The writer calculates that the United States might produce each year : 

 a) 268 000 lbs of fatty cherry oil, of a value approximate to that of peach 

 oil, which has ranged from 22 cents pei lb in 1913 to 45 cents in 1915 ; 

 h) 6 000 lbs of volatile oil of a value close to that of the oil of bitter almonds, 

 which in January 1916 was quoted at 9.25 to ii dollars per pound ; c) about 

 300 tons of distilled oil cake flottr.
