before getting on any line of transportation out of it, leaving 2,220,000 

 barrels as the quantity actually marketed or refined. 



Of this quantity, probably 1,600,000 barrels were sent out of the 

 region, either as crude or as refined, to eastern or foreign markets. At 

 Pittsburgh, 278,000 barrels of crude, and 230,500 barrels of refined, were 

 sent east by railroad ; 12,500 barrels of crude, and 20,000 barrels of 

 refined, being sent to western markets. There is a local consumption 

 and distribution other than by railroad of 10,000 to 15,000 barrels. 

 There must have been sent from Pittsburgh and its vicinity about 

 875,000 barrels of crude oil. There was taken northwards for distribu- 

 tion in the Western States about 600,000 barrels. The quantity deli- 

 vered at New York during the year is stated at from 720,000 to 750,000 

 barrels, nearly one half of which was refined. 



The large production, giving an average of about 5,500 barrels net 

 per day, surpassed the demand, and there is now a larger quantity of oil 

 in the United States than at the beginning of last year. 



The following table gives the figures for the distribution of the 

 article and the stock on hand : —

Leaving stock of crude and refined oil in the United States, December 

 31, 1863, equal to about 444,000 barrels refined. 



The greater part of this stock is in the interior of the country, chiefly 

 at Pittsburgh. The stock at the wells is but light. 



The increased shipments to Europe caused there likewise an 

 accumulation of the article during the greater part of the year ; but 

 since the beginning of the winter months, when reasonable prices 

 permitted the article to be more generally introduced, stocks greatly 

 diminished. 



Taking the result of the following table as the basis, the European
