 and contains a relatively small amount of gas and sul- 

 phur. The oil is steamed and then run into tank cars 

 in which it is transported to the oil refineries at Wood 

 River, The production at the present time is about three 

 tank cars per day, and the selling price of the oil is $1.75 

 per barrel.
