generally used, the proportion rising to 76 per cent in [llinois. In 
the spring-wheat region there are several reasons for prominence of 
broadcasting. One comes from a prevalent practice of sowing wheat 
on the irregular surface of a cornfield without plowing; another is 
found in the use of the combined cultivator and broadgast seeder, 
which destroys many of the weeds that would otherwise be left 
between the drills. * * * The result of the investigation shows 
that 47 per cent of the winter wheat and 30 of the spring, or 37 of 
both, represent the proportion seeded by the drill. The improvement 
by drilling is made to average 10 per cent. The average shite of 
seed used for seeding winter wheat is 1.35 bushels per acre; 1.24 for 
drilled, 1.44 for the sown. The details are as follows:
