and no surer varieties will be found than those obtained from the 

 Indians. 



Improved American Varieties: Five varieties including sweet, 

 dent and pop corn were planted in 1912. See Table XLVIII. The 

 heaviest yield was obtained from a plot of Reid's Yellow Dent, a 

 plot of White Dent yielding the next largest amount. 



The 1913 corn test included'thirteen varieties, the highest yield 

 being secured from a plot of Reid's Yellow Dent, the next best 

 yield coming from a plot of King Philip. 



Twenty-five varieties were tested in 1914, the best yield, 3630 

 pounds of ear corn per acre, coming from a plot of White Dent. 



Of the eighteen varieties tested in 1915, the best yield, 1760 

 pounds of ear corn per acre, was obtained from a plot of Reid's 

 Yellow Dent, a plot of Bloody Butcher coming second, with a 

 \ield of 1720 pounds per acre. 



In summarizing the test of improved varieties of American 

 corn, yields for a given variety in any one year are calculated by 

 averaging all of the plots of that variety grown in the year speci- 

 fied. As will be seen in Table XLIX, best results were obtained 

 from Reid's Yellow Dent, while King Philip, Bloody Butcher, 

 Hickory King, and Maul's Yellow Dent were promising. 



Table XLIX shows an especially heavy yield of earn corn for 

 the season of 1913. The distribution of summer rainfall at this 

 time apparently supports the theory that an excess of moisture dur- 

 ing the earlier growing period tends to exaggerate vegetative 

 growth at the expense of grain production. In 1913 the summer 

 rainfall was somewhat delayed- not beginning until after the corn 

 plants had begun to form grain, and, as a result, grain formation 

 was stimulated at the expense of vegetative growth. 



FRUIT 



To determine the practicability of fruit raising by dry-farming, 

 2. small orchard of the following varieties of trees was planted in 

 the spring of 1912: 



Apples: King David 

 Rome Beauty 

 White Winter Pearmain 

 Arkansas Black 

 Gravenstein
