The facts and reasonings which have now been submitted, satisfy the committee that it is important that the government should lose no time in occupying, with a telegraph of its own, the ground between Baltimore and New York. The committee look to the probability that the line will afterwards he progressively extended northwardly, southwardly, and westwardly, on routes the business and correspondence on which shall justify and require telegraphic facilities of communication. Apart from the post office power, the government undoubtedly possesses the authority to establish the telegraph for its own use in the transmission of official orders and communications. On this ground, as well as on that growing out of the post office power, the committee deem the constitutionality of the measure incontrovertible. The committee might easily add to the views and arguments which they have now presented, others of a highly commanding character—especially those which relate to the extreme value of which the magnetic telegraph would be in the emergencies of war, and its singular adaptedness to render our system of government easily and certainly maintainable over the immense space from the Atlantic to the Pacific, which our territory covers. Doubt has been entertained by many patriotic minds how far the rapid, full, and thorough intercommunication of thought and intelligence, so necessary to a people living under a common representative republic, could be expected to take place throughout such immense bounds. That doubt can no longer exist. It has been resolved and put an end to forever by the triumphant success of the electro magnetic telegraph of Professor Morse, as already tested by the government. The fact that a bill has been long pending in the House, introduced by the Committee on Commerce, for the extension of the telegraph from Baltimore to New York, renders it unnecessary for this committee to report a bill. Without pronouncing positively on the sufficiency of the provisions of that bill, the committee consider the whole subject worthy the prompt attention of Congress. Having thus presented their views on the subject referred to them, the committee beg to be discharged from its further consideration.
