HOW THE LITTLE TRAP WORKED
"What do you think of it?" asked Frank, after they had stood there a short time, taking in the picture as seen in the late afternoon.
"It's hard to tell," Bob replied slowly. "It's so terribly big, that a fellow ought to take his time letting the thing soak in. That further wall looks as if you could throw a stone over to it; and yet they say it's more than a mile from here."
"Yes," Frank went on, "and all along in the Grand Canyon there are what seem to be little hills, every one of which is a mountain in itself. They only look small in comparison with the tremendous size of the biggest gap in the whole world."
"And how far does this thing run—is it fifty miles in length?" Bob asked.
"I understand that the river runs through this canyon over two hundred miles," the other replied. "And all the way there are scores, if not hundreds, of smaller canyons and 'washes,' reaching out like the fingers of a whopping big hand; or the feelers of a centipede."
"That's what I read about it away back; but I had forgotten," Bob remarked. "And they say that it would be a year's trip to try and follow the Grand Canyon all the way down from beginning to end, only on one side."
"I reckon it would, for you'd have to trace every one of these lateral gashes up to its source, so as to cross over. And that would mean thousands of miles to be covered."
"Gee!" exclaimed Bob, throwing up his hands as he spoke; "when you say that, it makes a fellow have some little idea of the size of this hole. And to think it's come just by the river eating away the soil!"
