While Rollo and Jane were watching the sailors, they saw them unfurl one after another of the sails, and spread them to the wind; for the wind was now fair, and it was fresh enough to assist the engines considerably in propelling the ship through the water. Still, as the ship was going the same way with the wind, the breeze was scarcely felt upon the deck. The air was mild and balmy, and the surface of the sea was comparatively smooth, so that the voyage was beginning very prosperously. Rollo looked all around the horizon, but he could see no land in any direction. There was not even a ship in sight; nothing but one wide and boundless waste of waters.
"I should think that there would be some other ships going to England to-day," he said, "besides ours."
Jane did not know what to think on such a subject, and so she did not reply.
"Let us watch for whales," said Rollo. "Perhaps we shall see a whale. You watch the water all along on that side, and I will on this side; and if you see any whale spout, tell me."
So they both kept watch for some time, but neither of them saw any spouting. Jane gave one alarm, having seen some large, black-looking monsters rise to the surface not far from them on one side of the ship. She called out eagerly to Rollo to look. He did so, but he said that they were not whales; they were porpoises. He had seen porpoises often before, in bays and harbors.
Just then the bell near the helmsman's window struck again, though in a manner a little different from before; for after the two pairs of strokes which had been heard before there came a single stroke, making five in all, thus:—
Ding—ding! Ding—ding! Ding.
Immediately afterward the sound was repeated in the forward part of the ship, as it had been before.
Ding—ding! Ding—ding! Ding,
"I wonder what that means," said Rollo.
