To read the marks, count the points at the bottom of each line. It will be perceived that two points come first, separated by a _short_ interval from the next point. Set 2 beneath it. Then comes one point, likewise separated by a _short_ interval. Set 1 beneath it. Then come five points. Set 5 beneath them. But the interval in this case is a _long_ interval: consequently, the three numbers comprise the whole number, 215. So proceed with the rest, until the numbers are all set down. Then, by referring to the telegraphic dictionary, the words corresponding to the numbers are found, and the communication read. Thus it will be seen that, by means of the changes upon _ten_ characters, all words can be transmitted. But there are _two points_ reversed in the lower line. These are the _eleventh_ character, placed before a number, to signify that it is to be read as a _number_, and not as the representative of a word. No. 6. Mr. SMITH, from the Committee on Commerce, made the following Report, April 6th, 1838. _The Committee on Commerce to whom the subject was referred, have had the same under consideration, and report:_ On the 3d of February, 1837, the House of Representatives passed a resolution requesting the Secretary of the Treasury to report to the House, at its present session, upon the propriety of establishing a system of telegraphs for the United States. In pursuance of this request, the Secretary of the Treasury, at an early day after the passage of said resolution, addressed a circular of inquiry to numerous scientific and practical individuals in different parts of the Union; and, on the 6th of December last, reported the result of this proceeding to the House. This report of the Secretary imbodies many useful suggestions on the necessity and practicability of a system of telegraphic despatches, both for public and individual purposes; and the committee cannot doubt that the American public is fully prepared, and even desirous, that every requisite effort be made on the part of Congress to consummate an object of so deep interest to the purposes of Government in peace and in war, and to the enterprise of the age. Amid the suggestions thus elicited from various sources, and imbodied in the before-mentioned report of the Secretary of the Treasury, a plan for an electro magnetic telegraph is communicated by Professor Morse, of the University of the city of New York, pre-eminently interesting, and even wonderful. See Report, No. 2.
