“Well, boy?” the captain turned impatiently on Jack.

“A message, sir. I think it’s important,” said the boy deferentially.

The captain glanced through it and whistled.

“Important! I should think it is. Just what I thought. Confound this ocean!”

He hastened over to his officers and showed them the despatch. A lively consultation followed, which Jack wished he could have overheard. He would have liked to know what further steps could be taken to avert the dangers amid which they were crawling forward.

As a matter of fact, all that could be done had been done. Humanly speaking, the Ajax was as safe as she could be rendered in the midst of the invisible dangers that, like white specters, might be swarming about her even now.

Jack was ordered back to the wireless room and told to stand by for any further information. The captain evidently placed great reliance on getting further word of the location of the ice-fields and bergs.

But, although Jack worked ceaselessly, sending out his crackling, sparkling calls, no reply came back out of the blinding fog. Clearly the ship that had sent the wireless that was so all-important had passed out of his zone, or else the “atmospherics” were arrayed against communication.

It was a thrilling and not altogether a comfortable thought to consider that at any moment there might loom above them, out of the choking mist, a mountainous white form that might well spell annihilation for the sturdy tanker.

Raynor, whose hand was now quite well, poked his head in at the door. He was grimy and soot-covered but cheerful, and was going off watch.
