"Because if we find what we're going after that's the sort of formation we may have to buck against until we get that stuff to Walsh," he replied coolly. "Beautiful prospect, eh? I reckon you'll understand better if I tell you how it came about.

"The day you left, Lessard had me up on the carpet again. When he got through cross-questioning me, he considered a while, and finally said that under the circumstances he felt that losing my stripes would be punishment enough for the rank insubordination I'd been guilty of, and he would therefore revoke the thirty-day sentence. I pricked up my ears at that, I can tell you, because Lessard isn't built that way at all. When a man talks to any officer the way I did to him, he gets all that's coming, and then some for good measure. I began to see light pretty quick, though. He went on to say that he had spoken to Miss Rowan about her father, and had learned that without doubt those two old fellows were headed this way with between forty and fifty thousand dollars in gold-dust, that they'd washed on Peace River. Since I'd been on the spot when Rutter died, and knew the Writing-Stone country so well, he thought I would stand a better show of finding their cache than any one else he could send out. He wanted to recover that stuff for Miss Rowan, if it were possible. So he wrote that order to Goodell and started me out to join you—with a warning to keep our eyes open, for undoubtedly the men who killed Rutter and held you up would be watching for a chance at us if we found that gold."

"Very acute reasoning on his part, I'm sure," I interrupted. "We knew that without his telling. And if he thinks those fellows are hanging about waiting for a whack at that dust, why doesn't he get out with a bunch of his troopers and round them up?"

"That's what," Mac grinned. "But wait a minute. This was about three in the afternoon, and he ordered me to start at once so as to catch you fellows as soon as possible. I started a few minutes after three. You remember the paymaster's train left that morning. He had a mounted escort of six or seven besides his teamster. The MacLeod trail runs less than twenty miles north of here, you know. I followed it, knowing about where they'd camp for the night, thinking I'd make their outfit and get something to eat and a chance to sleep an hour or two; then I could come on here early in the morning. I got to the place where I had figured they would stop, about eleven o'clock, but they had made better time than usual and gone farther, so I quit the trail and struck across the hills, for I didn't want to ride too far out of my way. When I got on top of the first divide I ran onto a little spring and stopped to water my horse and let him pick a bit of grass; I'd been riding eight hours, and still had quite a jaunt to make. I must have been about three miles south of the trail then."

He stopped to light the cigarette he had rolled while he talked, and I kept still, wondering what would come next. MacRae wasn't the man to go into detail like that unless he had something important to bring out.

"I sat there about an hour, I reckon," he continued. "By that time it was darker than a stack of black cats, and fixing to storm. I thought I might as well be moving as sit there and get soaked to the hide. While I was tinkering with the cinch I thought I heard a couple of shots. Of course, I craned my neck to listen, and in a second a regular fusillade broke out—away off, you know; about like a stick of dry wood crackling in the stove when you're outside the cabin. I loped out of the hollow by the spring and looked down toward the trail. The red flashes were breaking out like a bunch of firecrackers, and with pretty much the same sound. It didn't last long—a minute or so, maybe. I listened for a while, but there was nothing to be seen and I heard no more shooting. Now, I knew the pay-wagon was somewhere on that road, and it struck me that the bunch that got Hans and Rowan and held us up might have tried the same game on it; and from the noise I judged it hadn't been a walkaway. It was a wild guess; but I thought I ought to go down and see, anyway. Single-handed, and in that dark you could almost feel, I knew I was able to sidestep the trouble, if it should be Indians or anything I didn't care to get mixed up in.

"I'd gone about a mile down the slope when the lightning began to tear the sky open. In five minutes the worst of it was right over me, and one flash came on top of the other so fast it was like a big eye winking through the clouds. One second the hills and coulées would show plain as day, and next you'd have to feel to find the ears of your horse. I pulled up, for I didn't care to go down there with all that lightning-play to make a shining mark of me, and while I sat there wondering how long it was going to last, a long, sizzling streak went zig-zagging up out of the north and another out of the east, and when they met overhead and the white glare spread over the clouds, it was like the sun breaking out over the whole country. It lit up every ridge and hollow for two or three seconds, and showed me four riders tearing up the slope at a high run. I don't think they saw me at all, for they passed me, in the dark that shut down after that flash of lightning, so close that I could hear the pat-a-pat of the hoofs. And when the next flash came they were out of sight.

"Right after that the rain hit me like a cloudburst. That was over quick, and by the time it had settled to a drizzle I was down in the paymaster's camp. Things were sure in an uproar there. Two men killed, two more crippled, and the paymaster raving like a maniac. I hadn't been far wide of the mark. The men that passed me on the ridge had held up the outfit—and looted fifty thousand dollars in cold cash."

"Fifty thousand—the devil!" I broke in. "And they got away with it?"

"With all the ease in the world," MacRae answered calmly. "They made a sneak on the camp in the dark, clubbed both sentries, and had their guns on the rest before they knew what was wrong. They got the money, and every horse in camp. The shooting I heard came off as they started away with the plunder. Some of the troopers grabbed up their guns and cut loose at random, and these hold-up people returned the compliment with deadly effect.
