For transportation of the mails from New York to Liverpool and back, $858,000; and that the proviso contained in the first section of the act entitled "An act to supply deficiencies in the appropriations for the service of the fiscal year ending the 30th of June, 1852," approved the 21st of July, 1852, be, and the same is hereby, repealed: _Provided_, That Edward K. Collins and his associates shall proceed with all due diligence to build another steamship, in accordance with the terms of their contract, and have the same ready for the mail service in two years from and after the passage of this act; and if the said steamship is not ready within the time above mentioned, by reason of any neglect or want of diligence on their part, then the said Edward K. Collins and his associates shall carry the United States mails between New York and Liverpool from the expiration of the said two years, every fortnight, free of any charge to the Government, until the new steamship shall have commenced the said mail service.

The proposition was in the following terms: WASHINGTON, _March 6, 1846_. E.K. Collins and his associates propose to carry the United States mail between New York and Liverpool twice each month during eight months of the year and once a month during the other four months for the sum of $385,000 per annum, payable quarterly. For this purpose they will agree to build five steamships of not less than 2,000 tons measurement and of 1,000 horsepower each, which vessels shall be built for great speed and sufficiently strong for war purposes. Four of said vessels to be ready for service in eighteen months from the signing of the contract. The fifth vessel to be built as early as possibly practicable, and when not employed in the mail service to be subject to the orders of the Government for carrying dispatches, for which service a fair compensation is to be paid. Contract to be for the term of ten years. It is also proposed to secure to the United States the privilege of purchasing said steamships whenever they may be required for public purposes, at a fair valuation, to be ascertained by appraisers appointed by the United States and by the owners.
