"The transportation of the ocean mails, with the greatest possible advantage to the important interests of the country at large, is an object of paramount importance; but which, however desirable, can only be effected at great expense. It is a matter of comparatively small moment at what precise time this expense is to be paid, provided that the end in view can be attained with certainty. The temporary loan of a part of the means required, under proper securities for reimbursement, appears to be the readiest mode by which the purpose can be effected. How is this security to be acquired? Simply, by taking due care that the funds advanced shall be faithfully and honestly applied to the object for which they are intended, and then holding a lien upon the ships, for the construction of which they are appropriated, in such a manner as to insure the reimbursement of the sums advanced in the form of mail service or money; or, should circumstances require, of ships suitable for national purposes, as war steamers. This has been done. In all cases the contractors for the transportation of the ocean mails, have been required to cause their ships to be built and equipped under the immediate superintendence of experienced naval officers and under the direction of naval constructors, appointed by the Government, in such manner as to be convertible, at the smallest possible expense, into war steamers of the first class.
