The movement was made none too soon. The snow was already filling the air, and one morning, on coming from his tent, Theodore Roosevelt found the ground covered to a depth of a foot and a half. To add to his discomfort the pony he was riding began to buck that day and managed to dislocate his rider's thumb. But Theodore Roosevelt stuck to him and showed him who was master; and after that matters went better. The snow continued to come down, and before the end of the journey was reached, at Great Geyser Basin, the hunters almost perished from the cold.
