Increase of reputation and influence brought Mr. Sibley opportunities for office. He was elected by the Democrats Sheriff of Monroe County in 1843 when he removed to Rochester; but his political career was short, for a more important matter was occupying his mind. From the moment of the first success of Professor Morse with his experiments in telegraphy, Mr. Sibley had been quick to discern the vast promise of the invention; and in 1840 he went to Washington to assist Professor Morse and Ezra Cornell in procuring an appropriation of $40,000 from Congress to build a line from Washington to Baltimore, the first put up in America. Strong prejudices had to be overcome. On Mr. Sibley's meeting the chairman of the committee having the matter in charge, and expressing the hope that the application would be granted, he received for answer: "We had made up our minds to allow the appropriation, when the Professor came in and upset everything. Why! he undertook to tell us that he could send ten words from Washington to Baltimore in two minutes. Good heavens! Twenty minutes is quick enough, but two minutes is nonsense. The Professor is too radical and visionary, and I doubt if the committee recommend the sum to be risked in such a manner." Mr. Sibley's sound arguments and persuasiveness prevailed, though he took care not to say what he believed, that the Professor was right as to the two minutes. Their joint efforts secured the subsidy of $40,000. This example stimulated other inventors, and in a few years several patents were in use, and various lines had been constructed by different companies. The business was so divided as to be always unprofitable. Mr. Sibley conceived the plan of uniting all the patents and companies in one organization. After three years of almost unceasing toil, he succeeded in buying up the stock of the different corporations, some of it at a price as low as two cents on the dollar, and in consolidating the lines which then extended over portions of thirteen States. The Western Union Telegraph Company was then organized, with Mr. Sibley as the first president. Under his management for sixteen years, the number of telegraph offices was increased from 132 to over 4,000, and the value of the property from $220,000 to $48,000,000.
