"Looks almost hopeless, doesn't it!" admitted Jerry, finally.
"Worst of it is we don't really know whether she's down below yet or if we've passed it. She was riding pretty low."
"Wonder what that man was doing on Lost Island?" speculated Jerry, crossing wearily to the north edge of the bridge and peering through the gray dawn-mist toward the island, barely visible now. A mere twinkle of light showed among the trees, and he stood there for a long minute. Dave come to his side, and the two waited in silence for the dawn. Jerry had almost fallen asleep standing up, when a sudden clutch at his arm nearly overbalanced him and sent him tumbling off the dizzy height.
"Look!" gasped Dave.
"What is it?" exclaimed Jerry, turning to his companion, all sleep gone.
"I'll swear it's the boat—right under us!"
CHAPTER IV
MORE THRILLS
It was only a bare few seconds before the floating object had passed within the shadow of the bridge, but there could be no doubt about it; it was a boat, riding so low that only her outline showed. Jerry rubbed his eyes in disbelief, but for only an instant. Then he sprang to the other side of the bridge, shedding hat, coat, trousers, shirt and shoes, on the way. So, at least, it seemed to Dave, who caught his chum's arm, as Jerry poised himself, his body white and gleaming in the moonlight, on the high rail that ran along the edge.
"What you going to do, Jerry? It's a good thirty feet to the water—and you don't know how deep it is down there."
