He heard the signal from the excited captain of the Spanish boat for more speed, and the throbbing of the machinery told that they were endeavoring in the engine rooms to carry out the order. It seemed as if the engines were already doing their utmost, but Clif could notice a slight increase in the headway they were making.

It was a fast boat and no mistake, Clif thought, as he anxiously strained his eyes to see what the Wilmington was doing.

Answering signals told that she had received the order from the flagship, and that those orders would be obeyed. Clif fervently hoped that she would be successful. He hated to think of the possibility of a hostile ship succeeding in running the blockade, and now this patriotic impulse was heightened by the fact that he was a helpless prisoner on board the very boat that promised to accomplish that feat.

For, as he watched the race, there was a growing conviction in Clif's mind that the Wilmington was so far out to sea that she could not hope to stop the Spanish steamer except by the power of her guns. And a hole in the side of the enemy's vessel, however desirable under ordinary circumstances, did not coincide with his hopes or ideas on this occasion. He had no desire to share a watery grave with his captors.

The two boats were heading for the same point, the Wilmington seeking to block the path the other was following. One of her guns spoke out, but the shot fell short. She was not in range.

Faster went the Spanish boat, and nearer to the objective point raced the two vessels.

Clif breathlessly watched the pursuing craft whose success meant so much to him. Could she win?

The Spaniards shared his excitement, and watched their opponent with fully as much eagerness. At last they broke out into a cheer.

Clif was not slow to understand its import. The Spanish boat was making really a phenomenal run, and had reached a point where it was evident that if they maintained their speed they would soon be past the dangerous line. That once reached they could show the Yankee boat a clean pair of heels.

Clif's spirits fell when he realized that the Spaniards had good cause for their jubilation. There was no doubt now that the steamer could pass the danger line and then away.
