cotton-seed meal, 45 pounds of acid phosphate, and 2 pounds of 

 potassium chlorid, in 100 pounds) was applied at the rate of 200, 

 400, and 600 pounds per acre, and the respective yields of corn 

 were 35.8, 37.0, and 38.4 bushels per acre, from which the conclu- 

 sion is drawn that " the results only confirm conclusions repeatedly

In this connection the following rainfall records are of interest:

The yearly records for 1900 and 1904 are the extremes for the 

 seventeen years. 



In Table 102 are recorded the results of a series of fertilizer ex- 

 periments with cotton, as reported in Georgia Bulletin 63. 



For the 1904 corn crop fertilizers were applied uniformly to all 

 plots (except No. n) as follows, in pounds per acre: 



In 1906 cotton was grown on at least part of the same land as in 

 1903, with the plan of experiment and results reported in Table 

 103. It is not clear whether these results may have been influenced
