required to purchase the same, but the state treasurer shall withhold an equal amount of state scrip at par in lieu thereof. The semi-annual payments of the coupons, with the balance of the income from the lease of the Southern Vermont Railroad, shall be collected by or paid to the state treasurer, who shall therefrom pay the interest on the two hundred thousand dollars of five per cent. scrip herein authorized to be issued, and shall pay the balance to the commissioners of the sinking fund of the Troy and Greenfield Railroad loan, to be by them from time to time invested as is now by law required. The Troy and Greenfield Railroad Company shall, as soon as may be after the passage of this act, procure from the legislature of the slate of Vermont the requisite authority for purchasing, holding and mortgaging to the Commonwealth the franchise, railroad and property of the Southern Vermont Railroad Company, according to the provisions of this act; and in case such authority shall not be granted, and any want of security by reason thereof accrue to the Commonwealth, the governor and council shall withhold from the Troy and Greenfield Railroad Company portions of scrip constituting the last deliveries to be made on the completion of the tunnel, to such amount, not exceeding two hundred thousand dollars, as may be required for further security. SECT. 9. All acts and parts of acts inconsistent herewith, are hereby repealed: _provided_, _however_, that such repeal shall not, and nothing contained in this act shall, have effect or be construed in anyway to release or impair any security which the Commonwealth now has or may hereafter have by force of the bond and mortgage now held by the Commonwealth on the franchise, railroad and property of the Troy and Greenfield Railroad Company. _Approved April 4, 1860._ [1862.--Chapter 156.] AN ACT providing for the more speedy completion of the Troy and Greenfield Railroad and Hoosac Tunnel. _Be it enacted, &c., as follows:_ SECT. 1.
