three o'clock
The herders cooked their own meals out on the range , and after this the boys would eat with them . But to-day they were invited guests in the home of the rancher and hanker . In the meantime Professor Zepplin and Mr. Simms had become interested in each other and already were looking forward to the next few days on the range together , with keen pleasure . The start was made shortly after three o'clock , the party reaching their destination well before sundown . The Pony Riders uttered a shout as they descried the white canvas top of the chuck wagon . It was a familiar sight to them . On beyond that was a perfect sea of white backs and bobbing heads , where the great herd was grazing contentedly after its long journey to the free grass of Montana .
