"That's the programme for the other boys, Doctor. You and I will in the meantime set up the chute through which we are to send the results of our chopping into the valley below. Fortunately there is a straight slide down the mountain, free from trees and landing at the right place. It was used some years ago to send big stones down. All we've got to do is to build a short chute at this end of it. Gravity will do the rest."

"But, I say Jack," broke in little Tom, "If we begin to chute sticks down there and anybody should be in the way—"

"But there'll be nobody in the way," answered Jack. "You don't imagine that I left so serious a matter as that to chance, do you? I've arranged the whole thing. Our slide ends in a spreading sort of flat down there in the valley that embraces an acre or so of level ground. Our timbers will go down there with the speed of cannon balls, but when they get there they'll slow up as the descent grows gentler, and stop on the level ground. Now I've arranged with the railroad people that we're not to send anything down the chute till to-morrow afternoon at the earliest, and that after that we are to send nothing down till three o'clock each day. That's to give them a chance to collect the stuff, haul it away and measure it."

"By the way," asked the Doctor, "how are we going to keep tab on their counts and measurements? Must we simply trust the contractor's men for all that?"

"Not by any means," answered Jack, who carried a very good business head on his shoulders. "Not by any means. We'll keep our own count up here. On every hundredth tie that we send down I am to mark 100, 200, 300 and so forth, according to the count, using a piece of red keel for the purpose. On every big bridge timber that we send down I am to mark the length and smallest diameter, keeping an account of it all up here. As for cordwood, every time we have sent down ten cords I am to send down a slab indicating the amount. All these markings of mine will be verified below, of course, and when we go down in the spring the contractor or, rather, his agent with whom I made our bargain—for I didn't meet the contractor himself—will settle with us. He knows us only as a single source of supply, and will credit everything we send down to the whole party of us. So as between ourselves we must keep our own accounts so as to make a proper and equitable division of the proceeds of our work when the springtime comes. To that function I appoint Ed Parmly. He is to keep our books. He has had experience in that sort of work in his father's store, and we'll look to him to keep a record of every fellow's contribution to the supply of timber sent down."

"But Jack," broke in little Tom, "how are we to estimate the amount of cordwood we send down the chute?"

"We won't estimate it at all. We'll cord it up and measure it before we send it down, just as we'll count our ties and measure up our bridge timbers. What's that?"

All the boys had started to their feet at the sound of something that seemed to be a human being in excruciating agony.

After a long pause there was a repetition of the strange, pitiful cry.

"May I use your rifle, Doctor?" asked little Tom. "That's a fellow that I don't care to tackle with a shot gun, and I've located him pretty well."
