"Must we go now, Papa?" Lulu asked in a coaxing tone which seemed to add, "I hope you will let us stay at least a little longer."

"Yes," he said; "my little girls may say good-night now and go at once."

They obeyed promptly and cheerfully, and before long the others followed their example, till Mr. Keith and the Captain had the deck to themselves.

They lingered there for quite a long while, seeming to have fallen upon some very interesting topic of conversation; but it was suddenly broken in upon by the sound of the flag-ship's drum, instantly followed by those of all the other vessels of the squadron.

"Ah, what is the meaning of that, Raymond?" asked Keith, gazing toward the war-ships with keen interest and excitement. "It sounds to me like a call to battle."

"So it is," replied the Captain,—"a night exercise at the great guns, training the men so that they may be ready for all the surprises of a time of war."

Even as he spoke his passengers came hurrying from the cabin, the ladies and young girls wrapped in dressing-gowns and shawls, hastily thrown on to conceal their night-dresses, one and another asking excitedly what was going to be done now. But even as the words left their lips the thunder of cannon burst upon their ears, drowning the Captain's voice when he would have replied.

"Oh, is it war, brother Levis, really war?" queried little Walter, in great excitement.

"No, my boy; only a playing at war, I am thankful to be able to say. You may look and listen without fear that any one is to be killed, or even wounded, unless through carelessness."

But the cannon were thundering again, ship after ship firing off whole broadsides at some imaginary foe. At length, however, it was all over, and the passengers of the "Dolphin" returned to their berths to stay there for the remainder of the night.
