Mance: Quarry Industry of Southern Indiana 79 



laid down at Bloomington is 55 cents with an additional 5 cents 

 per ton for switching to the various quarries when such switching 

 necessitates setting the cars on private switches. The subject of 

 coal composition and heating value is narrowed by the few coals 

 available, but a few analyses of coals will be of interest in this 

 connection. The U.S. government maintains, under the super- 

 vision of the Bureau of Mines, a coal-testing plant at Pittsburgh, 

 Pa., where any coal submitted in carload lots by the mine owners 

 will be tested free of cost. A number of the local mine owners 

 have availed themselves of this offer, and the literature concern- 

 ing these tests is available for free distribution by the Bureau of 

 Mines at Washington, D.C.
