The probable outlay of an experiment upon a scale equal to fifty miles of telegraph, and equal to a circuit of double that distance, is estimated at $30,000. Two-thirds of this expenditure will be for material, which, whether the experiment shall succeed or fail, will remain uninjured, and of very little diminished value below the price that will be paid for it. The estimates of Professor Morse, as will be seen by his letter, marked 9, amount to $26,000; but, to meet any contingency not now anticipated, and to guard against any want of requisite funds in an enterprise of such moment to the Government, to the people, and to the scientific world, the committee recommend an appropriation of $30,000, to be expended under the direction of the Secretary of the Treasury; and to this end submit herewith a bill. It is believed by the committee that the subject is one of such universal interest and importance, that an early action upon it will be deemed desirable by Congress, to enable the inventor to complete his trial of the invention upon the extended scale contemplated, in season to furnish Congress with a full report of the result during its present session, if that shall be practicable. All which is respectfully submitted. FRANCIS O. J. SMITH, JAS. M. MASON, S. C. PHILLIPS, JOHN T. H. WORTHINGTON, SAMUEL CUSHMAN, WM. H. HUNTER, JOHN I. DE GRAFF, GEORGE W.

HALL OF THE FRANKLIN INSTITUTE, _Feb. 8, 1838_. _Report of the Franklin Institute Philadelphia._ The sub-committee, from the committee of science and arts, appointed to examine the electro magnetic telegraph of Professor Samuel F. B. Morse, report: That this instrument was exhibited to them in the hall of the Institute, and every opportunity given by Mr. Morse and his associate, Mr. Alfred Vail, to examine it carefully, and to judge of its operation; and they now present the following as the result of their observations: * * * * The operation of the telegraph, as exhibited to us, was very satisfactory. The power given to the magnet at the register, through a length of wire of ten miles, was abundantly sufficient for the movements required to mark the signals. The communication of this was instantaneous. The time required to make the signals was as short at least, as that necessary in the ordinary telegraphs. It appears to this committee, therefore, that the possibility of using telegraphs upon this plan, in actual practice, is not to be doubted; though difficulties may be anticipated, which could not be tested by the trials made with the model.
