With the view of obtaining information in regard to “the propriety of establishing a system of telegraphs for the United States,” in compliance with the request contained in the annexed resolution of the House of Representatives, adopted at its last session, I will thank you to furnish the Department with your opinion upon the subject. If leisure permits, you would oblige me by pointing out the manner, and the various particulars, in which the system may be rendered most useful to the Government of the United States and the public generally. It would be desirable, if in your power, to present a detailed statement as to the proper points for the location, and distance of the stations from each other, with general rules for the regulation of the system, together with your sentiments as to the propriety of connecting it with any existing department of the Government, and some definite idea of the rapidity with which intelligence could ordinarily, and also in urgent cases, be communicated between distant places. I wish you to estimate the probable expense of establishing and supporting telegraphs, upon the most approved system, for any given distance, during any specified period. It would add to the interest of the subject if you would offer views as to the practicability of uniting with a system of telegraphs for communication in clear weather and in the day time, another for communication in fogs, by cannon, or otherwise; and in the night, by the same mode, or by rockets, fires, &c. I should be gratified by receiving your reply by the first of October next. LEVI WOODBURY, _Secretary of the Treasury_. No. 2. _Letter from S. F. B. Morse, to the Secretary of the Treasury._ NEW YORK CITY UNIVERSITY, _Sept. 27, 1837_.
