 vania.

 valued at |91,714. 



Pennsylvania produced of mortar colors 2,711 tons, valued at 

 $33,752, as against 9,960 tons, valued at |107,780 for the entire 

 country. 



SLATE AND SHALE 



A considerable quantity of slate and shale are annually ground 

 up for use in pigments and as fillers. In 1910, the individual figures 

 of State production are not available; Pennsylvania's production, 

 however, places the State in the front rank. 



MINERAL WATERS 



From forty-four springs in various counties of the State, Pennsyl- 

 vania produced in 1910, 2,536,337 gallons of mineral water, valued 

 at 1221,685. 



The standing of Pennsylvania is as follows: In the number of 

 springs, third (3rd), quantity sold, fifth (5thj ; in total value, eighth 

 (8th). 



SALT AND BROMINE 



A considerable quantity of both salt and bromine were produced 

 in Allegheny county, Pennsylvania, but unfortunately, both the quan- 

 tity and value are not available for publication. 



LIME

 Union; Ohio ranking second with a production of less than one-half 

 that of Pennsylvania.

 short tons, valued at |13,894,962. This was produced by 1,125 opera-

 714 short tons, valued at |2,440,350.

 |3.99 for the entire country. The highest price per ton was |9.65, 

 the average price of lime in Oregon. 



POTASH SALTS. 



It will be interesting to the farmers of Pennsylvania to know that 

 an investigation has for some time and is still being pursued to 

 learn of any and all sources in the United States from which potash 

 can be derived. It is to be hoped that a successful termination of 

 the investigation will occur and that our country will supply all the 

 demands and that recourse may not be then necessary to import this 

 needful fertilizer, so necessary to the farmer, from foreign lands.
