my position upon it. Without the staff to hold on to, I could not have balanced my body on its top.
This position, then, I kept, almost without moving a muscle of my body. I dreaded even to change my feet from one stone to another lest the movement might shake the pile and cause it to tumble down, and I knew that if once down, there would be no chance to build it up again. The time was past for that. The water all around the base of the staff was now beyond my depth. I could not have moved a step without swimming.
I passed most of the time in gazing over the water; though I did not move my body, I kept constantly turning my neck. Now looking before, then behind, then to both sides, and the next moment repeating these observations, until I had scanned the surface for the fiftieth time, without sight of boat or ship to reward me. At intervals I watched the returning tide, and the huge waves as they rolled towards me over the reef, coming home from their far wanderings. They appeared angry, and growled at me as they passed, as if to chide and scold me for being there. What was I, weak mortal, doing in this their own peculiar home—this ground that was the chosen spot for their wild play? I even fancied that they talked to me. I grew dizzy as I watched them, and felt as if I should swoon away and melt into their dark flood.
I saw them rising higher and higher, until they swept over the top of my cairn, and covered my feet resting on it; higher still and yet higher, till I felt them lipping against my knees. O! when will they stay? When will they cease to come on?
Not yet—not yet—higher! higher! till I stand up to the waist in the briny flood, and even above that the spray washes around me—against my face—over my shoulders—into my mouth, and eyes, and ears—half-stifling me, half-drowning me! O merciful Father!
The water had reached its height, and I was almost overwhelmed by it; but with desperate tenacity of life I held out, closely clinging to the signal-shaft. For a very long time I held on, and, had no change occurred, I might have been able to keep my place till the morning; but a change was near, and one that placed me in greater peril than ever.
Night came on; and, as if this had been a signal for my destruction, the wind increased almost to a gale. The clouds had been scowling throughout the twilight, as if threatening rain, which now fell in torrents—the wind, as it were, bringing the rain along with it. I perceived that the waves were every moment rising higher, and one or two large ones now swept almost over me. So great was their strength that I was scarcely able to resist it, and came very near being swept away.
I was now full of fear. I saw that should the breakers grow larger, I could not hold out against them, but must succumb. Even as they were, it was doubtful whether my strength would hold out.
