The total volume of drainage was 5,651,776 cubic feet, or 51.8 per 

 cent of the water added to the tract. This 51.8 per cent drainage 

 water carried 3,648 tons of salts over the outlet weir. The remainder 

 of the salts removed from the tract have passed into the deeper subsoil 

 and been carried away by the natural subdrainage. 



The results so far obtained indicate the ultimate complete reclama- 

 tion of the land. The single season's operations produced marked 

 improvement in the land, not only in the alkali content, as shown by 

 the soil tests made, or as shown by the salts in the drainage, but also 

 as shown in the improved tilth of the soil and the favorable changes 

 that have taken place in its physical properties. 



The indications are that the greater part of the tract is at present 

 sufficiently sweetened to allow the growing of shallow-rooted crops. 

 It is the intention to continue the work until reclamation is complete, 

 and the data pertaining to the process of flooding and drainage will be 

 supplemented by practical crop tests during the season of 1904.
