"There's going to be a fight to-morrow," said the marine officer to Hal. "We've just had orders to march out and attack this Spanish encampment. Cubans will lead the way, so that we shall not be wantin' you as guide; but if you'd care to come, why, you know you're welcome."

"Just what I'd like. When do you start?"

"Early dawn. We'll get breakfast for all hands, and then away, so as to make a day's job of it. The ships are now going to throw shells into the bush."

He had scarcely finished speaking, when loud booming was heard from the sea, and missiles commenced to hurtle overhead. Every corner of the bush was searched by the exploding shells, but, in spite of the flying fragments, the same desultory and harassing fire continued, for the Spanish guerrillas clung tenaciously to their posts.

Next morning a force of six hundred, including marines and Cubans, marched from their bivouacs, Hal joining the party, armed as before with a rifle.

"I reckon we'll have to be precious wide awake," said his new friend. "Cubans are out as scouts, but in this thick bush we want something in the shape of a balloon. How far should you say we are from the Dons?"

"They told us that the camp was four miles from us," answered Hal. "We have been marching for an hour, so I fancy that we must be within half a mile or less of the enemy. Hillo! Lie down quickly!"

The silence of the bush, through which the troops were forcing a way, was suddenly broken by the crackle of musketry coming from directly in front. Fortunately, the marines were moving in open order, or otherwise the losses would have been heavy. As it was, no one was hit, though showers of leaves were stripped from the trees, and came tumbling in a cloud to the ground, or upon the heads of those who happened to be beneath.

"A Spanish ambush!" exclaimed the officer. "Here, sir, hop along over to the signaler, and tell him to let the Dolphin know whereabouts they are lying."

"Right! I'll do it!" cried Hal. "You can expect me back shortly."
