Another reason there was why it would have been the best place for me. Had I succeeded in mounting up there before nightfall, some one upon the shore might have noticed me, and then the adventure would have ended without all this peril. I even thought at the time of those things, and while clambering up the shaft entertained hopes that some one might observe me. I afterwards learned that some one did--more than one-- idlers along shore; but not knowing who it was, and very naturally believing that some Sabbath-breaking boys had gone out to the reef to amuse themselves--part of that amusement being to "swarm" up the signal-staff--I was set down as one of those, and no farther notice was taken of me. I could not have continued to go up the staff. It speedily tired me out; besides, as soon as I perceived the necessity for erecting the platform, I needed every second of the time that was left me for that work. All the above thoughts did not pass through my mind while I was in the water struggling back to the staff, though some of them did. I thought of the impossibility of climbing up above the barrel--that was clear to me; and I thought also of what I should do when I reached the post, and that was not clear to me. I should be able to lay hold upon the staff, as I had done before, but how I was to retain my hold was the unsolved problem. And it remained so, till I had got up and seized the staff, and indeed for a good while after. Well, I reached the pole at length, after a great deal of buffetting, having the wind and tide, and even the rain in my teeth. But I reached it, and flung my arms around it as if it had been some dear old friend. Nor was it aught else. Had it not been for that brave stick, I might as well have stayed at the bottom. Having clutched hold of it, I felt for some moments almost as if I had been saved. I experienced no great difficulty in keeping my limbs afloat so long as I had such a support for my arms, though the work was irksome enough. Had the sea been perfectly calm I could have stood it for a long time; perhaps till the tide had gone out again, and this would have been all I could have desired. But the sea was not calm, and that altered the case. There had been a short lull with the smoother sea just as I returned to the staff, and even this was a fortunate circumstance, as it gave me time to rest and recover my breath. Only a short respite it was, and then came wind and rain and rough seas--rougher than ever. I was first lifted up nearly to the barrel, and then let down again with a pitch, and then for some minutes was kept swinging about--the staff serving as a pivot--like some wonderful acrobat performing his feats in a gymnasium.
