At this point an opening in the second growth of yellow pines permitted him a vista. He looked back. He had never been in this part of the country before. A little portion of Baldy, framed in a pine-clad cleft through the First Range, towered chill, rugged and marvellous in its granite and snow. For the first time Bob realized that even so immediately behind the scene of his summer's work were other higher, more wonderful countries. As he watched, the peak was lost in the blackness of one of those sudden storms that gather out of nothing about the great crests. The cloud spread like magic in all directions. The faint roll of thunder came down a wind, damp and cool, sucked from the high country. Bob rounded a bend in the road to overtake old California John, jingling placidly along on his beautiful sorrel. Though by no means friendly to any member of this branch of government service, Bob reined his animal. "Hullo," said he, overborne by an unexpected impulse. "Good day," responded the old man, with a friendly deepening of the kindly wrinkles about his blue eyes. "John," asked Bob, "were you ever in those big mountains there?" "Baldy?" said the Ranger. "Lord love you, yes. I have to cross Baldy 'most every time I go to the back country. There's two good passes through Baldy." "Back country!" repeated Bob. "Are there any higher mountains than those?" Old California John chuckled. "Listen, son," said he. "There's the First Range, and then Stone Creek, and then Baldy. And on the other side of Baldy there's the cañon of the Joncal which is three thousand foot down. And then there's the Burro Mountains, which is half again as high as Baldy, and all the Burro country to Little Jackass. That's a plateau covered with lodge-pole pine and meadows and creeks and little lakes. It's a big plateau, and when you're a-ridin' it, you shore seem like bein' in a wide, flat country. And then there's the Green Mountain country; and you drop off five or six thousand foot into the box cañon of the north fork; and then you climb out again to Red Mountain; and after that is the Pinnacles. The Pinnacles is the Fourth Rampart. After them is South Meadow, and the Boneyard. Then you get to the Main Crest. And that's only if you go plumb due east. North and south there's all sorts of big country. Why, Baldy's only a sort of taster." Bob's satisfaction with himself collapsed. This land so briefly shadowed forth was penetrable only in summer: that he well knew. And all summer Bob was held to the great tasks of the forest. He hadn't the time! Wherein did he differ from Hicks? In nothing save that his right of way happened to be a trifle wider. "Have you been to all these places?" asked Bob. "Many times," replied California John. "From Stanislaus to the San Bernardino desert I've ridden." "How big a country is that?" "It's about four hundred mile long, and about eighty mile wide as the crow flies--a lot bigger as a man must ride." "All big mountains?" "Surely."
