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?” asked 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 waterspouts, 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.
