An inspection of Table No. 8 reveals several points of interest. !Most 

 noticeable is the regularity with v/hich the limed areas outyield the not 

 limed areas. In the case of the first two cuttings which include the weeds 

 and clover as well as the alfalfa the increase is 56 per cent. In the third 

 cutting which is nearly clear alfalfa it is 85 per cent. At the first and 

 second cuttings all the plats that had received stable manure (742, 745 

 and 748) produced markedly heavier yields than the others, but at the 

 third cutting only 745, which also received a dressing of inoculated soil, 

 maintained its superiority in any considerable degree. 



It will be remembered that these three plats were quite thoroughly 

 seeded to clover by the manure that was applied to them, so that the hay 

 that was secured from them at the first and second cuttings was chiefly 

 clover with some alfalfa and few weeds. It is of interest to observe that 

 the average yield for the season of the limed ends of these plats was 

 9.557 pounds of hay per acre while the average yield of the unlimed ends 

 was 6,940 pounds, a difiference of 2,617 pounds.
