Hyde Park Experiment. 

 This covered two separate holdings, totaling about 31.5 acres in an 

 affected belt of 2,000 acres, between Hyde Park and Logan, on Avhich 

 satisfactory yields had been obtained for twenty years prior to damage 

 by seepage. The soil was black loam, underlaid with yellow clay, both 

 of an open nature. First cereals and root crops gave way on account 

 of seepage to hay grasses, the latter in turn being replaced by water 

 grasses. Lines of 8-inch and 6-inch tile were laid 4 to 4.7 feet deep 

 along the upper edge of the experimental tract to intercept the seepage 

 from the higher lands adjoining, and a line of 5-inch tile was placed 4 

 feet deep lower down to care for the seepage that passed the upper line. 

 Since drainage, yields of 50 bushels of wheat, 100 bushels of oats, and 

 18 tons of sugar beets per acre have been taken from the reclaimed land. 

 The average cost per acre for drainage was il'15.60. 



Garland Experiment. 



The area treated here was 60 acres, the soil being clay loam, iinder- 

 lain by separate strata of sand and clay and pockets of sand, and the 

 tract itself being part of a flat depression separated from Bear River 

 Canal by a stretch of sandy lands. The source of excess water was 

 seepage from irrigation and the canal. Trouble began with a season of 

 subirrigation, when the crops were record breakers. Then several 

 acres became drowned out. Eleven farmers joined the Department of 

 Agriculture in the drainage experiment. Both intercepting and outlet 

 drains were used. Five-inch and 6-ineh tile placed 4 feet deep led to 

 8-inch and 10-inch main outlets. The resulting improvement in this 

 tract after drainage was very marked, not a trace of alkali showing. 

 The average cost per acre was $16.87. Since this experiment was con- 

 cluded a drain-tile factory has been built by neighboring farmers, 

 because the tile the experiment proved were necessary could not be 

 obtained Mdthin a convenient shipping distance. In addition, hand 

 labor has been displaced in some cases by steam trenching machines 

 suitable to the soil present and which excavate the trench to the full 

 required depth at one passage. 



Richfield Experiment. 

 This covered 80 acres in central Utah, the tract having a gentle slope 

 of about 1 foot in 200. The source of seepage water was lateral perco- 

 lation through a sand substratum from higher lands. Two parallel 

 lines of 5-inch and 6-inch tile were laid 600 feet apart across the slope, 

 with a few laterals of 4-inch tile to tap particular spots. The average 

 depth was 5 feet. An open-trench outlet, first proposed to reduce cost, 

 was replaced by a 10-inch pipe drain. Only the very highest portion of 

 the 80-acre field was producing crops when the experiment w^as under- 

 taken, the balance being covered with salt gra.ss. After the ^^•ork was 

 completed a great deal of water was discharged, apparently from every 

 part of the system, damp spots becoming dry and the spread of alkali 

 stopped. The writer has not at hand the results of this experiment to 

 date, but conditions were reported so gratifying that other projects
