BITUMINOUS COAL 



The tonnage mined from the Bituminous coal fields of Pennsyl- 

 vania in the same year was 150,521,526 short tons or more than double 

 that of its nearest competing state. West Virginia. The spot value 

 of this tonnage was $153,029,510. The spot value of Pennsylvania's 

 total tonnage for 1910 was $313,304,812, while that of the United 

 States was $029,557,021. Pennsylvania produced 40.8 per cent, of 

 all the coal mined in the United States in 1910. The tonnage of the 

 entire country was 501,596,378 tons of which amount Pennsylvania 

 produced 235,006,762 short tons or more than three and a half times 

 as much as any other state. In fact, the production of coal in Penn- 

 sylvania in 1910 exceeded the combined tonnage of West Virginia, 

 Illinois, Ohio, Indiana, Alabama, Kentucky, Colorado, Iowa, Wyom- 

 ing, Tennessee, Virginia and Missouri by ove-r 50.000 tons. To mine, 

 prepare and ship this tonnage of Pennsylvania required an army 

 of 344,900 men and boys. 



It is more than of passing interest to know that the United States 

 mines nearly 40 per cent, of the annual output of the entire world. 

 Pennsylvania and West Virginia produced more coal in 1910 than 

 Oreat Britain; Penn.sylvania's production was but 10,036,538 tons 

 less than that of Germany. 



COKE 



Pennsylvania produced in 1910 more than 60 per cent, of the en- 

 tire coke output of the United States, its production being 26,315,- 

 607 short tons, valued at $55,254,599. The quantity of coke manu- 

 factured in the United States was 41.708,810 short tons, valued at 

 $99,742,701; more than 50 per cent, of all the coke ovens in the 

 country are in Pennsylvania, 



PETROLEUM 



Although Pennsylvania produced the first petroleum on a com- 

 mercial scale from a well at Titusville in 1859. and long remained the 

 leading oil producing state, it has dropped from -the first to the 

 seventh in rank of oil producing states. 



The total production of petroleum in the United States in 1910 

 was 209.556.048 barrels, valued at $127.896..328. Of this amount. 

 Pennsylvania produced 8.794.662 barrels, valued at $11,908,914. Al- 

 though seventh in rank as a producer, Pennsylvania stands fifth as 

 to the value of its product. 



Up to 1876. Penn.sylvania and New York were the only states pro- 

 ducinsr petroleum on a commercial scale. In that year, Ohio, We-st 

 Virginia and California took their places as producers. These were 

 followed by Kentuckv and Tennessee in 1883, Colorado in 1887. In- 

 diana and Illinois, Kansas, Texas and Missouri, Oklahoma in 1891, 

 Wyoming in 1894, Louisiana in 1902. 



California C34.84 per cent.). Oklahoma (24.83 per cent.1. Illinois 

 C 15.82 per cent.^l in 1910 produced over 75 per cent, of the entire 

 petroleum output of the T"'nited States. In 1859, the total production 

 of petroleum in the United States was but two thousand (2,000) 

 barrels.
