WE EXPLORE THE REEF
OCTOBER 31 to November 5. -- Our first proceeding on the morning of the 31st was to make the proposed tour of the reef, which is about a quarter of a mile long. With the aid of our sounding-lines we found that the water was deep, right up to the very rocks, and that no shelving shores prevented us coasting along them. There was not a shadow of doubt as to the rock being of purely volcanic origin, up- heaved by some mighty subterranean convulsion. It is formed of blocks of basalt, arranged in perfect order, of which the regular prisms give the whole mass the effect of being one gigantic crystal; and the remarkable transparency of the sea enabled us plainly to observe the curious shafts of the prismatic columns that support the marvelous sub- structure.
"This is indeed a singular island," said M. Letourneur;"evidently it is of quite recent origin."
"Yes, father," said Andre, "and I should think it has been caused by a phenomenon similar to those which pro- duced the Julia Island, off the coast of Sicily, or the group of the Santorini, in the Grecian Archipelago. One could almost fancy that it had been created expressly for the Chan- cellor to strand upon."
"It is very certain," I observed, "that some upheaving has lately taken place. This is by no means an unfrequented part of the Atlantic, so that it is not at all likely that it could have escaped the notice of sailors if it had been always in existence; yet it is not marked even in the most modern charts. We must try and explore it thoroughly and give future navigators the benefit of our observations."
"But, perhaps, it will disappear as it came," said Andre.
"You are no doubt aware, Mr. Kazallon, that these volcanic islands sometimes have a very transitory existence. Not im- possibly, by the time it gets marked upon the maps it may no longer be here."
"Never mind, my boy," answered his father, "it is bet- ter to give warning of a danger that does not exist than overlook one that does. I dare say the sailors will not grumble much, if they don't find a reef where we have marked one."
"No, I dare say not, father," said Andre, "and after all this island is very likely as firm as a continent. However, if it is to disappear, I expect Captain Curtis would be glad to see it take its departure as soon as possible after he has finished his repairs; it would save him a world of trouble in getting his ship afloat."
"Why, what a fellow you are, Andre!" I said, laugh- ing; "I believe you would like to rule Nature with a magic wand, first of all, you would call up a reef from the depth of the ocean to give the Chancellor time to extinguish her flames, and then you would make it disappear just that the ship might be free again."
Andre smiled; then, in a more serious tone, he expressed his gratitude for the timely help that had been vouchsafed us in our hour of need.
The more we examined the rocks that formed the base of the little island, the more we became convinced that its formation was quite recent. Not a mollusk, not a tuft of seaweed was found clinging to the sides of the rocks; not a germ had the wind carried to its surface, not a bird had taken refuge amid the crags upon its summits. To a lover of natural history, the spot did not yield a single point of interest; the geologist alone would find subject of study in the basaltic mass.
When we reached the southern point of the island I pro- posed that we should disembark. My companions readily assented, young Letourneur jocosely observing that if the little island was destined to vanish, it was quite right that it should first be visited by human beings. The boat was accordingly brought alongside, and we set foot upon the reef, and began to ascend the gradual slope that leads to its highest elevation.
The walking was not very rough, and as Andre could get along tolerably well without the assistance of an arm, he led the way, his father and I following close behind. A quarter of an hour sufficed to bring us to the loftiest point in the islet, when we seated ourselves on the basaltic prism that crowned its summit.
Andre took a sketch-book from his pocket, and proceeded to make a drawing of the reef. Scarcely had he completed the outline when his father exclaimed:
"Why, Andre, you have drawn a ham!"
"Something uncommonly like it, I confess," replied Andre. "I think we had better ask Captain Curtis to let us call our island Ham Rock."
