divided into two series of 15 i)lats each. "Series A liad ."i ]>]ats culti 

 rated twice a we«*k, 5 j)lats once a week, and the leniaiiiinjjj ."» once in 

 2 weeks. The three 5-plat groups in series B were cultivated, respec- 

 tively, two, four, and six times during the season. The implement 

 used was the Daisy si)ring tooth cultivator." The average yields in 

 bushels per acre were as follows: Twice a week, GG.(i3; once a week, 

 09.45; once in 2 weeks, 72.97; twice during the season, <>S.(>2: four 

 times during the season, 70.0(»; six times during the season, 70. OS. *>The 

 highest yields attained in both series, viz, 72.97 bushels pel- acie when 

 cultivated once in 2 weeks, and 7(i.0G bushels per acre when <'ulti- 

 vated four times during the season, is the result of what is luactically 

 the same amount of cultivalion. • • * If this experiment, then. 

 prov<!S anything, it is that in a wet season like the last, and on s«m1 of 

 the character here employed, it is possible to give corn too ntuch as 

 well as too little cultuie."
