EXPERIMENT MADE BY J. C KTLLEnREW, 

 Newton, Dale Count v. 

 Soil, Sandy Loam ; Subsoil, Bed Clay . 

 In Mr. Killcbrew's experiment for 1891, nothinf^ is gained from 

 the use of acid phosphate, as is shown when plot No. 6 is compared 

 with plot No. 9, while in 1892 it is clearly seen that phoephoric 

 acid is the leading element needed. The increase of plot No. 2 

 over average of unmanured plots 4, 8 and 12, is 25G pounds per 

 acre. Plot No. 6 gives an increase of 288 pounds, and plot No. 9 

 gives 576 pounds increase. The results from plot No. IG are very 

 marked. In 1891 the increase over plot No. 9 is 16 pounds, but in 

 1892 it is 160 pounds per acre. Floats with green cotton seed, and 

 floats with nitrate of soda, give same results in 1891, but in 1892 

 floats with green cotton seed give 514 pounds more than floats with 

 nitrate of soda, but no more than green cotton seed alone, as in plot 

 No. 13. '
