In comparing the various varieties with Lee, none was its equal. 
(Fig. 7.) The nearest approach to the yield of Lee was made by 
Custis, a strain of similar origin. Lee has been grown for only four 
years, so that further trial may show some variation from this supe- 
riority, but from present data Lee is more promising than any other 
variety so far grown at Arlington Farm. Lee apparently possesses 
sufficient hardiness to resist to a high degree even the most rigorous 
winter conditions usually experienced at Arlington, varieties with 
less hardiness failing almost completely to survive. The variety is 
considerably earlier than Winter Turf, and its kernel characters are 
of as high a degree of excellence as are possessed by any winter oat. 
Lee is the most promising new variety now available for fall seeding

Fic. 7—Average acre yields of leading strains of fall-sown oats in each of seven varietal groups 
grown in field plots at the Arlington Experiment Farm during the five-year period from 1921 
to 1925, inclusive 
in the northern part of the fall-sown oat section, embracing Mary- 
land, Virginia, North Carolina, and Tennessee, and possibly Arkansas 
and southern Kentucky. 
NURSERY EXPERIMENTS 
In addition to the varietal experiments in field plots, numerous 
varieties and strains of fall-sown oats have been grown in nursery 
experiments at the Arlington Experiment Farm for the determination 
of their adaptation and relative yield. The first nursery was sown in 
the fall of 1907. Since that date nursery plantings have been made 
every year except in the fall of 1912. Owing to severe winterkilling 
followed by a cold dry spring and an unusually heavy growth of weeds, 
the nursery of 1920 was abandoned. In a few other years many of 
the varieties and strains grown in nursery rows were badly injured or 
completely destroyed by winterkilling. The most unfavorable years 
for nursery plantings were 1915, 1916, 1918, and 1920. 
In later years many hybrid selections have been included in the 
nursery experiments. Older strains which could not compete with 
the new high-yielding sorts were discontinued. Altogether, hundreds
