"I see the mouth!" exclaimed Phil Towns, who had very keen eyesight. "Just look on the other side of that crooked tree, and you'll glimpse a little bar that juts out. That must be on the upper side of the creek's mouth; because Paul said bars nearly always form there. How about that, Paul?"

"Go up head, Phil; you've struck the bull's eye," replied the other, with a laugh, as he began to head in toward the crooked tree mentioned, and which doubtless he took for his landmark when in search of the creek.

The Comfort was in the lead now. Jack was content to play "second fiddle," as he called it. As Paul had gone through the disused canal in his canoe, exploring it pretty thoroughly, he must act as pilot.

Once they had pushed past the mouth of the creek they found a rather disheartening prospect. The water seemed very low, so that they could see bottom everywhere. Even Paul frowned, and shook his head.

"It surely must have lowered several inches since I was here yesterday," he declared, in dismay.

"Think we'll get through safely?" queried Jud Elderkin, anxiously.

"I hope we may," replied the scout master; "but we've just got to creep along, and be mighty careful. You see, most of the bed of this canal is mud, and not sand. Once the sharp bow starts to rooting in that, there's no telling how far we'll explore before letting up. And it's surprising how that same mud clings. I could hardly work my light canoe loose two or three times. Just seemed like ten pair of hands had hold of her, and were gripping tight. Easy there, Jack, take another notch in your speed, old fellow! Crawl along, if you can. And have the poles ready to fend off, if we get into any bad hole."

The boys were strung along the sides of the slowly moving motorboats.
Every fellow came near holding his breath with nervousness.

"Excuse me from getting stuck here in this nasty mess," remarked Nat
Smith, on board the roomier boat with Jack, Bobolink, Tom Betts, Andy
Flinn, Curly Baxter, Spider Sexton, Frank Savage and Bob Tice.

"Why, we might stay here a week," observed the last mentioned, in a voice that told plainly how little he would relish such a mishap, when they had planned such splendid times ahead.
