"Well," Tommy said, rummaging the provision box, "if we start out to get a couple of grizzly bear rugs for a Boy Scout club room in Chicago, we probably won't get back before sunrise, so we may as well take a little something to eat with us."
"Trust you for always taking something to eat with you!" laughed Sandy. "It's a sure thing you'll never starve to death."
The boys provided themselves with plenty of sandwiches and a couple of cans of pork and beans and, after seeing that the fire was safe and not likely to spread to the tents and provisions, and after changing the feeding ground of the burros so that they had plenty of grass, started away toward the foothills.
"Of course," Tommy said as they walked along, "we may find Wagner while we are looking for bear, and Will and George may find bear while they're looking for Wagner. I've heard of such things before now."
The boys crossed the valley to the foothills and clambered up the slope not far north of the spot where their chums and Chester had gained the summit. They descended into the gulch, too, and turned to the left.
"Now," Tommy said, seating himself on the slope, "the moon ought to be up in half an hour. I've heard that at the time the moon comes up bears leave their beds in search of food. We'll just sit here on the slope and watch the line of foothills."
"And I suppose," Sandy scoffed, "that you've got a notion in your nut that a couple of grizzly bears will come walking out into the gulch, take off their hides, and make you a present of them in a nice little speech."
"Now don't get smart, Freshy!" exclaimed Tommy. "According to all accounts, the walls of many of these foothills are punctured with limestone caves. There's where the bears live. From where we sit we can see a long ways to the north, as soon as the moon rises and we may be able to catch sight of a grizzly coming out for an early lunch."
The lads were seated not very far from the entrance to the cavern which had been occupied by Wagner and his son, but they had no knowledge of the fact. It was not their purpose to investigate one cavern at a time, but to watch the valley for anything that might come out of any one of them.
They could see only a short distance when they halted but presently the moon lifted into the sky and diffused a faint light over the hills. It would be some minutes before the direct rays would, strike into the gulch, and so the boys waited, hiding in the shadows, for that time to come.
