I soon touched with my hands the interesting piece of wood, and felt as proud at that moment as if it had been the North Pole itself, and I its discoverer. I was not a little surprised at its dimensions, and how much the distance had hitherto deceived me. Viewed from the shore, it looked no bigger than the shaft of a hoe or a hay-fork, and the knob at the top about equal to a fair-sized turnip. No wonder I was a bit astonished to find the staff as thick, and thicker, than my thigh, and the top full larger than my whole body! In fact, it was neither more nor less than a barrel or cask of nine gallons. It was set upon end, the top of the staff being wedged into a hole in the bottom, thus holding it firmly. It was painted white, though this I knew before, for often had I viewed it glistening under the sun, while the shaft below was a dark colour. It may have been black at one time, and had grown discoloured by the weather and the spray of the stormy water, that often lashed all around it, even up to the barrel at the top. Its height, too, I had miscalculated as much as its thickness. From the land it appeared no taller than an ordinary man; but looking up to it from the shoal, it towered above me like the mast of a sloop. It could not have been less than twelve feet--yes, twelve it was at the very least. I was equally surprised at the extent of ground that I found above water. I had long fancied that my islet was only a pole or so in size, but I now perceived it was a hundred times that--an acre, or very near. Most of the surface was covered with loose rocks, or "boulders," from the size of small pebbles to pieces as big as a man's body, and there were other rocks still larger, but these I perceived were not loose, but half buried, and fast as rocks could be. They were only the projecting ends of great masses that formed the strength of the reef. All, both large ones and small ones, were coated over with a black, slimy substance, and here and there great beds of seaweed, of different kinds, among which I recognised some sorts that were usually cast up on our beach, and passed by the name of "sea-wreck." With these I had already formed a most intimate acquaintance, for more than one hard day's work had I done in helping to spread them over my uncle's land, where they were used as manure for potatoes. After having satisfied myself with a survey of the tall signal-staff, and guessed at the dimensions of the barrel at the top, I turned away from it, and commenced wandering over the reef. This I did to see if I could find some curious shell or other object that would be worth carrying back with me--something to keep as a memento of this great and hitherto pleasant excursion.
