At once he visited the young lady, and told her of his great success. She listened eagerly, and then said, "Yes, I understand this; but surely, if all stamps had a _date_ put upon them, they could not at a future time be used without detection." His spirits fell. He confessed afterward that, "while he felt pleased and proud of the clever and simple suggestion of the young lady, he saw also that all his more elaborate system, the result of months of toil, was shattered to pieces by it." What need for four hundred holes in a die, when a single date was more effective? He soon worked out a die with movable dates, and with frankness and honor presented it before the Government officials. They saw its preferableness: the new plan was adopted by Act of Parliament; the old stamps were called in and new ones issued; and then the young inventor was informed that his services as Superintendent of Stamps, at three thousand dollars a year, were not needed. But surely the Government, which was to save a half million dollars a year, would repay him for his months of labor and thought! Associations, like individuals, are very apt to forget favors, when once the desired end is attained. The Premier had resigned; and, after various promises and excuses, a lawyer in the Stamp Office informed him that he made the new stamp of his own free will, and there was no money to be given him. "Sad and dispirited, and with a burning sense of injustice overpowering all other feelings," says young Bessemer, "I went my way from the Stamp Office, too proud to ask as a favor that which was indubitably my right." Alas! that he must learn thus early the selfishness of the world! But he took courage; for, had he not made one real invention? and it must be in his power to make others. When he was twenty-five he produced a type-casting machine; but so opposed was it by the compositors, that it was finally abandoned. He also invented a machine for making figured Utrecht velvet; and some of his productions were used in the state apartments of Windsor Castle. A little later his attention was accidentally called to bronze powder, he having bought a small portion to ornament his sister's album. The powder, made in Germany, cost only twenty-two cents a pound in the raw material, and sold for twenty-two dollars. Here was a wonderful profit. Why could he not discover the process of making it? He worked for eighteen months, trying all sorts of experiments, and failed. But failure to a great mind never really means failure; so, after six months, he tried again, and--succeeded. He knew little about patents, had been recently defrauded by the Government; and he determined that this discovery should be kept a secret. He made a small apparatus, and worked it himself, sending out a travelling-man with the product. That which cost him less than one dollar was sold for eighteen. A fortune seemed now really within his grasp.
