We were now fairly started.Half a mile's walk conveyed us round a bend in the land which shut out our bower from view, and for some time we advanced at a brisk pace without speaking, though our eyes were not idle, but noted everything, in the woods, on the shore, or in the sea, that was interesting.After passing the ridge of land that formed one side of our valley - the Valley of the Wreck - we beheld another small vale lying before us in all the luxuriant loveliness of tropical vegetation.We had, indeed, seen it before from the mountain-top, but we had no idea that it would turn out to be so much more lovely when we were close to it.We were about to commence the exploration of this valley, when Peterkin stopped us, and directed our attention to a very remarkable appearance in advance along the shore.
"What's yon, think you?" said he, levelling his spear, as if he expected an immediate attack from the object in question, though it was full half a mile distant.
As he spoke, there appeared a white column above the rocks, as if of steam or spray.It rose upwards to a height of several feet, and then disappeared.Had this been near the sea, we would not have been so greatly surprised, as it might in that case have been the surf, for at this part of the coast the coral reef approached so near to the island that in some parts it almost joined it.
There was therefore no lagoon between, and the heavy surf of the ocean beat almost up to the rocks.But this white column appeared about fifty yards inland.The rocks at the place were rugged, and they stretched across the sandy beach into the sea.Scarce had we ceased expressing our surprise at this sight, when another column flew upwards for a few seconds, not far from the spot where the first had been seen, and disappeared; and so, at long irregular intervals, these strange sights recurred.We were now quite sure that the columns were watery or composed of spray, but what caused them we could not guess, so we determined to go and see.
In a few minutes we gained the spot, which was very rugged and precipitous, and, moreover, quite damp with the falling of the spray.We had much ado to pass over dry-shod.The ground also was full of holes here and there.Now, while we stood anxiously waiting for the re-appearance of these water-spouts, we heard a low, rumbling sound near us, which quickly increased to a gargling and hissing noise, and a moment afterwards a thick spout of water burst upwards from a hole in the rock, and spouted into the air with much violence, and so close to where Jack and I were standing that it nearly touched us.We sprang to one side, but not before a cloud of spray descended, and drenched us both to the skin.
Peterkin, who was standing farther off, escaped with a few drops, and burst into an uncontrollable fit of laughter on beholding our miserable plight.
"Mind your eye!" he shouted eagerly, "there goes another!" The words were scarcely out of his mouth when there came up a spout from another hole, which served us exactly in the same manner as before.
Peterkin now shrieked with laughter; but his merriment was abruptly put a stop to by the gurgling noise occurring close to where he stood.
"Where'll it spout this time, I wonder?" he said, looking about with some anxiety, and preparing to run.Suddenly there came a loud hiss or snort; a fierce spout of water burst up between Peterkin's legs, blew him off his feet, enveloped him in its spray, and hurled him to the ground.He fell with so much violence that we feared he must have broken some of his bones, and ran anxiously to his assistance; but fortunately he had fallen on a clump of tangled herbage, in which he lay sprawling in a most deplorable condition.
It was now our turn to laugh; but as we were not yet quite sure that he was unhurt, and as we knew not when or where the next spout might arise, we assisted him hastily to jump up and hurry from the spot.
I may here add, that although I am quite certain that the spout of water was very strong, and that it blew Peterkin completely off his legs, I am not quite certain of the exact height to which it lifted him, being somewhat startled by the event, and blinded partially by the spray, so that my power of observation was somewhat impaired for the moment.
"What's to be done now?" inquired Peterkin ruefully.
"Make a fire, lad, and dry ourselves," replied Jack.
"And here is material ready to our hand," said I, picking up a dried branch of a tree, as we hurried up to the woods.
In about an hour after this mishap our clothes were again dried.
While they were hanging up before the fire, we walked down to the beach, and soon observed that these curious spouts took place immediately after the fall of a huge wave, never before it; and, moreover, that the spouts did not take place excepting when the billow was an extremely large one.From this we concluded that there must be a subterraneous channel in the rock into which the water was driven by the larger waves, and finding no way of escape except through these small holes, was thus forced up violently through them.At any rate, we could not conceive any other reason for these strange water-spouts, and as this seemed a very simple and probable one, we forthwith adopted it.
"I say, Ralph, what's that in the water? is it a shark?" said Jack, just as we were about to quit the place.
I immediately ran to the overhanging ledge of rock, from which he was looking down into the sea, and bent over it.There I saw a very faint pale object of a greenish colour, which seemed to move slightly while I looked at it.
"It's like a fish of some sort," said I.
"Hallo, Peterkin!" cried Jack, "fetch your spear; here's work for it."But when we tried to reach the object, the spear proved to be too short.
"There, now," said Peterkin with a sneer, "you were always telling me it was too long."Jack now drove the spear forcibly towards the object, and let go his hold; but, although it seemed to be well aimed, he must have missed, for the handle soon rose again; and when the spear was drawn up, there was the pale green object in exactly the same spot, slowly moving its tail.
"Very odd," said Jack.
But although it was undoubtedly very odd, and, although Jack and all of us plunged the spear at it repeatedly, we could neither hit it nor drive it away, so we were compelled to continue our journey without discovering what it was.I was very much perplexed at this strange appearance in the water, and could not get it out of my mind for a long time afterwards.However, I quieted myself by resolving that I would pay a visit to it again at some more convenient season.
