figured the increase at the actual price I received for my own crops that 

 year. The following table gives this record: 



This leaves a nice profit, but the most important fact is that most of 

 the phosphate is still in the ground waiting for the clovers to come along 

 and release it. 



If the entire volume of grain produced since 1915 is taken it will be 

 found that only about 60 tons of the 1252 tons of raw rock phosphate has 

 been used. 



Q. Mr. Meis, in figuring the cost are you figuring labor? 



Mr. MEIS: My labor on that has not been very big, because I have 

 been able to get that mostly in the fall of the year and I have not had 

 very far to haul, from two to four miles. I haven't figured any labor, just 

 the actual cost of the phosphate. 



Q. Have you applied that on 400 acres? 



Mr. MEIS: That is on 400 acres. I had 320 to start with. 



Q. Mr. Meis, you have got about $9,000 profit there. How much phos- 

 phorus have you got in your soil? You put on three tons. You have got 

 phosphorus to run you for a good while, haven't you? 



Mr. MEIS: A good many years. I have not really taken this up with 

 anybody. Mr. Mann can probably tell you more about it. I figure that this
