 introduction of the silo, the corn binder is used more than

Results of an investigation of corn harvesting methods * show 

 that the average acreage cut per day with a binder was 7.73 

 acres. The average life of the corn harvester was 8.17 years, 

 cutting on an average a total of 668.77 acres. The amount 

 of twine used* per acre was 2.44 pounds, and one man was 

 able to shock the corn on 3.31 acres in one day. From this
