nded in
a gurgle, as Sandy suddenly disappeared.

"Why, what can this mean?" asked the young captain. "Has he caught his
spurs into each other?"

"More than likely he got tangled up in one of those boat chains,"
remarked Life Knox. "I noticed the chains hanging around when the bridge
was put down."

"Then they'll take him to the bottom, sure," said Artie, and grew more
anxious than ever for his cousin's safety.

The disappearance of Sandy had been noticed from the bridge and from
both shores, and now several small boats put out. Titus Lyon broke away
from those who held him and went overboard with a loud splash, and two
minutes later a boat picked him up, more dead than alive.

When Artie and Life reached the spot where Sandy had disappeared,
nothing was to be seen of the young lieutenant, and a blank look seized
upon the faces of the would-be rescuers. Suddenly, however, the tall
Kentuckian gave a leap to the stern.

"There he is!" he shouted.

"Where?"

"Under water several feet. He is going down!"

As Life spoke he threw off his coat and hat, his boots followed,--in a
moment he slipped overboard.

The boat had now swung around with the current, and Artie had his hands
full bringing her up to the proper position and holding her there.
Artie's heart was in his throat. Poor Orly Lyon had been shot down in
battle, and now, if Sandy was also lost, what would his Uncle Titus and
his kind-hearted Aunt Susan do?

"Oh, I do hope Life brings him up!" he thought, when the head of the
Kentuckian appeared, dripping with water. Life supported Sandy in his
arms, and Artie brought the flatboat up close. In a moment Sandy was
laid on the seat and the captain of the seventh company clambered in.

The eyes of the lieutenant were closed, and Artie could not tell whether
he was dead or otherwise. "Is it--it all right?" he faltered.

"I hope so, Artie. He had his ankle caught in a chain just as I
supposed. It was hard work releasing him, I can tell you. Let us get to
shore just as fast as we can."

Artie needed no urging to do this, and soon the flatboat grounded on
the south bank of the river, and willing hands carried Sandy to a grassy
bank where he was rolled and worked over, until the water came out of
him, and he gave a gasp.

"He's all right now," said Life, drawing a long breath.

"Yes, and I'm mighty glad of it," murmured Artie.

Surgeon Farnwright then took charge of the case, but Sandy scarcely
needed him.
