The forward deck was comparatively dry; but the after part of the vessel was in a continual smother of spume and broken water. Now and then a wave would charge and break over her, drowning everything and everybody aft of the engines.

These waves seemed racing to overtake and smother the chaser. The tons of water discharged upon her decks would have sunk a less buoyant craft. All she did was to squatter under the weight of the water like a duck, her propellers never missing a stroke!

Whistler Morgan and his chums did not remain below through this run. No, indeed! The hardiest stomach would feel squeamish at such times in quarters like those of the crew of the S. P. 888.

At least the Navy boys got fresh air on deck if they were battered around a bit. They were supplied with slickers, and they had been wet many a time before.

Frenchy Donahue raised his shrill voice in the old dirge: "Aren't you glad you're a Navy man? Oh, mother!" and had not intoned the first lachrymose verse through to the end before Ikey Rosenmeyer interrupted with a shout:

"Look there! She's broke loose! Hey, fellers! don't you see it?"

They were hanging to a lubber line near the quarterdeck, which on the chaser was a part of the after deck having imaginary boundaries only, established by order of the chaser's commander.

The depth bomb lashed there was the object to which Ikey called his mates' attention. A line had snapped, and the heavy cylinder rolled slowly across the deck.

Suddenly the vessel heaved to starboard, and with a quick snap the bomb rolled in the other direction, crashing against the port rail in a way which made Whistler Morgan cry out in warning:

"Have a care, fellows! If the safety pin isn't firmly inserted in that bomb, and drops out, she may blow off."
