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.
