June, 1921] Steel Molding Sand in Ohio 263 



Newman Silica Sand Company. This plant is located on 

 the Baltimore and Ohio and Pennsylvania railroads, about one- 

 half mile above Pauls, Stark County. The rock is broken in 

 a jaw crusher and then passed through two sets of rolls, after 

 which it is washed and some of it screened. It is then ready 

 for shipment. The sand is used for steel molding and furnace 

 bottoms. It was formerly used in glass manufacture. The 

 capacity of the plant is about 100 tons per day. 



A ledge of 30 feet of sandstone is worked, above which is 

 4 to 6 feet of stripping. The sandstone is coarse, has a buff 

 color and parts are impregnated with iron. A dark shale lies 

 below the sandstone and still lower the Massillon or No. 1 coal 

 is reported. The rock is loaded by hand and hauled to the mill 

 by gravity. 



For many years the Lower Massillon sandstone was worked 

 at Pauls for foundry facings, furnace bottoms, and to a small 

 extent for glass, but the plant was destroyed by fire a few years 

 ago and it has not been rebuilt. 



THE DUNDEE SANDSTONE. 



The Dundee sandstone lies near the middle of the Pottsville 

 formation. It cannot be said to be steady or persistent, 

 however, for its place is frequently occupied by shales, but it is 

 well developed locally and in a few places is of value. 



The one locality where the Dundee sandstone is worked 

 in the large way is the valley of Sugar Creek in the northwest 

 corner of Tuscarawas County. The stream has there cut a 

 deep trench in the sandstone and has thus made it readily 

 available. 



The plant at Barrs Mills, operated by the Massillon Sand 

 Stone Company, is the best equipped and the largest 

 producer in the valley. The sandstone worked averages about 

 50 feet in thickness and has a maximum of about 67 feet. 

 Most of the rock has a buff color, but the lower part is in places 

 light gray. It is coarse grained, but without pebbles. 



The rock is transported to the mill by horse power and 

 elevated by cable. It is broken in a gyratory crusher and 

 reduced to sand in a disintegrator. Most of the sand is dried 

 and screened, the coarser material then passing through a set 

 of rolls and being re-screened. Dust is blown from the sand
