can be served by a second or other delivery at a cost not in excess of $8 per 

 acre for the land to be served and benefited through them. (4) When lying 

 in a depression, if it can be drained at a cost not exceeding $8 per acre and is 

 .suitable arable land which would be benefited by irrigation. 



"(5) The prices to be made use of in estimating the cost of embankments, 

 flumes, or other structures shall be, unless otherwise ordered by the Minister 

 of the Interior [as follows] : Earth fill or excavation, 12 cts. per cubic yard; 

 lumber in place on any structure, $40 per 1,000 ft. board measure; and rock 

 riprap, 50 cts. per superficial yard. 



"(6) In all unusual or exceptional cases, which are not covered by the 

 preceding paragraphs, the classification will be made by officers of the depart- 

 ment, imder the direction of the minister of the interior, in a fair and reason- 

 able manner, and will be based on the beneficial use of water."

Reclamation of the Worden tract, D. Hansen {U. S. Dept. Agr., Bur. Plant 

 Indus., Work Huntley Expt. Farm, 1915, pp. 22-2^, fig. i).— Drainage of a 

 heavy alkali soil in which the water table stood at a depth of only 0.77 ft. 

 lovv-ered the ground-water table to a depth of 6 ft. 



The experiment farm drainage system, F. B. Headley {U. S. Dept. Agr., 

 Bur. Plant Indus., Work Truckce-Carsoii Expt. Farm, 1915, pp. 12-14). — Esti- 

 mates of the total amounts of salts removed in the drainage water in the 

 experimental drain on the project sliow that the largest amount of salt is 

 removed during the irrigation season. 



"A total of 214 tons of alkali has been removed by this drainage system in 

 three years, approximately 8.5 tons for each acre of the area drained. The 

 amount of salt in the upper 3 ft. of this portion of the farm amounts to ap- 

 proximately 9 tons per acre, or about the same amount as has been removed in 

 three years by the drainage system. The soil of the area served by the 

 drainage system does not show any appreciable reduction of its salt content 

 in the upper 3 ft. It Avould appear, therefore, that the tile-drainage system 

 draws alkali water either from sources deeper than the surface 3 ft. of soil or 

 from an area much larger than the actual extent of the system. Beneficial 

 results, as indicated by the improvement of crops, do not seem to have been 

 obtained as yet from the installation of this system of drainage, although it
