"What on earth was that?" cried Rod.

But there was nothing further to be seen. A few bubbles came struggling up through the water, but the creature had gone, and so had the fish.

"It couldn't have been that fisher-cat," said Rod.

"No, indeed! Who ever heard of a fisher-cat, or any other cat, swimming ten rods under water!"

"But he is gone from the stump."

"Well, let him go. That wasn't him."

"What was it, then?"

That was a question easier asked than answered. We were fairly "stuck," as Rod expressed it, and stood staring into the hole. Suddenly there was a wavy motion, deep down, below the surface, and we saw the creature shoot back, by the hole, with the fish in his mouth. We had just a dim, refractive glimpse, and he had passed, going toward the shore. We looked in that direction, and a few seconds after, saw a flat, black head pop up a moment into sight from the open water, and, then it disappeared. We watched for some minutes, but it did not come up again.

"Rather a strange performance, anyhow," muttered Rod.

"But let's go round to the shore, and see if we can find the fisher."
