part of the increase came from the companies manufacturing wall 

 plaster and plaster of paris. 



The combined value of the petroleum and natural gas produced 

 in the State was $2,173,931. The quantity of petroleum made was 

 949,511 barrels. No noteworthy discoveries of new oil pools were 

 reported, and here is little prospect of there being any marked 

 expansion of the present productive fields in the future. The 

 natural gas industry, however, continues to show progress, due to 

 the active development of the Erie county field. At a value of 23 

 cents per 1000 cubic feet, the average reported by the principal 

 producing companies, the total quantity of gas produced was 

 2,639,130,000 cubic feet.
