The first day of November there were employed here 115 men. There are at this point, besides the shops and saw mill above mentioned, 2 small offices, 1 boarding-house, 2 carpenters' shops, 2 powder-houses, 1 temporary blacksmith's shop, 1 temporary horse-stable, 3 sheds, 1 engine-house, 1 barn, 1 instrumental station-house (all used by the State,) and 2 cottages; 6 first-class shanties, 13 common shanties, 10 temporary shanties, 1 store under school-room; with 1 cottage, 1 old store and 8 shanties, built by H. Haupt & Company, which are rented. The cost of the shanties at the East End, excluding the Deerfield Dam, was, in July, 1866, . . . . . . . $28,052 94 In November, 1866, . . . . . . . 31,688 99 The rents at the East End received by the State from shanties are, . . . . . . . 1,698 00 per annum. All rents are collected monthly. A resident engineer was stationed at the East End in charge of the work. The progress of the excavations at the East End heading for the year ending December, 1866, has been 569 feet; at the rate of 47.42 per month. The progress during the six months ending May, 1866, was 338 feet; an average per month of 56 feet 4 inches. One week was lost in June in introducing the machine-drills, in consequence of which the progress that month was reduced to 50 feet 6 inches. During the five months ending November 30, the progress has been 219-1/2 feet; being an average of 43.9 feet per month. It will be seen by the table, that in July, the first month after the introduction of the drill machines, the progress attained was only 26.5 feet. As the men became better acquainted with them, the progress was increased to 48 feet in August, and in September it rose to 54.5, having nearly attained the average progress of the six months preceding their introduction. Had there been an adequate supply, there can be little doubt that the progress would have continued to increase, and would have shown the superiority of the machine-drill over hand-labor; but the supply fell off, and the progress in October was reduced to 34 feet and 6 inches. _Table showing the progress at East End Heading, from November 1, 1865, to January 1, 1867._
