the same period. The weight per bushel of the naked varieties is 60 

 pounds, while that of the hulled varieties is 48 pounds, so that the 

 actual difference in yield is less than would appear from these figures. 

 The yield of the Nepal in pounds is about three-fourths that of the 

 White Smyrna variety. 



The average dates of sowing, heading, and ripenmg, and the 

 average height, yield, and weight per bushel of these six varieties for 

 five years (1910, 1911, and 1913 to 1915) are given in Table XXII. 

 These average yields are shown graphically in figure 14.

EXPERIMENTS WITH FLAX. 



Experiments with flax were not started until 1911. Flax is not 

 grown to any great extent in the Judith Basin. The crop is important 

 in the eastern part of the State, although there is not as much flax 

 raised now as there was several years ago. It is usually grown in 

 newly settled districts, as it is considered a good crop to grow on sod 

 land.., 



The experiments at Moccasin have included tests of both seed and 

 fiber fiax. Quite a number of fiber varieties were tested in 1911, but 

 as they were of little value for seed production they were discarded. 



VARIETAL EXPERIMENTS IN FIELD PLATS. 



Nineteen varieties of flax have been grown in the varietal test. 

 Of these, 12 belong to the European seed, 2 to the Smyrna seed, 4 to 

 the European short fiber, and 2 to the European textfle fiber group.
