BROOM-CORN EXPERIMENTS AT WOODWARD, OKLAHOMA. 33 
5-year period was 82.5 per cent, which was produced from the normal 
rate. In the Dwarf variety, the average production of good brush 
increased from 79.7 per cent at the thick rate to 84.7 per cent at the 
thin rate. The average from the normal rate was 80.8 per cent.

COMPARATIVE YIELDS IN THE RATE-OF-SEEDING EXPERIMENTS. 
The yield and the quality of the brush are influenced by seasonal 
conditions. No one rate of seeding, therefore, will prove best in all 
years. But as the season can not be foretold the rate that gives the 
highest average yield in a series of years would appear to be the 
most profitable. Table XII shows the annual and the average acre 
yields of both good and poor brush by both the Standard and Dwarf
