Well might it be said that the good wishes and anxious thoughts of hundreds followed the gallant Hobson and the meager crew of the Merrimac as she steamed towards Santiago. High hope of success, apprehension increased by the darkness and uncertainty as to her whereabouts, kept everyone in a fever. No one could sleep, and from the open ports, and from the silent and darkened decks of battleships, cruisers, and gunboats, a thousand and more pairs of anxious eyes stared into the gloom.

"Where was she? Had she run aground? Had she lost her bearings in the darkness? Hush! Did anyone hear that? What was it then? Oh, only escaping steam? What a relief to think of it!"

The questions were passed along the decks, time and again, and for the most part left unanswered. Then, as each man became silent in despair of hearing anything, a faint, almost inaudible hail came across the heaving water.

"Hark! Huss-s-s-h! Did anyone hear that? What was it? Discovery?"

Almost instantly a spout of flame shot from a cliff beneath the Morro Castle, cutting the darkness in twain as with an arrow, while a deafening report set the air throbbing and reverberating. Another followed, and then a third, and within a few seconds a line of flaming dots cut along the dark hillside, while shells flashed brilliantly red in the air as they shivered into a thousand pieces. Nor was this all. The torpedo-boat Pluton was patrolling the entrance, and at once added the sharp, angry snap of her quick-firers to the din, while guns from another battery ashore, and from the Reina Mercedes, a battleship anchored within the harbor, played upon the black hull of the devoted Merrimac. Add to this a couple of torpedoes, which were discharged in her direction, and some idea can be obtained of the terrors that assailed her.

Meanwhile Hal had been by no means idle. No sooner had the moorings been dropped, than he opened the cabin door and went into the saloon.

"I'll just stay here till I think we're getting close inshore," he murmured; "then I'll get on deck. Let me think. The small torpedoes are placed to port; that means that I must get away to starboard to escape the explosion. Hobson stays on board for that, and so shall I. When she begins to sink, I shall go overboard, and swim straight for the shore. By Jove! I forgot a life-belt, but perhaps there's one in the cabin."

He ran back, and felt above his head for the racks upon which the belts are usually placed. A low cry of pleasure escaped his lips, for the very thing he wanted was there. Taking it down, he promptly slipped his arms through the slings and quickly buckled the belt on. Then he crept to the companion-way, and sat down upon the bottom step of the ladder, where he waited for what, in his overstrung condition, seemed to be hours.

Bang! The report made him start to his feet, and stand there holding to the rail, while the thump of his heart seemed to shake him from head to foot.

Bang, bang, bang! Crash! The Merrimac shivered as a six-inch shell struck her true in the center, and piercing her thin plates as if they were sheets of tissue paper, exploded forward of the engines, blowing a big gaping hole through the saloon in which Hal sat.
