But we stopped only twice before we reached a sign marked in the ground: "Look out!" The trail faltered, and an arrow showed which way to go, and we came to the spot where the Scouts had peeped over into the draw and had seen the enemy. Here another arrow pointed back, and we understood exactly what had happened. We took the new direction. The three Scouts had left as plain a trail as they could by breaking branches and disturbing pebbles, and treading in single file. Jed Smith was awful tired, by this time, for the sun was hot and we hadn't halted to eat. But picking the trail we made the circuit around the upper end of the draw and climbed the opposite ridge. The trail was harder to read, here, among the grass and rocks. By the sun it was the middle of the afternoon, now, and we must have been on the trail five hours. We waited, and listened, and looked and smelled, feeling for danger. We must not run into any ambuscade. A little gulch, with timber, lay just ahead, and a haze of smoke floated over it. This spelled danger. It was not Scouts' smoke, because Scouts would not be having a fire, at this time of day, smoking so as to betray their position. When we made a smoke, we made it for a purpose. The place must be reconnoitered. We spread. I took the right, Kit Carson the left, and Jed Smith was put in the middle because he was the littlest. It would have been good if we could have left our blanket rolls, but we did not dare to. Of course, if we were chased, we might have to drop them and let them be captured. We crossed a cow-path, leading into the gulch. It held burro tracks, pointing down; and it seemed to me that if there was any ambuscade down there it would be along this trail. Naturally, the enemy would expect us to follow the trail. Maybe the other Scouts had followed it and had been surrounded. So we crossed the trail, and I signed to Carson and to Smith to move out across the gulch and around by the other side. We did. Cedars and spruces were scattered about, and gooseberry bushes and other brush were screen enough; we swung down along the opposite side, and the smoke grew stronger. But still we could not hear a sound. We closed in, peering and listening--and then suddenly I wasn't afraid, or at least, I didn't care. Through the stems of the trees was an open park, at the foot of the gulch, and if there was a camp nobody was at home, for the park was afire! "Come on!" I shouted. "Fire!" and down I rushed. So did Carson and Jed Smith. We were just in time. The flames had spread from an old camp-fire and had eaten along across the grass and pine needles and were among the brush, getting a good start. Already a dry stump was blazing; and in fifteen minutes more a tree somewhere would have caught. And then--whew! But we sailed into it, stamping and kicking and driving it back from the brush. "Wet your blanket, Jed," I ordered, "while we fight."
