"It makes no particular difference," Mr. Emery replied in answer to Neal's question. "We can easily arrange the details later. Go into the engine-room and tell Jake to drive her at full speed, and to report if the water we are pumping in is likely to rise as high as the furnaces."

Promising himself that he would re-stow the goods on the gig, putting his father's with those belonging to himself and Teddy, as soon as this message had been delivered, he descended the companion-way after glancing rapidly around the horizon.

There was no land to be seen on either hand, and he understood at once why the order to keep the yacht going at full speed had been given.

The small boats were by no means stanch enough to be depended on for a long cruise unless the present dead calm should continue until they could reach land, and every effort was to be made to gain some of the islands in the vicinity.

When Neal entered the engine-room he believed for an instant that Jake had not heard of the terrible danger which threatened. Work there was going on as usual, except, perhaps, that the engineer and his assistants were watching the machinery a trifle more carefully than seemed really necessary; but when he repeated the message Jake's face grew just a shade paler.

"Say to your father that we have got on every pound of steam that can be raised, and it will be necessary to slow down presently because the bearings are growing warm. The water is already above the fire-room floors, and if the pump is worked an hour longer the fires will be drowned."

"But you must keep her going, Jake. It would be terrible to take to the boats when there was no land in sight."

"I'm bound to do my best; but a man can go only so far. Do you know where we are?"

"No."

"What is being done on deck?"
