Y.Tthus forming with the Fiteliburg and Vermont & Mass. another through line to the west. It was compar¬ atively an easy road to build, except for the great moun¬ tain barrier that separated the valleys of tiie Deertiehl and Iloosae. One of the most important questions which arose when the tunnel was projected concerned the geological character of the mountain. Prof. Ed¬ ward Ilichcock of Amherst College, who had been studying the formation of the Hoosac for many years, came before the legislative committee and gave his opinion—said that he had been examining the moun¬ tain with special reference to a tunnel, and in his opin¬ ion there would scarcely anything else lie found but mica slate with occasional seams of quartz. The ground he thought would tie found easy to drill, and that put very little would lie encountered which would require arching. The prognosis of Prof. Hitchcock was in most particulars found strikingly correct. It was modified in some respects however, as at the west end a now and unexpected formation was encountered, occasion¬ ing much delay and a heavy additional expense. The reader will notice by referring to the profile of the mountain, that directly above the tunnel there are two summits, with a wide valley intervening, the west summit being 1,718 feet above the tunnel, the east 1,429 feet. A great portion of the line over the mountain is covered with forests, the earth averaging about 10 feet deep. In portions of the valley the land is swampy. The rock through which the tunnel passes is principally mica slate, with occasional veins of quartz. Now and then, in portions of the tunnel, rock was encountered, which could not be distinguished from granite, and often exceeded it in hardness. The stratilicat.ion dips eastward at an angle of from 60 to 80 degrees from the horizontal, changing two * % ©■ 8 HISTORY OF THE miles from the east end to a dip of from 22 to 30 degrees, which continues for the next half or three-quarters of a mile. At this point the dip changes to the westward, and lies at an angle of from 20 to 30 degrees. In 1851 work was tirst begun on the tnnnel with a ponderous and costly boring machine, with which it was the intention of the company to cut or bore a hole through the mountain the full size of the tunnel. This, together with other machines of a similar character which were tried, proved a failure, and the company, finding the undertaking more formidable than had been imagined, ceased work until 1854. At this time the State voted a loan of $2,000,000, and took a mortgage on the company's property. The work went slowly on until 1861, when the funds gave out, and in 1862 the State foreclosed its mortgage at the desire of the com¬ pany. Commissioners were then appointed by the State to prosecute the work, and made new appro¬ priations. After six years' management by Commis¬ sioners, the Legislature, weary of making constant ap¬ propriations, and, seeing small results, authorized the Governor and Council to make a contract with some one for the entire work of completing the tunnel. Soon after, a contract was made with Messrs. F. Shanley & Co. of Montreal. Up to this time—January, 1869—the amount of work done by various contractors and State Commissioners was as follows: East end, advanced 5,283 feet; west end, 4,055 feet; west shaft sunk to grade, 318 feet; central shaft sunk to a depth of 583 feet. Thus it will be seen that up to this time but little more than one-third of the work necessary for the com- I pletion of the tunnel had been done. And the actual 1 amount of money expended by the State and contractors I thus far, not reckoning interest, was more than $7,- I 000,000. The contract made with the Messrs. Shanley required them to complete the tunnel, of which there still re¬ mained to be opened 15,743 feet; the central shaft to be ©■ « H OOS AO TUNNEL 9 sunk to grade, a depth, in addition to what had already been done, of 445 feet, for the sum of 34,594,268. Under this contract the work was successfully and vig¬ orously prosecuted. Obstacles and difficulties even greater than any that had heretofore been encountered through the indomitable energy and perseverance of the contractors were overcome, and, on February 9th, 1875, the first train of cars passed through HoosacMountain.

Up to 1865 the drilling had been done by hand power, and ordinary black powder used in blasting, by which means the tunnel advanced but slowly. About this time the Commissioners became interested in machine drills, driven by compressed air, they at this time being successfully used on the Mount Genis Tunnel, which was being built under the Alps, between Italy and France. The first air compressors used on the tunnel were built by James Hunter & Son of North Adams, Mass, These, together with a large number manufactured by the Bur¬ leigh Rock and Drill Company, were used up to the time of the completion of the tunnel. HOLMES. 2 10 HISTORY OF THE [Burleigh Air Compressor.] The Deerfield river, a stream which flows down through the Deerfield valley, passing near the eastern entrance o'f the tunnel, was dammed at a point three- quarters of a mile above, and the water brought by canal, with a fall of 30 feet, to within a short distance of the tunnel. It was at first thought that sufficient power could lie obtained at this point necessary to run the drilling machines and other machinery used in carry¬ ing on the work at the east end, central shaft and the west end. The air compressors being located at the east end, it was proposed to run a line of iron pipes from them, over the mountain, to the central and west end sections, through which to convey the compressed air, thereby supply power necessary to carry on the work at these points. The dam supplied, however, sufficient power for the east end work only, and at the HOOSAO TUNNEL. 11 central and west end sections steam power was em¬ ployed. Tlie drilling machine tirst used in 186G was complicated, costly, and failed to do the work. A short time afterward, a company was formed, known as the Burleigh Rock Drill Company, at Fitchburg, Mass., who perfected a machine which was lighter, less expen¬ sive, more easily repaired, and proved far more effective. These machines were used up to the time of the com¬ pletion of the tunnel. In the headings, eight drilling machines were kept constantly at work, except when the men were employed in blasting and clearing away the rock. They were mounted on frames, or what were more commonly termed a drill carriage on wheels, two of which were used, each mount¬ ing four drills. The machine consisted simply of a cyl¬ inder and piston, the drill being faste ed to the end of the piston, which moved back and forth in the cylinder, propelled and operated by compressed air, like the pis¬ ton of an ordinary steam engine. They were arranged on the carriages so as to b5 >±< 1. Application of Wings. •>. Tool House. 3. Caboose, -i. Ai plication of Plow t<. Car. 5.

Indianapolis and Cincinnati Railroad, 1 Master Mechanic's Office, Cincinnati, Ohio, November 28,1865. ) Mr. C. L. Heywood, Boston, Mass. Your letter requesting me to give an opinion relative to the merits of your Snow Plow and Scraper, is received. It affords me pleasure to say that while engaged on the Fitchburg Railroad I had an opportunity to examine it carefully, and witness its operation. It is the best ma¬ chine I hâve ever seen, not only for clearing ice and snow from the track, but at the same time removing it deep enough so that the flanges suffer no impediment whatever. The great speed at which it can be run with perfect safety, gives.it an advantage over any other ma¬ chine nowused forthat purpose. Its simplicity and du¬ rability renders it a desirable machine for any railroad obstructed by Snow or Ico. Yours truly, H. M. BRITTON, Master Mechanic.
