ACROSS THE OCEAN; OR, A BOY'S FIRST VOYAGE.

A True Story.

BY J. O. DAVIDSON.

Chapter VI.

AN OCEAN PRAIRIE.

Frank found his new work tolerably easy, though it required constant attention, for every joint of the machinery had to be watched, and oiled afresh the moment it began to get dry and hot. There being two other oilers, he now stood his regular watch of three hours at a time, having the rest of the day to himself. Most of this leisure time was spent in talking with Herrick, or studying the ins and outs of the machinery; and Frank soon learned to "take a card" as well as any man on board. This is done as follows: a slip of paper is rolled round a brass tube attached to the valve of the engine cylinder, and a pencil fixed so as to trace certain curved lines on the paper as it turns, the shape of which shows the exact working condition of the engine.

On the fourth afternoon of his new duties Austin heard himself hailed from the upper deck by a familiar voice:

"Hello, Frank, my boy! come up and have a look at Daddy Neptune's pasture-ground."

Up went Frank with all speed; but his first glance around made him start. Instead of the deep blue water that had surrounded her a few hours before, the ship was now in the midst of a smooth green plain, extending as far as the eye could reach, and covered, to all appearance, with coarse grass and broad-leaved plants. Nothing was wanting, in fact, to complete the picture except a few sheep and cattle.
