This act was not passed to further the personal interests of the corporators, nor for the advancement of commercial interests, nor for the convenience of the general public, alone; but in addition to these the interests, present and future, of the Government, as such, were to be subserved. A great highway was to be created, the use of which for postal, military, and other purposes was to be secured to the Government "at all times," but particularly in time of war. Your committee deem it important to call especial attention to this declared object of this act, to accomplish which object the munificent grant of lands and loan of the Government credit was made. To make such a highway and to have it ready at "all times," and "particularly in time of war," to meet the demands that might be made upon it; to be able to withstand the loss of business and other casualties incident to war and still to perform for the Government such reasonable service as might under such circumstances be demanded, required a strong, solvent corporation; and when Congress expressed the object and granted the corporate powers to carry that object into execution, and aided the enterprise with subsidies of lands and bonds, the corporators in whom these powers were vested and under whose control these subsidies were placed, were, in the opinion of your committee, under the highest moral, to say nothing of legal or equitable obligations, to use the utmost degree of good faith toward the Government in the exercise of the powers and disposition of the subsidies. Congress relied for the performance of these great trusts by the corporators upon their sense of public duty; upon the fact that they were to deal with and protect a large capital of their own which they were to pay in money; upon the presence of five directors appointed by the President especially to represent the public interests, who were to own no stock; one of whom should be a member of every Committee, standing or special; upon the commissioners to be appointed by the President, who should examine and report upon the work as it progressed; in certain cases upon the certificate of the chief engineer, to be made upon his professional honor; and lastly, upon the reserved power to add to, alter, amend, or repeal the act.
