In the variety tests three rows on either side of each plot were harvested 
separately, bound and tagged. They are referred to as outside border 
middle border, and inside border rows, respectively. In the rates o 
seeding tests, two border rows were removed from either side o eac i 
plot in turn, bound and tagged. They are referred to as outside and in¬ 
side border rows. In both tests the rows remaining after the various 
border rows were removed are referred to as central rows. I liey were 
harvested with the binder. At thrashing time each row or rows, in the 
case of the central areas, were thrashed with a small machine, and the 
grain was weighed. 
The sizes of the areas from which yield determinations were made 
are given in Table I.

In order to secure the yields of the various plots with no border row 
removed, one removed, two removed, and (for the variety test) three 
removed, the weights of all portions of each plot were added together 
to secure the yields with no border rows removed. Likewise for the 
variety test the weights of the central rows and the two middle border 
rows were added to secure the yields with the outside border rows only 
removed, and for the rate test the inside border rows were added. In 
the variety tests the weights of the central rows and those of the inside 
border rows were combined to secure the yields of the plots with two 
border rows removed. The yields for the variety plots with three 
border rows removed and the rates of seeding plots with two border 
rows remoyed were computed from the weights of the grain from the 
central rows. The total weight of grain from the central lows was 
divided by the number of rows in order to secure the average yield for 
these rows. All computations have been checked.
