Having breakfasted, Mr. Fogg and his companions resumed their places in the car, and observed the varied landscape which unfolded itself as they passed along the vast prairies, the mountains lining the horizon, and the creeks, with their frothy, foaming streams. Sometimes a great herd of buffaloes, massing together in the distance, seemed like a moveable dam. These innumerable multitudes of ruminating beasts often form an insurmountable obstacle to the passage of the trains; thousands of them have been seen passing over the track for hours together, in compact ranks. The locomotive is then forced to stop and wait till the road is once more clear.
