I could not see that any of our warriors were falling; they were keeping themselves pretty well protected with their shields. Capping the slope where all this was going on was a long, narrow wall of rock running out from the summit of the range, and happening to glance up at it I saw numbers of the enemy hurrying out along it to get opposite our men and shoot down at them. I instantly urged my horse forward, shouting as loud as I could, but no one looked back and I knew that I was not heard. I went on to where the horses had been left, jumped from mine there and ran on out along the slope, shouting again and pointing up to the top of the rock wall. At last some one saw me, and gave the alarm, and the whole party stopped and looked at me, then up where I was pointing and saw their danger, and all turned and started to retreat.

But they had no more than started than the enemy began firing down at them. It was a long way down, several hundred yards, and their arrows and the few balls they fired did no damage; and seeing that, one of the enemy toppled a boulder off the cliff. It struck the slope with a loud crash and rolled and bounded on almost as swiftly as a ball from a gun, and I expected it to hurl three or four of our running men off the trail and down over the edge of the cliff. But when within twenty or thirty feet of the line it bounded high from the slope and shot out away over the trail, and away out over the cliff, and long afterward I heard it crash onto the bottom of the chasm.

Now the enemy abandoned their weapons and began, all of them, to hurl boulders down onto the slope. Had they done that at first they would likely have swept many of our men off the trail and over the cliff; but now the most of them had passed the danger line. As the last of them were running out from under the outer point of the wall, a man there loosed a last big rock; it broke into many pieces when it hit the slope, and these went hurtling down with tremendous speed. There was no possibility of dodging them; two men were struck; one of them rolled down to the cliff and off it, but the other, the very last in the line, was whirled around, and as he dropped, half on and half off the trail, the man next to him turned back and helped him to his feet, and without further assistance he staggered on to safety. He was Lone Walker. His right shoulder was broken and terribly bruised. The man we had lost was Short Arrow, young, just recently made a warrior.

We all gathered where the horses had been left, and a doctor man bound the chief's wound as best he could. There was much talk of Short Arrow's sudden going, and regret for it; and there was rejoicing, too; the enemy had paid dearly, seven lives, for what buffalo and other game they had killed out on the Blackfeet plains.

The sun was setting. As we tightened saddle cinches and prepared to go, we had a last look out along the slope. A great crowd of people was gathered on the summit watching us, and up on the wall top over the trail, sharply outlined against the sunset sky, dozens of warriors were gathering piles of rocks to hurl down at us should we again attempt to cross the slope. Our chiefs had no thought of it. The enemy had been sufficiently punished, and anyhow the stand that they had taken was unassailable. We got onto our horses and hurried to get down into the valley below the rock wall while there was still a little light, and from there on let the horses take us home.

We arrived in camp long after midnight. The people were still up, awaiting our return, and the greeting that we got surprised me. The women and old men gathered around us, shouting the names of the warriors, praising them for their bravery, and giving thanks to the gods for their safe return. But there was mourning too; when the noise of the greeting subsided we could hear the relatives of Short Arrow wailing over their loss.

I did not sleep much that night; every time I fell into a doze I saw the bodies of the enemy bounding down that rocky slope and off the edge of the thousand foot wall, and awoke with a start.

Although suffering great pain in his shoulder, Lone Walker the next morning declared that he was able to travel, and camp was soon broken. After crossing the valley of Cutbank River we left the big south trail, turning off from it to the southeast, and after a time striking the valley of another stream, the Nat-ok-i-o-kan, or Two-Medicine-Lodge River. I learned that this was the main fork of Kyai-is-i-sak-ta, or Bear River, the stream which Lewis and Clark had named Maria's River, after the sweetheart of one of them. But I did not know that for many a year after I first saw it.

We went into camp in a heavily timbered bottom walled on the north side by a long, high cliff, at the foot of which was a great corral in the shape of a half circle, the cliff itself forming the back part of it. It was built of fallen trees, driftwood from the river, and boulders, and was very high and strong. Red Crow told me that it was a buffalo trap; that whole herds of buffaloes were driven off the cliff into it. I could not understand much of what he told me, but later on saw a great herd decoyed to a cliff and stampeded over it, a waterfall of huge, brown, whirling animals. It was a wonderful spectacle. I shall have something to say about that later on.
