He caught sight of Rayburn, who was stifling a yawn.

"You did jolly well, Phil!" he exclaimed. "We would have been in a pretty kettle of fish if you hadn't been here. But you're tired. How about turning in?"

"I'm not tired, really," protested the Tenderfoot. "I'll take a turn at the pump if you like."

"Right-o," agreed Dick. "We may have to have spells at it all night; but I think I'll try to find out where it's coming in and have a go at stopping it."

Switching on his electric torch, Roche squeezed through the small doorway between the engine-room and the forepeak. He could hear an ominous trickle coming from the neighbourhood of the chain-locker.

Investigations resulted in the discovery that the Olivette's bows had been badly damaged in spite of the partial protection afforded by the "pudding" fender. Several planks had been started on either side of the stem, and although most of the damage was above water-line, there was a considerable leak where a seam or two had burst.

Procuring some grease and cotton-waste, Dick proceeded to caulk the faulty seams, but his efforts in that direction were rewarded with poor success. It was impracticable to use any degree of force, because the fastenings of the planks were in such a weak state that the planks themselves began to give; and without ramming the caulking well home, the cotton-waste would not remain in position.

"Better let well alone," decided Roche. "It's jolly tedious work manning the pump, but we'll keep the old hooker afloat."

Having reported the result of his investigations, Roche proposed that each of the three Sea Scouts should take fifteen-minute tricks at the pump.

"That will give each of us half-an-hour spells," he added. "One or both of the others can stop on deck to keep a look-out for the liberty men."
