He waited until he found himself on the crest of a long roller, and then looked in the direction of the Awarua. The transport was now nearly two miles away. Whether she had slowed down or was still steaming ahead he could not determine. As far as he could see there were no signs of a boat being lowered.

Macready was certainly right about the low temperature of the sea. Already Carr felt the numbing effect of the water. His fingers as he fumbled with the laces of his boots were practically devoid of feeling.

"I have one of those air waistcoats," explained the man. "It's only partly filled. Much as I could manage to do, that. I guess there's a tidy drop of water got in while I was blowing. If we can get more wind into the thing it'll support two; at least I hope so. The fellow at the stores said it would."

"Don't trouble on my account," said Malcolm. "I'll swim to the life-buoy and bring it back."

The patent life-saving device was still emitting dense clouds of calcium smoke. Provided the expected rescuing-boat made for that there was a good chance of Malcolm and the rifleman being picked up, unless in the meanwhile they were overcome by the acute coldness of the water.

"Any signs of a boat, Sergeant?" asked the man, as Malcolm, evidently exhausted by his exertions, pushed the life-buoy before him to within arm's length of his companion in peril.

Malcolm was reluctantly obliged to admit that the probability of rescue from that direction was of a diminishing nature. The Awarua was still holding on her course.

"Suppose they think that as we were a pair of fools to be slung overboard we aren't worth picking up," continued Macready.

Malcolm did not reply. He did not attempt to enlighten the man as to the reason why there were two "in the ditch" instead of one. He was also at a loss to explain the apparent callousness of the responsible officer of Transport 99 in not promptly lowering a boat and effecting a speedy rescue.

The two men were too intent upon the disappearing Awarua to notice the approach of the escorting cruiser. The latter was circling round the transport, and was on the point of turning at a distance of a mile astern, when the alert officer of the watch noticed the accident to the boat.
