1 Crop destroyed by hail in 1912. 
The average annual yields of the several crops at Dickinson. Het- 
tinger, and Williston are given in Tables 3, 4, and 5. The yields of 
flax are from a single plat on bromegrass sod at each station. 
Alfalfa is sown without a nurse crop and seldom produces a crop 
of hay the first year. The yields given are the averages of the 
second and third years. Bromegrass is seeded with wheat, and 
no crop of bromegrass hay is obtained the first year. The yields 
given for Dickinson and Hettinger are the averages of the hay crop 
in the second and third years. The yields in the second and third 
years at Williston are shown separately. At that station the yields 
beginning with those in 1915 are from slender wheatgrass. While 
the yields of alfalfa and bromegrass are from the second and third 
years of those crops in the rotations in which they occur, they are 
not always from second and third year sod, because a stand is not 
always obtained the first year.
