Primitive as the device was, it answered.

The Bolo's head was drawn round toward the wind by this "drag," as sailors call it, and she no longer shipped cross seas. A few minutes later, Frank had two of the oil bags ordered by Ben ready. Once more the sailor crawled on to the plunging bow and made one of the devices fast on either side.

To Frank's amazement the seas at once began to subside—that is, in the immediate vicinity of the Bolo.

"That's what oil will do," commented Ben, gazing about him with a satisfied look. "It spreads a thin scum on the waves and prevents them breaking. Now we shall do nicely for awhile, though now the worst is about over, I don't mind admitting that I did think once or twice that we were bound for Davy Jones' locker."

After a lot of searching the cause of the engine's sudden stoppage was located. One of the bearings had become so heated in the struggle against the storm that the machine had ceased working. The cause was evidently that the violent "tumblefication" that the Bolo had gone through had hindered the proper operation of the force-feed lubrication. After giving the bearing time to cool off, Frank affixed a regular grease cup to it and no difficulty was then experienced in starting up the engine once more.

"No use in laying to," said Ben, after he had been consulted as to the advisability of going ahead. "The blow's as bad now as it will get, and we are being driven back every minute we aren't going forward. There's no such thing at sea as standing still."

The drag was accordingly hauled aboard, at no small risk; but the oil bags were left to drip their calming lubricant alongside. This done, the Bolo was put on her course again and slowly forced her way through and over the angry waves that seemed determined to prevent her progress. Owing to the heavy clouds that overhung the sky, ever and anon ripped open by a lightning flash, it grew dark at four o'clock, or eight bells, as Ben called it, and Bluewater Bill was sent forward with the lights. But they had hardly been placed in position when a huge sea swept the Bolo from stem to stern, extinguishing them instantly.

"No use putting out any more," said Ben, "we must trust to luck not to run across any vessels. I don't think that we are in the steamer track anyway."

But how wrong Ben's words were they all realized when, at about midnight, Harry, who had the wheel, thundered on the cabin top and yelled at the top of his voice:

"All hands on deck."
