The average height of Dwarf milo in all 90 plats in all nine years 

 was 3 feet, compared, with an average of 4 feet for milo. There was 

 an enormous variation in average height from year to year. For 

 instance, in 1916 the average height was only 2.3 feet, and in 1912 

 but 2.6 feet. In 1915, however, under the influence of abundant 

 rainfall, it rose to 4.5 feet, and in 1911 to 4.8 feet. The average 

 height of 1.7 feet, recorded in 1913, included many stalks which bore 

 no heads and therefore had not attained full height. 



The most important character of Dwarf milo is its outstanding 

 ability to produce good yields, as shown in Tables IX and XVIII . 

 The average acre yield from aU the' 90 plats grown in the nine years 

 has been 26.2 bushels. Under the same conditions, the average acre 

 yield from 107 plats of milo was 22.7 bushels. The lowest average 

 yield recorded, except the complete failure of 1913, is 8.6 bushels, in 

 1916. The highest is 68.4 bushels, in 1915. In the same years milo 

 yielded 7 and 61.4 bushels, respectively. The yields of this variety 

 obtained during the nine years of the experiment may be classified 

 as follows: One failure, two poor, three fair, two good, and one 

 superexceUent.

 Arriarillo Cereal Field Station during periods of varying length in the nine years from 

 1908 to 1916, inclusive.

The 9-year average acre yields of two lots grown during that 

 period are 27,1 and 26.4 bushels, respectively. The yield of the best 

 one is 4.2 bushels more than the yield of the best milo in the same
