“Bosh!” he declared. “Why you can take splendid headers from the middle rock there. Oh—good Lord!”

The exclamation was forcible, and to it was appended a sort of amazed gasp from all who saw. And in truth I was not the least amazed of the lot. For there was a disturbance in the depths of the pool. One glimpse of something smooth, and sinuous, and shiny—something huge, and certainly horrible—was all we obtained, as not even breaking the surface to which it rose, the thing, whatever it might be—sank away from sight.

“What was it?”

“Can’t say for certain,” I said, replying to the general query. “It didn’t come up high enough to take any shape at all. It might have been a big python lying at the bottom of the hole, and concluding it had lain there long enough came up, when the sight of us scared it down again. I’m pretty sure it wasn’t a crocodile.”

“Tell you what, Glanton. You don’t catch me taking any more headers in there again in a hurry,” said Falkner. “Ugh! If we’d only known!”

“There is prestige in the unknown,” I said. “It may be something quite harmless—some big lizard, or a harmless snake.”

“Well it’s dashed odd we should just have been talking of that very sort of thing,” said the Major. “Let’s keep quiet now and watch, and see if it comes up again.”

We did, but nothing came of it. Indeed if I alone had seen the thing I should have distrusted my senses, should have thought my imagination was playing me false. But they had all seen it.

“I shall come down here again with the rifle and watch for an hour or two a day,” said Falkner. “Or how would it be to try bait for the beast, whatever it is—eh, Glanton?”

“Well you might try to-morrow. Otherwise there isn’t much time,” I answered. “We trek on Wednesday, remember.”
