“Look out!” roared Shaddy. “Heads down!” and Rob, who had been watching the obstacle in their way, only just had time to duck down as, with a tremendous rushing and crackling sound, they passed right through a mass of pendent boughs which threatened to sweep the boat clear of cabin and crew as well, as the stream urged it on.

The trouble only lasted a few seconds, though, and then they were through and floating swiftly round the inner curve toward an open patch of the shore which rose all clear of water and tree.

“Anybody hurt?” cried Brazier from inside the cabin; “I thought the place was going to be swept away after I had dived in here.”

“No, sir; we’re all right,” cried Rob. “I nearly lost my cap, though, and— Oh! where’s Joe?”

“Eh?” cried Shaddy, looking forward. “Why, he was— gone!”

All faced round to look back just in time to catch an indistinct glimpse of their companion apparently clinging to a bough overhanging the stream; but the next moment the intervening branches hid him from their sight, and a look of horror filled every face.

“Did—did you see him, Shaddy?” panted Rob.

“Thought I did, sir, but couldn’t be sure,” growled Shaddy, and then furiously to his men, “Row—row with all your might!”

The men obeyed, making their oars bend as they tugged away with such effect that they advanced a few yards. But that was all. The current was too sharp, and they lost ground again. Then, in spite of all their efforts, the most they could do was to hold their own for a minute before having to give way, pull in shore, and seize the overhanging boughs to which Shaddy and Brazier now clung to keep the boat from drifting.

“Better land, sir,” cried Shaddy. “We can’t reach him this way.”
