The existence of the mortgages to the State were of course well known to the contractors. They were given in pursuance of laws passed by the legislature, and for security of the payments received by the contractors for their services. The right of the Commonwealth to take possession of the railroad under the mortgages, must have been well understood. Further, the corporation, in surrendering the road to the State, did no injury to the contractors, for the act of surrender did not take place until after the contractors had suspended work upon both road and tunnel, and practically abandoned the enterprise; thus leaving to the State the alternative, either to take possession of the work and complete the road and tunnel, or to abandon it; and, in addition to the loss of the advances already made, forego the anticipated benefits of an additional avenue for Western traffic. The treasurer's books do not show any settlement between Haupt and Company and the corporation. The account standing upon the ledger shows a large balance against the contractors; but the Committee are informed that subsequent to May 30, 1863, a settlement was made upon the basis of Mr. Stevenson's report (see Appendix A,) and that Mr. Haupt received, in conformity with the contract of H. Haupt & Co. with the Troy and Greenfield corporation, payment for all labor done and material furnished by said H. Haupt & Co., for the corporation, and that all matters between the parties have been adjusted. Although the accounts between the contractors and the corporation are understood to be settled, it may be interesting to examine the account of the Commonwealth with the enterprise and compare the value of the work done by the contractors at the time of its abandonment by them, with the payments made to them therefore, from the treasury of the State.
