By daylight the camp was astir; but Glen was the first to roll out of his blankets, and he had been down to the creek for a plunge in its cool waters before breakfast-time. Then followed another hard day's work. The train of twenty heavy canvas-topped army-wagons, each drawn by six mules, the three four-mule ambulances, and the drove of spare animals furnished to the expedition by the government, arrived during the morning. These wagons had to be loaded with the vast quantity of provisions and various supplies brought thus far by rail. Then the tents already up had to be ditched, and still others erected for the use of the engineer-in-chief and other officers of the party who were now hourly expected to arrive.
