QUARTZYTES AND SANDSTONES. 69 



torn there is a greenish-gray and mottled rock, which is so seamy and 

 has so much iron oxide on it that it is worthless. The stone of the 

 quarry beds is nearly all of a red or deep brown color, and fine- 

 grained, but variations in texture and in shade of color from bed to 

 bed and from point to point in the same bed, is observed here as in 

 all of these Medina quarries. One main system of joints runs verti- 

 cally east and west, but somewhat irregular in its course. A steam 

 pump is used for raising the water. The stone is carted to the canal. 

 The product of these quarries consists of building stone, which is 

 sold in the rough generally, and is used for house trimmings and for 

 rock-ashlar. The stone for street work is flagging and platforms, 

 some of which are as much as 20 feet in length and having smooth 

 natural faces. Stone for curbing, crosswalks and natural face blocks 

 are also produced. A large force of men is employed, and the out- 

 put of the quarry is large. 



McCormick. — A. J. McCormick's quarry is north-east of Horan's, 

 and separate from it by a property line only. The south front, or 

 face of the quarry, has an eastern and western course, and is on a line 

 with Horan's north limit. On the east of this main quarry there is 

 a second and smaller opening, also belonging to McCormick. It was 

 opened in 1871. The eastern opening is worked at times, for paving 

 stone principally. The main quarry has an estimated area of 

 four to five acres. The stripping here is red, sandy earth, 

 with scattering masses of sandstone imbedded in it, and is five 

 feet thick. Under it is an inferior, shaly, thin-bedded, reddish sand- 

 stone, three feet thick, suitable for common wall stone only. Then 

 come the quarry beds which are from 2 inches to 6 feet thick, 

 together amounting to 15 or 18 feet. The thick beds can be riven 

 into platforms, flagging stone, etc., if so wanted, or are sold for build- 

 ing. The dip of the beds, as at all of these Medina quarries, is south 

 and at a very small angle, and hence as the quarry work moves south, 

 successive beds appear at the top. The joints are regular ; one sys- 

 tem east and west, being vertical and one system north-east and south- 

 west, but more irregular. The faces of these joints or seams are in 

 part coated with pyrite. The stone is red, with a little of it varie- 

 gated. No derricks are used. The water is raised by steam power. 

 There is a quarry dock on the canal a quarter of a mile away. The 

 product is largely for street work, such as curbstone, crosswalk-stone, 

 flag-stone and paving blocks. Some stone for rock-faced ashlar, for 

 buildings and for house trimmings, is sold, mostly in the rough. It is
