per day, fresh coal and rock being constantly added to keep the kiln 

 full to the top. This is continued as long as desired, or until repairs are 

 needed. 



The material is next taken to the mill, where it is reduced by stone 

 crushers, especially constructed for this purpose, to such a degree of fineness 

 that it can be fed evenly through a hopper to the millstones where it is pul- 

 verized to the fineness of Hour. It is now hydraulic cement, and ready for 

 use. It is shipped in bulk, or packed in barrels or sacks. 



Although the two layers previously described comprise all of the water- 

 lime rock of commercial value in this county, the quantity of raw material in 

 sight and convenient of access is practically unlimited. One cord of stone 

 makes 100 bushels of cement, and the output can easily be increased to meet 

 all demands.
