hay $6 a ton, in addition to the expense of harvesting and marketing, then the total value of the manure spread on the land is $2.07 a ton. "Where $1.20 worth of raw phosphate (320 pounds) were added in connection with the manure the average yields were as follows: 61.4 bushels of corn 26.3 bushels of wheat 2.23 tons of hay "And where $2.40 worth of acid phosphate (320 pounds) were used with the same amount and kind of manure the following average yields were secured: 60.4 bushels of corn 26.5 bushels of wheat 2.16 tons of hay "These are the actual yield, and by any method of computation yet proposed, each dollar invested in raw phosphate has paid back much more than has a dollar invested in acid phosphate." "And was the use of the raw phosphate really profitable?" asked Mr. West.
