Meanwhile the sound had ceased, and was forgotten by the time they were all on board once more, the rope which had moored them to a tree being cast off.

“Now, my lads, away with you!” growled Shaddy, and the oars dropped among the lily leaves with a splash, startling quite a shoal of fish on one side and a large reptile on the other, which raised quite a wave as it dashed off with a few powerful strokes of its tail for deeper water.

They were about fifty yards from the shore, when Shaddy suddenly laid his hand upon Rob’s shoulder and pointed back to the place they had just left.

“See that, my lad?”

“No. What?” cried Rob hastily. “Bird? lizard?”

“Nay; look again.”

Rob swept the shore eagerly, and the next moment his eyes lit upon something tawny standing in a shady spot, half hidden by the leaves.

“The puma!” he cried excitedly, and as the words left his lips the animal made one bound into the undergrowth near the trees, and was gone.

“Or another, one, Rob,” said Brazier. “It is hardly likely to be the same. There are plenty about, I suppose, Naylor?”

“Oh yes, sir. Can’t say as they swarm, but they’re pootty plentiful, and as much like each other as peas in a pod.”
