"We will go on, Mr. Lang. Perhaps it is as well that we have been broken in properly at the start. We shall be in better form to cope with real emergencies if such arise," declared Grace.

"Real! Huh!" grunted Hi Lang.

"Oh, you'll get used to having things happen," soothed Hippy Wingate. "Wherever this outfit goes there is trouble and then some more."

"Yes, but this is the worst," complained Emma Dean.

"Alors! Let's go," urged Elfreda Briggs as she got up after having arranged a sling to support the cowboy's injured arm.

Their ponies were led up by the cowboys and the girls mounted for a fresh start, Grace and Elfreda considerably rumpled and both very tired after their lively experience. The cowboys, having loaded their injured companion on a pony, now gave the Overland girls a rousing farewell whoop and trotted slowly homeward.

Hi Lang had uttered no comment on what had occurred, but he was keeping up a constant thinking, now and then scowling observingly at his charges. Of Grace and Elfreda he had no doubts, for, in his estimation, they had graduated from the tenderfoot class. The others had yet to prove themselves.

The ride was hot and dusty, and, in order to make up for lost time, the party was riding fast, but the ponies, though already flecked with foam, appeared to be as fresh as at the start.

"What time do you think we will reach the mountains?" called Anne, who was suffering tortures from the heat and dust.

"Sundown," briefly answered the guide. "It will be worse than this after we reach the desert."
