302 EXPERIMENT STATION RECORD. 



samples taken ou .July 16, 1894, from as many different fields, there is only one excep- 

 tion to the rnle th:it ^vhile the surface 2 ft. of the 3-inch cultivation is more moist 

 than the 1.5-incli cultivation the reverse of this is true of the third and fourth feet, 

 these being dryer. The facts appear to be that while the surface 2 ft. of soil are 

 more moist they are drawing water faster from the third and fourth feet than they 

 could were they dryer." 



Effect of deep and sliallow cultivation on soil temperatures (pp. 283, 

 284). — During 1894 soil temperatures were taken to depths of 3 ft. in all 

 tlie fields under experiment, with wholly concordant results, showing 

 that the soil cultivated li in. deep was warmer than that cultivated 3 in. 

 deep, the mean difference being for the first foot 0.82° F. ; second foot, 

 0.59° V.', third foot, 0.36° F. The difitereuces were less than those 

 recorded the previous season. 



The diurnal changes of temperature at a depth of 1 ft. were also 

 studied by means of 2 self recording thermometers. 



"The mean daily changes during the week ending July 26 were for 

 the lA-inch depth 1.05° F. and for the 3-iuch depth 1.45° F., making a 

 difterence in the diurnal range of 0.2° F." 



Effect of previous manuring on yield of corn, W. C. Latta {Indi- 

 ana ^Sta. Rpt. ls9o,2). 3S). — On laud continuously in corn fresh horse 

 manure was applied to alternate plats in 1893 and 1894 at the rate of 

 50 tons per acre for the 2 years. 



The increased yield attributable to residual efi'ect of manure was 4 

 bu. per acre in 1895, and 123 bu. in the aggregate for 12 years. 



Tests of forage grasses, G. ^McCarthy and F. E. Emery {North
