"Don't you think of trying it," called Nick, from the Wireless, which was being held in leash by the now cautious skipper. "Why, this racking fever of anxiety would just kill us if it had to keep up much longer, and that's right, fellows, even if George here won't acknowledge the corn."

"Oh! shucks! it isn't half as bad as you make out, Nick. The trouble is, you're so plagued logy you can't keep the balance of the boat. These thoroughbreds are delicately constructed, you see, and have to be treated different from other boats."

"I should just guess, yes," complained poor Nick, in a dolorous tone. "A feller has to be thinking of the blessed old boat all the while, and forget his own aches and pains. Why, every muscle in my whole body is sore from the strain."

"I say, Jack, would ye moind turnin' the glass back yander and tellin' us what sort of thing that cloud is that hugs the wather so close? I've been watching the same some time now, and I do think it's comin' this way," Jimmy remarked, loud enough for the others to hear, so that immediately every eye was quickly turned in the quarter toward which the Irish lad had pointed.

Jack immediately felt a sudden thrill of alarm pass over him, even before he had focussed the glasses upon Jimmy's so-called "cloud." He suspected what it might prove to be, and the very thought of being caught out on the ocean by a fog gave him a decidedly unpleasant sensation.

"Say, that ain't a cloud, I bet you," declared Nick.

"Looks more like fog to me," Josh called out, "and as sure as you live, boys, it's creeping down this way and widening out like fun. Hey! Jack, ain't that fog?"

"It sure is," replied the one who held the glasses, as he lowered them and cast an anxious look in the direction of the shore, as though he would take a last survey before the land became blotted out.

This was one of the things Jack had feared. A sudden storm of course would have brought alarm in its train; but this silent yet gripping fog might be just as potent a force toward their undoing. Once it enveloped them, they were apt to grope along for hours, possibly working more and more out to see. And when a wind dissipated the fog, perhaps they could not see land!

Jack immediately determined to risk minor dangers by turning in more toward the shore. If he could only listen for the beating of the rollers on the beach, it would be possible to tell when they came to the open bay by the sudden cessation of this sound.
