"And you are some boy, Roger."
"I? Why Charley, I'm just beginning to realize that I have gone through life with my eyes shut. The man with one idea misses most of life. I went up there with the intention of threatening a lot of savages. I've come away feeling as if I'd met a group of intelligent and kind hearted fellow humans."
"It was wonderful of them, wasn't it!" exclaimed Charley. "I had no idea they felt under obligations, to me. I certainly didn't want them to."
Roger nodded and looked at his watch. "It's only nine o'clock now. If it wasn't so frightfully hot and there were any place to go, I'd say let's continue our spree."
"Just beyond that strip of desert there," Charley pointed into the valley to the east, "there are some wonderful Indian inscriptions on some rocks around a spring. I've never seen them, but I've always wanted to and I know the trail. Dick has shown it to me."
"Let's try it," said Roger. "Peter, come on, you're getting fat and lazy. I believe it's about ten degrees hotter than usual."
It was an hour's climb down into the valley. It lost its level look on near inspection. In every direction a fine, powderlike sand lay in long undulating ridges. Neither rock nor cactus was to be seen. A faint wind was stirring and tiny eddies of sand rose against the sky.
"You see that peak, due east?" asked Charley. "Well, the spring is just at the foot of that in a little canyon. There's never any trail here at all, the sand drifts so."
"I'm glad we're heading for a spring," exclaimed Roger. "I know I can empty the gallon canteen by myself."
They started ahead, Roger leading, Peter following behind Charley. It was heavy slow walking. After perhaps an hour of it, during which conversation languished more and more, Charley said, "I don't feel as eager minded as I did about Indian writings, do you?"
"Well," replied Roger, stopping to wipe the sand from his face and to grin at Charley. "I wasn't eager about the hieroglyphics to begin with. I haven't taken a girl for a walk for years and I thought this was my chance!"
"How is your enthusiasm for that standing up?" chuckled Charley.
Roger cleared his throat. "You see, it's like this--" he began, his eyes twinkling.
Charley interrupted by catching his arm. "Look, Roger! There's a sand storm coming!"
Roger looked up the desert to the north. The familiar gray veil of sand was plainly visible. "Lord!" he exclaimed. "We'd better start back at once."
