Areas of land of different grades of alkali, September, 190-2, and October, 1903. 



The above table shows clearly the increase in the acreage of soils 

 containing a low percentage of alkali; the columns headed Septem- 

 ber, 1902, showing the original condition of the tract, and those 

 headed October showing the condition at the time of the last exami- 

 nation. 



The following table shows the volume of water added to the tract 

 from September, 1902, until October, 1903. The table shows also the 

 volume of drainage over the outlet weir, and the salts (alkali) removed 

 from the tract in the drainage water. The results are obtained from 

 continuous measurements and daily collections of water samples for 

 the entire period.
