The Act of April 4, 1860, defines the size the tunnel to be 14 feet wide and 18 feet high. If this means excavation and not completed tunnel, then the room required for the ballast and drainage would reduce the height to about 16 feet above the rails; a size absurdly small enough to be regarded as certainly not above the minimum intended by the Act. The same Act provides that $30 per foot shall be allowed on account of heading, and $20 on account of the enlargement, making $50 per foot for the completed tunnel; $50,000 of the first advance may therefore be considered as on account of the first 1,000 feet of completed tunnel, and the remainder, say $50,000, on account of the road which had been then completed west of the tunnel. The second delivery of scrip was on account of the tunnel, and under the provisions of the' Act of 1859, which provides that $50,000 may be advanced upon the completion of 1,000 feet of heading. The heading was done and $49,777.78 delivered October 4, 1859. The third delivery of scrip was under the provisions of the same Act, and was on account of grading three miles of road, in detached pieces, near Greenfield. For this, $50,222.22 was delivered January 3, 1860. The fourth delivery was under the same Act, and for completing the second 1,000 feet of tunnel, for which $30,222.22, was delivered March 1, 1860. An Act changing the terms of the loan was passed April 4, 1860. Section 2 divides the scrip remaining undelivered, as follows: "No further deliveries of scrip shall be made to said company upon the conditions authorized in former Acts, but the undelivered portions of the loan of two millions of dollars authorized by chapter two hundred and twenty-six of the Acts of eighteen hundred and fifty-four, amounting to one million seven hundred and seventy thousand dollars, shall be divided and apportioned between the railroad and tunnel, and for the construction of each, respectively: 'six hundred and fifty thousand dollars for the completion of the unfinished portion of railroad extending from the eastern terminus of said road near Greenfield, to within half a mile of the eastern end of Hoosac Tunnel."
