I was working with Himan, the civil engineer, when we built this incline. We built the bents on the ground, marked a centre, then hoisted them upright, and while Mexicans held it steady with guy-ropes, I climbed on top and gave Himan a “sight” with a pencil, while the men moved it on the mud-sill, with bars, one way or another as he directed. I did not relish the job, as I had a very poor head for working on heights, and had little faith in the men on the guy-ropes. Himan used to laugh at me, but one day we were up in the extractor house and he walked out on a 2-inch by 12-inch plank that was laid out to the first bent. A 2-inch plank over a 15-foot span bends considerably under a man. However, he got out all right on the bent, and, after looking at the placing of some sheave wheels, he started back. He had already begun to get giddy, and, when he stepped on the plank and it bent, he lost his nerve so much that in spite of my laughing at him he crawled in on his hands and knees. After the incline was completed, we put up a 4-inch by 12-inch plank “run-way” the whole length between the tracks for the men to go up and oil the sheaves. Working on heights is all a matter of practice, and few men can do it the first time, though of course there are exceptions. Once when shingling a very steep roof I worked the first two days sitting in a sling and expecting every few minutes to fall off; but after a while, with three or four pair of heavy woollen socks to keep me from slipping, I was running all over the same roof and never thought of falling. I have won many bets from cow-punchers who came to the mine that they could not run up the 900-foot incline in two minutes. They would start away at racing gait, then, as the incline left the ground, they would slow down to a walk, and finally they could be seen carefully placing one foot in front of the other, till generally they gave up and came back. As one fellow said, “Down here that plank is wide enough for me to ride my horse on, but up there it is like walking a tight-rope.”
