The engine began to roll and plunge fearfully now, and the driver, looking out, saw that the rain had been very heavy, and that the track was almost unsafe. But he dare not slow down because of his close meeting point with the east-bound express. Instead of being frightened at the capers of the rolling, plunging engine, the Dane seemed delighted, and leaned far out on the fireman's side, and shouted and laughed as the world went by. Although the track was clear and straight, the driver kept a constant lookout, for he had no air, and the way the train was rolling it would be difficult for the trainmen to get to the brakes, and when they did get to them they were apt to be out of repair. Occasionally they crossed deep, narrow gullies on wooden bridges that shook as the engine struck them. These waterless streams in the West are treacherous. It is not enough to say that they are dry one hour and bank-full the next; for they will often fill to overflowing in a single minute. The water at times will roll down in a solid wall ten or twelve feet high.
