Mance: Quarry Industrij of Southern Indiana 31 



The quarry north of the mills on the site of the old Morton 

 C. Hunter quarry is being opened again, new floors are being 

 stripped, and two new derricks are being installed at this point. 

 In this quarry the upper layer of the stone has weathered very 

 irregularly, owing to the fact that there is no covering of Mitchell 

 limestone. The appearance of the surface of the rock is in marked 

 contrast to the upper layers in the quarries already mentioned. 



Hunter Brothers' mill and quarry, opened in 1893, are located 

 about one-half mile north and east of the Consolidated Stone 

 Companj^'s plant. The openings are made in the north side of 

 a ridge that nearly crosses the valley at this point. The quarry 

 is known as the ''Blue Stone" quarry and turns out a very good 

 grade of blue stone. The stone is of very uniform grain, but is 

 rather coarse. The surface of the Oolitic stone undei^ the thin 

 overburden of Mitchell limestone is comparatively smooth, and 

 little waste stone has to be stripped off. The stripping consists 

 of about 5 feet of sandy clay and about 3 feet of much weathered 

 Mitchell limestone. The upper 5 feet of the Oolitic stone is 

 waste and the average thickness of the working bed is about 30 

 feet. This is taken out by 4 channel cuts. The upper 2 channel 

 cuts are buff and mixed stone, but the lower beds of the quarry 

 are of a very uniform blue color. There are a few vertical seams, 

 but the beds are well suited for quarrying large blocks. 



The Star Stone Company's mill and quarry, opened in 1895, 

 are located about 100 yards east and south of the Hunter Brothers' 

 quarry. The workings are against the east side of the valley in 

 its northeast corner. Three floors have been worked and a fourth 

 is being stripped at the time this report is written (1914). Thirty 

 feet of workable stone is obtained in four channel cuts. The 

 stone turned out is a fair grade of mixed stone. The quarry face 

 contains more blue than buff stone, but the line of parting 

 between the two is very irregular. The upper beds uncovered 

 by the hydraulic stripping are very uneven, and much waste 

 stone has to be removed before the workable stone is reached. 

 The stripping consists of about 8 feet of sandy clay, and the 

 upper layers of the Oolite, which latter are much weathered. 



There are two or three deserted quarry openings in the valley, 

 the largest being the quarry known as the Johnson quarry. This 

 quarry was opened in 1892 by the Chicago and Bloomington 

 Stone Company. It is located about one-fourth of a mile north- 

 east of the old Hunter quarry. The stone at this point is very 

 similar to that in the Consolidated Stone Company's quarry
