"Good heavens," ejaculated Malcolm, "the man overboard can't swim a stroke!" Heedless of the fact that of all the party he was the only one who had not removed his boots, Malcolm ran aft. With a bound he cleared the rail and dived overboard.

Fortunately for him, the Awarua was moving at a comparatively low speed. As it was, in spite of the momentum of his leap, he struck the water obliquely, and with a thud that temporarily winded him.

Coming to the surface, he took in a deep breath of salt-laden air, rubbed the water from his eyes, and looked for the missing man.

On the crest of a roller he espied the rifleman's head and shoulders and outstretched arms. In the interval that had elapsed between the accident and Malcolm's dive the ship had travelled a good hundred yards. Midway between the would-be rescuer and the object of his attentions floated the life-buoy, its position clearly indicated by a cloud of calcium smoke. He could see no sign of the life-belt.

Using a powerful trudgeon stroke, Malcolm started and swam towards the spot where he had caught a momentary glimpse of the man. In less than two dozen strokes he found that his saturated sleeves hampered his arms. His boots, too, were acting as a drag, yet there was no time to tread water and kick them off.

On the crest of the third roller Malcolm again caught sight of the man. He had ceased to struggle and was floating without any apparent motion, his head and shoulders clear of the water.

Changing to breast stroke, Carr slid down the slope of the long roller. Then, as he rose on the succeeding crest, he found that he was within ten yards of the man.

"Hang it all!" thought Malcolm as he approached. "I might have saved myself a job. He's better off than I am. The bounder's wearing a life-saving waistcoat."

"Hallo, Sergeant!" gurgled the rifleman. "Did that rotten boat sling you out too? When are they going to pick us up? The water's none too warm. I'm feeling nipped already."

"Oh, it's you, Macready!" exclaimed Malcolm, recognizing a Canterbury farmer, a fellow of magnificent physique. "When are they going to pick us up, you ask? Can't say. I rather fancy they'll have to reverse engines and stop before they lower a boat. That will take some time."
