Fortunately for those interested in the adventures of the Motor Rangers, at that instant a freak of the current spun Joe’s body about and flung him, like a bit of driftwood, toward the side of the Nomad. In a flash Nat’s strong arm was about him. It was just in time, too, for Joe, who had been swept from the bridge unseen when the Nomad encountered the angry maze of cross currents and tide rips, was almost exhausted.

In this condition he was not in full possession of his ordinary presence of mind. He clung to Nat desperately, with a grip that threatened to pull both rescuer and rescued under water together.

Nat, battling with the sharp, angry waves, as choppy and angular as giant fangs, had all he could do without struggling with Joe. Again and again he tried to break the other’s grip, but without avail. The hold of a drowning man or boy is the most tenacious known. It is almost impossible to loosen it.

“Joe, you must let go of me!” gasped out Nat.

But Joe only clung in a more leech-like fashion. What with the other lad’s dead weight clinging to him, and the conditions against which he was laboring, Nat, strong as he was, felt his strength being rapidly sapped.

Luckily, so intense had been the heat, the lads wore only light tropical trousers and sleeveless undershirts. Had they been incumbered with ordinary clothes, they could not have survived a quarter of the time that Nat and Joe did.

Nat began hauling in on his line, but with Joe gripping him so tightly, it was too much of a task.

“Joe, I hate to do it,” he said at length, “but I must, old fellow, I must!”

With these words, Nat did what he would have done with anybody else when first he realized the conditions. He struck Joe a blow on the head that completely robbed him of his senses. The lad’s vise-like grip relaxed. Under these circumstances, Nat could handle him easily.

By strong, rapid, over-hand motions, he hauled himself and his burden closer and closer to the side of the Nomad. At last they reached it. And now came the most difficult part of Nat’s enterprise. He had to get back on board, and, more than that, to get Joe there, too.
