I had seen them before, and I wished they had been farther off, for one of them seemed to be determined to run over the raft, in her efforts to cut off her rival. Our craft was in the middle of the channel, and one of the steamers passed on each side of us, and so close that we were nearly swamped in the surges produced by their wheels. I breathed easier when the boats had passed, for I knew how reckless they were under the excitement of a race. I could hear them creak and groan under the pressure, as they went by.

We watched them as they rushed forward on their course. They were just rounding into the Ohio, on their mad career, when we saw one of them suddenly fly in pieces, torn, rent, shivered, the atmosphere filled with fragments. Then came a terrific explosion, like the din of an earthquake, shaking the raft with its violence. The boiler of the steamer had exploded.

CHAPTER XIX.

AFTER THE EXPLOSION.

When the explosion occurred, the wind was nearly dead ahead, and we were floating with the current, which was the particular reason why we had come so near being run down by the contestants.

"What's the matter?" asked Flora, alarmed by the noise, but unable to explain the cause of it.

"One of those steamers has burst her boiler. Didn't you see the pieces fly?" I replied.

"But where are the people we saw laughing and talking as she went by?" continued she, with a shudder.

"A good many of them will never laugh and talk any more."

"Hookie!" shouted Sim, as soon as he comprehended the nature of the disaster. "That's wus'n fallin' in the river."
