As was mentioned, the two brothers had their hammocks slung near that of Hank Dell. Nine o’clock is the hour when all blue-jackets must be in their hammocks, unless allowed to stay up for some entertainment, of which there are many aboard the ships.

At 7:30 A.M. on the first day out, when Frank and Ned went to sling their beds, in readiness for the night, Frank saw Hank near Ned’s lashed hammock.

“Guess you’re making a mistake, aren’t you?” said Frank. “That isn’t yours.”

“Oh, that’s so!” exclaimed Hank, with affected surprise. “I’m a bit green about things here. Mine’s over on this side,” and he went to his own sleeping quarters.

Frank thought no more about it at the time, but slung his own hammock. Ned, coming down a few minutes afterward, did the same. Then, as the time was free up to nine o’clock, the brothers went on deck to enjoy the air, for the day had been hot.

“Say, it’s simply great, isn’t it?” remarked Ned, as he gazed off over the heaving waters, silvered by the moon.

“Couldn’t be better,” declared Frank. “It’s the best life ever!”

The signal came for turning in, and the men, rather regretfully perhaps, went below.

As Ned sprang up into his hammock it gave way with him, and down he came with a crash, turning over so that he fell on deck, off the mattress, bruising himself painfully.

“Hurt?” asked Frank, hurrying to his brother’s side.
