Before him there unrolled a bright future. He was ambitious; he did not intend always to remain a mechanic. One day when he had learned all there was to know about the making of steam engines, he intended to drive one himself. He would be a locomotive engineer, nothing less. Meantime there were practical questions of food and shelter to consider immediately and he was not the boy to waste time in speculations for the future when there was anything to be done. He counted his money. Almost four dollars, and a prospect of two and a half every week. Then he set out to find a boarding house. Two dollars and a half a week, not a large living income, even in 1878. Henry walked a long time looking for a landlady who would consent to board a healthy sixteen-year-old mechanic for that sum. It was late that afternoon before he found one who, after some hesitation, agreed to do it. Then he looked at the small, dirty room she showed him, at her untidy, slatternly person, and decided that he would not live there. He came out into the street again. Henry was facing the big problem. How was he to live on an income too small? Apparently his mind went, with the precision of a machine, directly to the answer. "When your reasonable expenses exceed your income, increase your income." Simple. He knew that after he had finished his day's work at the shops there would be a margin of several hours a day left to him. He would have to turn them into money. That was all. He returned to a clean boarding house he had visited earlier in the day, paid three dollars and a half in advance for one week's board, and ate a hearty supper. Then he went to bed. CHAPTER IV AN EXACTING ROUTINE Meantime back in Greenfield there was a flurry of excitement and not a little worry. Henry did not return from school in time to help with the chores. When supper time came and went without his appearing Margaret was sure some terrible accident had occurred. A hired man was sent to make inquiries. He returned with the news that Henry had not been in school. Then William Ford himself hitched up and drove about the neighborhood looking for the boy. With characteristic reserve and independence Henry had taken no one into his confidence, but late that night his father returned with information that he had been seen taking the train for Detroit. William Ford knew his son. When he found that Henry had left of his own accord he told Margaret dryly that the boy could take care of himself and there was nothing to worry about. However, after two days had gone by without any word from Henry his father went up to Detroit to look for him.
