SUB-IRRIGATION AND SUBSOILING. 293 



plow would run with the near horse close to the last 

 mark. After this back furrow laud became about thirty 

 feet wide I split the marks going one way, and came 

 back five feet away as before, thus always turning one 

 way; and as I leaned the plow only a little I plowed 

 around the ends, which in fact were the best plowed. 

 This second plowing was done to the hardpan but not 

 in it. The soil was real moist for six inches down, when 

 from there to the hardpan it was as dry as blotting 

 paper, and had probably not been wet for two years or 

 more. Now this earth is at least six to eight inches 

 higher than before, and will take in all the rain it can 

 hold, and the lower soil in drying out again will of 

 necessity supply the surface with moisture, as the gumbo 

 below it is waterproof."
