CHAPTER XXXI. 



PRACTICAL RESULTS. 



What has actually been done to demonstrate that 

 scientific soil culture is practical and that good results 

 follow? 



The question is a proper one. The careful reader of

 tered all through it is given many illustrations of what has 

 been done, and many reports are made of specific results 

 attained under the system. But at the risk of doing that 

 which is needless, we desire here to present just a few facts 

 showing some of the things done, so that the inquirer 

 may have them all in one place to better consider them. 



This work has been done by conducting experiments 

 at a number of places, which a r 3 mentioned in the Manual 

 but we will here confine our record to a few where the most 

 careful work was done. 



First, was the accomplishment at the Pomeroy model 

 farm at Hill City, Kansas, far out toward the Colorado line. 

 This is a locality which has been regarded by many as about 

 as unfavorable as it was possible to find. The author of 

 the Manual conducted for Hon. James P. Pomeroy a model 

 farm, of Colorado Springs, and a great deal of what has 

 been learned came out of that farm. It was started in 

 1900. As illustrating results, it can be said that one field 

 that had been farmed for fourteen years, and never but one 

 crop cut in that time, was summer tilled in 1900, and 

 yielded 42 J bushels of wheat in 1901; was summer tilled
