"Boys, we're in a petrified forest!" he exclaimed.
The boys would have been glad to explore the petrified forest that night had it been practicable. They had read of the mysterious stone relics of ancient woods, which exist in the remote Sierras, but they had never dreamed they would stumble upon one so opportunely. However, even had they been less tired, it would have been out of the question to examine the strange place more thoroughly that night.
As there did not seem to be any limit to the place so far as they could see, the boys decided to camp where they were for the night. The auto was stopped and the horse unhitched and turned loose at the end of a lariat to graze, his rope being made fast round one of the more slender stone trunks.
"Feels like hitching him to the pillar of the City Hall at home," laughed Joe, as he formed a double half hitch and left the horse to his own devices, first, however, having watered the animal at a small spring which flowed from the foot of a large rock at one side of the mysterious stone valley.
In the meantime, Cal had built a fire of sage brush roots, for there was no wood about, every bit of it having turned to stone long ages before. The pile, on being ignited, blazed up cheerfully, illuminating the sterile, lonely spot with a merry red blaze. The spider was taken out of the utensil locker, and soon bacon was hissing in it and canned tomatoes and corn bubbling in adjacent saucepans. A big pot of coffee also sent up a savory aroma. Altogether, with canned fruit for dessert, the Motor Rangers and their friends made a meal which quite atoned for the loss of their lunch. Even Ding-dong admitted that he was satisfied by the time Cal drew out a short and exceedingly black pipe. The former stage driver rammed this full of tobacco and then leisurely proceeded to light it. After a few puffs he looked up at the group around him. They were lolling about on waterproof blankets spread out on the rock-strewn ground, a portion of which they had cleared. In the background stood the dark outlines of the auto, and beyond, the mysterious shadows of the petrified forest, the bequest to the present of the long departed stone age.
"I've bin a thinkin'," began Cal, as if he were delivering his mind of something he had been inwardly cogitating for some time, "I've bin a thinkin' that while we are in this part of the country we ought to keep a good look out at night."
