But if not a cat, what was making that angry snarling?

Paul knew next to nothing about balloons, but he felt pretty sure that even the escaping of gas could hardly produce such a sound—it might pass through a rent in the silk with a sharp hiss, but he could plainly catch something more than that.

And then his foot struck solid ground; with a sigh of relief he drew himself up, and turned to give a hand to Seth, next in line, if it was needed.

So they all came ashore, so to speak, and delighted to feel able to stand in a comfortable position once more.

No time now for stretching or dancing, with that ugly snarling growing constantly deeper, and more angry in volume. Forward was the word, and Paul somehow felt glad that they gripped those handy staves, tried and true, with which every scout in course of time becomes quite adept. They would come in good play should there be any necessity for prompt action.

"Follow me, everybody," said Paul, as he started off.

"Count on us to back you up!" Seth declared, from which remark the scoutmaster understood that by now the others must have caught those suspicious sounds, and were trying to figure out what they stood for.

It seemed as if with every forward step he took, Paul could catch them more and more plainly. Nor was the snarling sound alone; now he believed he caught a rustling of dead leaves, and something that might be likened to low muttered words, as though the speaker were being hard pressed, and had little breath to spare.

Then, as he pushed through the last fringe of bushes that interfered with his view, Paul found himself looking upon the cause of all these queer noises.
