I went ahead a little bit, close enough so I could see that shelter better. It had _me_ guessing. As near as I could make out there were branches laid all over the canvas--I mean on top. I didn’t know why any one would want to do that. The whole thing looked sort of like a thatch roof sticking out from the rocky wall, with canvas hanging down to the ground on the side where I was. It was a blamed crazy looking outfit, I’ll say that. Maybe it was meant to be camouflaged, that’s what I thought. I wasn’t going to go marching up to it, you bet. Even I took off my sneaks before I went back to Pee-wee so I could feel the twigs with my bare feet and wouldn’t make a sound by breaking them. All of a sudden I heard a kind of a rustling sound but I guess it was only a bird. “Come back a little,” I said to Pee-wee, “and be careful how you walk.” “I’ve got my shoes off already,” the kid whispered, “and I tied the laces together and I’ve got the shoes hung around my neck--that’s the way Scouts used to do. And if you keep your mouth shut then you’ll be sure to keep from sneezing.” I had to laugh. “Well, you keep your mouth shut,” I said. When we got a little further away from the place we stopped and I said, “That’s the darnedest, funniest thing _I_ ever saw. It looks like a pigpen with tent sides to it. The top is all covered with brush. That would never keep it from leaking. What do you suppose is the idea? Maybe it’s meant to be disguised--what do you say?” Pee-wee grabbed hold of me and pushed his mouth tight against my ear and whispered, “I bet you it’s those bandits that robbed the post office, I bet you it is! And I’m going to find out.” “You’re going to do nothing of the kind,” I said. “If it’s robbers, or even tramps, we better keep away. Come ahead back to our tent--we’ll find out to-morrow.” “Do you think I’m a quitter?” Pee-wee said. “Do you think I can’t sneak up there without making any sound? Didn’t I stalk a rabbit and he never knew it till another rabbit told him? You wait here and hold my shoes. Now we’ve got a dandy mystery--it’s a good mysterious one.” “All right,” I said, “but for the love of goodness be careful. When you come back, how can you tell where to find me in the dark? I tell you the way we’ll do. I’ll--shh----” “What is it?” he said. “I thought I heard a sound,” I told him. “This is the way I’ll do--shh--I’ll keep close in by the wall and you come along close to it, then you’ll be sure to find me. I know a place where we can scramble up if we have to and get out of the chasm. And look out you don’t make any sound. I don’t know who’s there, but the place has got _me_ guessing.”
