_Resolved_, That the direction of the engineering operations within the Hoosac Tunnel after the location of the line is adopted, and plans perfected for the same, be left with the contractor, excepting the measurements for monthly and final estimates and the final acceptance of the work. 1855, July 18. Mr. Serrell having proposed to subscribe the sum of $600,000 (less the amount of the new subscription made by others,) provided the company would make such allowances as would enable him to dispose of the proposed issue of $900,000 of bonds advantageously, the directors voted to add $300,000 to the contract prices of the work, and that said $900,000 bonds as provided by the contract should be issued as soon as authorized by the stockholders, and placed in bank by the trustees to the credit of such persons as shall deposit against the same cash or railroad iron equal in value to sixty-five cents on the dollar. The said bonds to be taken by said Serrell at par and so estimated in his contract. At this time sixteen hundred and thirty-five shares of new stock had been subscribed, amounting to $163,500. The trustees alluded to in the foregoing vote were selected by a committee appointed for the purpose, and with power to execute to them a mortgage. They were J. V. C. Smith, Paul Adams and John G. Davis, all of Boston. The mortgage was executed, and is known in the history of the road as the "Smith mortgage." A resolution explanatory of this transaction was passed August 16, 1855, in the following words:-- "_Resolved_, That, whereas by the terms of the provisions of the resolution of July 18, 1855, by which it is provided that the bonds of the company to be issued, are to be placed in bank, &c.; therefore, as explanatory thereto, be it _Resolved_, That it is not intended thereby to prevent the operation of the contract, but that the said bonds are to be delivered to Serrell & Co., on the warrant of the engineer, countersigned by the president and treasurer, whenever the engineer shall draw therefore on monthly or final estimates." 1856, February 7. The president reported to the directors that a contract had been redrafted and concluded with Messrs. Serrell, Haupt & Co., which was read, accepted and ratified, and the committee discharged. This contract was probably dated January 31, 1856, but the Committee have not been able to find it among the papers of the corporation. 1856, May 22. The directors voted, that in case Messrs. Serrell, Haupt & Co., would enter into an agreement to carry on the work of the Troy and Greenfield Railroad Company, in compliance with the terms and conditions of the loan Act, until 2,000 feet of the tunnel should be completed, the corporation would substitute bonds instead of stock in all payments to be made on account of work to be done to that time.
