selection from a field of Red Rustproof oats in Navarro County, 
Tex. This is a distinct new variety, with a beautiful purple waxy 
bloom at maturity, but it is not promising as a winter oat. It is 
highly resistant to or immune from the smuts of oats and may be of 
value for plant-breeding purposes. 
The Lee and Custis strains, selected from the hybrid between 
Winter Turf and Aurora, have given good nursery yields, although not 
so promising as those in the field-plot experiments. As previously 
noted from plot experimental results, the Lee is especially promising 
for sowing in the northern transitional zone of the fall-sown oat belt. 
The Aurora-Winter Turf strains, including Lee and Custis, as a group 
show high yielding ability, in addition to excellent kernel characters. 
Of the other hybrids which have been grown in the nursery, none 
have been tested long enough to warrant any recommendation. The 
value of most of these strains remains to be determined. However, 
none seems so promising as those from the cross between Winter Turf 
and Aurora. | 
Reverting to the better yields from certain of the more tender 
varieties in nursery experiments than when grown in plots, several 
factors operating alone or in combination may be responsible for this 
result. The nursery rows at Arlington are sown in a decided furrow. 
The furrow undoubtedly affords the young plants considerable pro- 
tection against cold winds and heaving. No such furrow is formed 
on the plots where the seed is sown with a disk drill. The nursery 
rows are sown 12 inches apart, whereas the distance between drills in 
the plots is 8 inches. Approximately equal quantities of seed per 
unit of area are used in the two cases. The greater resultant crowding 
of the plants in the nursery rows may give some additional protection 
against injury by cold. Nursery rows run north and south, whereas 
the plots are drilled from east to west. Prevailing cold winds blow 
from the northwest, and it is possible that the nursery rows running 
north and south are a little better protected than the plot rows run- 
ning east and west.
