The only place on the opposite bank where teams could emerge from the water was very narrow, and a team striking below it in the dark would almost certainly be lost. Thus the problem of a safe crossing at night became a difficult one. It would be unsafe to build fires or use lanterns, as these would surely draw the attention, and probably the bullets, of the Indians.

Finally the plan was adopted of stretching a rope across the river, from bank to bank, on the lower side of the ford, with a line of men stationed along its entire length, so that no team could get below it. These were charged, as they valued their lives, to keep their feet in constant motion, and on no account to let go of the rope.

First the ambulances were put across. Then the spare stock and saddle-animals were led over, and securely fastened. Six spare mules, harnessed and attached to a loose rope, were held in readiness, on the farther bank, to assist any team that might get stalled in the river. Then, one by one, the heavily laden wagons began to cross, with two men leading each team. There was little difficulty except at the channel, where the mules were apt to be frightened at the sudden plunge into deeper water.

A mule hates the dark almost as much as an Indian; he dislikes to work in water, and above all he dreads miry places or quicksands, for which his small, sharp hoofs are peculiarly unfitted. He is easily panic-stricken, and is then wholly unmanageable. A team of mules, finding themselves stalled in a stream, will become frantic with terror. They utter agonized cries, attempt to clamber on one another's back, and frequently drown themselves before they can be cut loose from the traces and allowed to escape.

In spite of all the difficulties to be overcome, the wagons were got safely over, until only one remained, and it had started on its perilous journey. Those members of the party who stood in the water holding the rope were becoming thoroughly chilled, as well as wearied by the treadmill exercise necessary to keep their feet from sinking in the quicksand. Thus, though they still stuck manfully to their posts, they were thankful enough that this was the last wagon, and noted the sound of its progress with eager interest. They were all volunteers, for nobody had been ordered to remain in the river, and this fact added to the strength of purpose with which they maintained their uncomfortable positions.

Among them were Glen Eddy and Binney Gibbs, who, when volunteers were called for to perform this duty, had rushed into the river among the first. Now they stood, side by side, near the middle of the stream, and close to the edge of the channel. They rejoiced to see the dim bulk of the last wagon looming out of the darkness, and to know that their weary task was nearly ended.

The mules of this team were unusually nervous, splashing more than any of the others had done, and snorting loudly. The rope had been cast loose from the bank the party had so recently quitted, and all those who had upheld it beyond Glen and Binney had passed by them on their way to the other side. They, too, would be relieved from duty as soon as the team crossed the channel.

But there seemed to be some difficulty about persuading the mules to cross it. As the leaders felt the water growing deeper and the sandy bank giving way beneath them, they sprang back in terror, and threw the whole team into confusion. The wagon came to a standstill, and everybody in the vicinity realized its danger. The driver, feeling that the need for silence and caution was past, began to shout at his mules, and the reports of his blacksnake whip rang out like pistol-shots.

In the excitement of the moment nobody noticed or paid any attention to a gleaming line of white froth that came creeping down the river, stretching from bank to bank like a newly formed snow-drift. Suddenly a rifle-shot rang out from the bank they had left, then another, and then a dozen at once. The Indians had discovered their flight, and were firing angrily in the direction of the sounds in the river. The teamster sprang from his saddle, and, cutting the traces of his mules, started them towards the shore, leaving the wagon to its fate.

"It's time we were off, too, old man," said Glen, as he started to follow the team.
