Here he worked for several months, and gradually rose to the position of night shift-boss or gang foreman. But he began to realize that he was exhausting the learning opportunities of this particular place and kind of work, and so one night deep down in the mine, when for sudden lack of ore-cars or power or some other essential, work was held up for the last half hour of his shift, he went off into a warm corner, curled himself up in a nice clean wheelbarrow and slept away the last half hour of his pick and shovel experience. He had decided to get into association, some way, with the best mining engineer on the Coast. There was no question about who this was at that time. It was Louis Janin in San Francisco. So he appeared at Mr. Janin's office as a candidate for a job, any job so that it was a job under Louis Janin. But the famous engineer, well disposed as he was toward giving intelligent, earnest young men who wanted to become mining engineers, a chance, had to explain that not only was there no vacant place in his staff but that a long waiting list would have to be gone through before Hoover's turn could come. He added, as a joke, that he needed an additional typist in his office, but of course----. The candidate for a job interrupted. "All right, I'll take it. I can't come for a few days, but I'll come next Tuesday, say." Janin was a little breathless at the rapidity with which things seemed to get settled by this boyish, very boyish, young man, but as they were apparently really settled he could only say, "All right." Now the reason that the new typewriter boy could not begin until next Tuesday--this was on a Friday--was that he had in the meantime to learn to write on a typewriter! Trivial matter, of course, in connection with becoming a mining engineer, but apparently necessary. So learning what make of machine he would have to use in the office, he stopped, on his way to his room, at a typewriter shop, rented a machine of proper make, and by Tuesday had learned to use it--after a fashion.
