generally used, the proportion rising to 76 per cent in Illinois. 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 broadcast 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 quantity 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 :
