The yield and percentage of good brush vary with the season. 
However, a low yield of brush does not necessarily mean a small 
percentage of good quality. In 1918 the yield of good brush was at 
the rate of 283 pounds to the acre, which was 91.1 per cent of the 
total crop. In 1915 the yield of good brush was 600 pounds per acre, 
which was only 79.4 per cent of the total yield. The acre yield of 
good brush ranged from 283 pounds in 1918 to 600 pounds in 1915, 
with an average yield of 392 pounds in the 5-year period, which is 
an average of 88.5 per cent of the total brush produced in that period. 
The annual and the average yields are shown in Table VIII, where 
it will be noted that this variety ranked second in the 2-year average 
and tied with one Dwarf strain for first place in the 5-year average. 
In percentage of good brush it ranks first. This is shown graphically 
in figure 7.

DWARF BROOM CORNS. 
Dwarf broom corn came into prominence during the early nineties. 
owing to its adaptation to dry-land conditions. Since then the 
center of production of the broom-corn crop has moved from Illinois 
westward into Oklahoma. Most ofthe crop grown in Oklahoma and 
adjacent States is of the Dwarf variety except in the Lindsay dis- 
trict of Oklahoma, which includes the Washita bottom lands in 
Garvin, Grady, and McClain counties. As in the case of the Stand- 
ard variety, many names are applied to the Dwarf broom corn. 
Some of the most common of these are California Golden Dwarf, 
Dwarf, Dwarf Evergreen, Evergreen Dwarf, Japanese Dwarf, and
