"I was just going to remark about that," the patrol leader added. "If all of a sudden we found the boat, and had been talking loud, or laughing, the chances are the game would give us the slip. So after this whoever is doing the pushing try not to splash more than you can help; and when you talk do it in whispers."

Perhaps all this mystery added to the pleasure of such a fellow as Lil Artha; at least his eyes were sparkling much more than their wont as he continued to ply his pole with the air of a Venetian gondolier along the Grand Canal.

Once, however, he must have rammed it too hard into the yielding ooze, for when he tried to pull it out there was considerable resistance. Lil Artha managed to stop the moving skiff in time to save himself; even then he might have been pulled overboard only that watchful Mark, anticipating something of the sort, threw his arms around the long legs of the pusher, and held on grimly until the pole could be extricated.

An hour, two of them had slipped by since parting from Johnny Spreen. They were now in the heart of the swamp. All around them lay a solemn silence broken only by the splash of a bullfrog leaping from a bank, the gurgle of some water snake or the solemn croak of a bittern fishing near by, followed by the flap of its wings as it flew away, alarmed by their approach.

All of the boys were more or less impressed by this strange silence. It seemed as though some heavy weight were pressing down upon them. Toby even whispered to one of his mates that it could hardly be worse if they were passing through a country graveyard at midnight.

At the same time, all of them being bright, wide-awake fellows, there were plenty of interesting things continually cropping up to arouse their interest as scouts. Every minute or so someone was calling attention to this or that thing, though never forgetting the need of caution.

If at any time a voice was raised more than Elmer deemed wise, a single "hist" from his lips caused the speaker to moderate his tones instantly.

By now they were not so much concerned about where they went as the possibility of finding the missing skiff. Eager eyes were ever on the alert. A number of times Lil Artha, or it might be Toby or Chatz, felt a sudden thrill as some object caught their attention ahead, which at first glance seemed to open up great possibilities. Then as they moved closer and a better chance came to investigate, deep disappointment and chagrin would follow; for after all it turned out to be only the end of a log, or some such simple thing, and not the stern of the old skiff at all.

Elmer happened to be a little ahead of the other boat at the time Chatz, consulting his nickel watch, found it was just ten o'clock. When he showed this to Toby the latter grinned as though very much pleased.

"I nominated ten, didn't I, Chatz?" he remarked in a low tone; "when you asked me to take a squint up at the sun, and say what the hour might be?"
