“Two months ago I was heading up from the Colorado river toward Chuckwalla Tanks. Passing the mouth of a box canyon I observed the footprints of a man in some old rotten lava formation. I could tell that the man who made those footprints was dying of thirst when he made them. He was traveling in circles, every twenty yards, and they always do that toward the finish. “Well, I hustled up that box canyon with my canteen, hoping I'd arrive in time. Judge of my surprise when I found this heap of bones. I investigated and discovered that owing to the peculiar formation in the box canyon the footprints were practically imperishable. A detailed explanation of the reason why they loom up so white would be interesting, but technical--so let it pass. Suffice the fact that Oliver Corblay made the same discovery when he drifted into that box canyon twenty years ago, and it gave him an idea. He had a message to leave to posterity and he left it in his empty canteen. However, unless attention could be called to the canteen, the man who found the skeleton would merely bury it and never think of looking in the canteen. So Oliver Corblay wrote that message in the lava; really the most ingenious piece of inlaid work I have ever seen. “I was the first man to travel that way in twenty years. I read the message in the lava and I looked in the canteen. Here is a copy of the story I found there. The original is in a safe deposit box in San Francisco. It is a diary of a trip which you made with Oliver Corblay and his _mozo_ when you first came out to this country from--well, never mind the name. It seems to annoy you. This diary tells all about the discovery of the Baby Mine, your attack upon him with a stone and your flight with the gold--in fact, a condensed history of that trip right down to the very day he died in that box canyon. “I was so tremendously interested in that remarkable story, Carey, that as soon as I had refilled my water kegs at Chuckwalla Tanks, I headed south again for Ehrenburg. Here, after much inquiry, I learned from two of the oldest inhabitants that a tenderfoot with a train of four burros had arrived there twenty years ago. They remembered you quite well, because you were so new to the country and so frightened after your experience in the desert. You told a tale of a sandstorm and of having been separated from two Indians you had employed. It seems you lay over in Ehrenburg for a week and put in your time working up a lot of rich ore. You gave a deputy United States marshal five hundred dollars to act as your bodyguard that week, and when your bullion was ready you shipped it by express to the mint in San Francisco. In the express office at Ehrenburg I found a record of that shipment. You shipped it under the name 'T. C. Morgan,' a reversal of your real name.
