BROOM-CORN EXPERIMENTS AT WOODWARD, OKLAHOMA. 28 
twisted brush. In the latter year growth was retarded, so that a 
number of short, spiky heads developed which were of poor quality 
and averaged only 13.2 inches in length. The lowest average per- 
centage of good brush in the 5-year period was made in 1916. In 
that year the length of good brush averaged 18.8 inches, but it 
amounted to only 80.9 per cent of the total crop. The same year 
the average length of the poor brush was only 14.7 inches, or 4 inches 
less than the good brush. This was due to extremely dry conditions 
in the latter half of the heading period.
