220 Reports of the Inspectoes of Mines. [Off. Doc. moth vein forty-three feet, distance from bottom slate of Mammoth vein to top slate of Seven-foot two hundred and eighty -nine feet, and the slope is now sunk a distance of two hundred and thirty-one feet in the Seven- foot vein, which is 10' 9 ' thick having 9' of coal. At one hundred and twelve feet from knuckle of No. 5 slope the Skidmore vein was cut 5' 6" thick having 3' of coal. Dip of these veins seven and one-half degrees south. Two additional bore-holes were put down (making eleven in all) through which to convey silt and water to fill the space made by the mining of the Mammoth vein. The first mention made of these bore-holes was in my report for 1887, and this method of filling up the mine excavations in connection with Kohinoor colliery has been in operation ever since, and has been effectual to the extent that it has checked the surface subsidence and i^revented the damaging of house properties. Mr. John L. Williams, division superintendent of the P and R. Coal and Iron Company's collieries in my district, who first conceived the idea of filling up mine openings by bore-holes, is very jubilant over his success, and sev- eral prominent mining men have inspected Kohinoor colliery with a view of adopting the same means of filling mine excavations where practicable, and I am informed by reliable autliority that it has been commenced in the Wilkesbarre mining district. At Indian Ridge colliery a new underground shaft has been sunk to the Buck Mountain vein with three compartments, two hoistings 11' 8"x7' and one pumping 11' 8 "x3', length of shaft one hundred and seventytwo feet. The vein was cut thirteen feet thick on east side of shaft and six feet on the west side and is very much confused, but in trial holes driven north and south the vein is in its normal condition thirteen feet thick with ten feet of cotd. The trial hole north passed through a dirt fault ten yards long, beginning about forty yards from shaft. At forty feet from top of shaft the Skidmore vein was cut 7' 8" thick with 6' 4" of coal. At sixty-six feet from top of shaft the Seven-foot vein was cut 6' 11 " thick with 6' 4 " of coal. A tunnel two hundred and eighty-nine feet long was driven west from bottom of Buck Mountain subterraneous slope through the fault and cut the Seven-foot vein 7' 10" thick with 6' 4" of coal. Two bore-holes have been drilled to conduct the ropes from hoisting engine on surface to underground shaft. At Knickerbocker colliery a new slope (called No. 4) has been sunk in the top member of the Mammoth vein, a distance of three hundred and sixty-two feet below the old water level drift, making a total distance from surface to new gangways eight hundred and twenty -six feet. A pair of engines, direct acting, have been (erected at top of this slope, cylinders thirty inches and stroke sixty inches. A tunnel from top split, first lift, east gangway (at breast one hundred and five), Avas extended sixty-six feet through saddle from bottom split; total length of tunnel one hundred and sixty-two feet, thickness of bottom split 5" of coal. 6' " with 4'
No. 12.] Sixth Anthracite District. 221 At Shenandoah City colliery the main hoisting" shaft was south from the Mammoth to the Buck Mountain vein, a distance of one hundred and sixty feet ; distance from surface to the Mammoth vein, two hundred and ninety-four feet ; total length of shaft four hundred and fifty -four feet. Buck Mountain was cut 12' 1 " thick with 9' 4' of coal. An airway three hundred feet long was driven from the shaft level east gang-way to the Plank Ridge old Buck Mountain workings. At West Shenandoah colliery the hoisting slope in Buck Mountain vein is being- extended, and is now down one hundred and seventy yards below the third lift. At Turkey Run colliery a new underground slope is being sunk from the head of old Mammoth vein slope through rock and in the Seven-foot vein. From the knuckle of slope to bottom slate of bottom split is forty-six feet. From bottom slate of bottom split to top slate of Seven- foot vein is two hundred and twenty-five feet, the estimated leng-th of slope is about ten hundred and twenty-one feet from the knuckle to a point three hundred and forty-five feet below West Shenandoah colliery third lift gangway. At Hammond colliery a slojê has been sunk in the Buck Mountain vein to second lift below water level, a distance of two hundred and eighty -four and one-third yards, and timbered with a nineteen foot collar, twenty -three feet, and eight feet of rail. An airway eighty-nine yards long and twelve feet wide has been driven from second lift west gang-way to first lift gangway. An airway one hundred and three yards long and twelve feet wide from second lift west gangway to first lift gangway. An airway ninetyone yards long- and twelve wide from first lift Buck Mountain, to No. 1 West Connor drift is in course of construction. The new Buck Mountain slope is used for lowering and hoisting- men, and material, such as timber rails, etc. At Girard colliery a tunnel thirty-one yards long (called No. 4 west) from second lift Skidmore vein north dip west gangway to Mammoth vein north dip. A monkey tunnel thirty-two yards long- has been driven (nearly over above main west tunnel No. 4) from monkey gangway Skidmore vein, north dip, to Mammoth vein, dip of vein 75° north. A tunnel (No. 4 east) nineteen yards long- has been driven north (from a point nineteen hundred and sixty feet east of Tender slope) from Skidmore vein east gangwa\% north dip, to Mammoth vein, north dip. A monkey tunnel fifty-eight yards long (called No. 4 east), (and nearly over No. 4 main east tunnel) has been driven from monkey g-angway in Skidmore vein to south dip of Mammoth vein. A monkey tunnel (called No. 5 east) nineteen and tAvo-thirds yards long has been driven from monkey g-angway, Skidmore vein, north dip, to Mammoth vein, north dip. Section No. 1 east tunnel has been extended seventy-one yards to Buck Mountain vein, south dip, making- total length of tunnel from Skid-
