 snow, which prevents the freezing out of the grains. On 

 ground that has been newly cleared and on rocky lands the 

 broadcast seeder can be used to advantage.

grain binder is most generally used for this purpose. This 

 machine cuts and binds the grain, and if provided with 

 bundle carrier attachment, drops the sheaves at such inter- 

 vals as the operator desires. In some parts of Canada and 

 in the Western States headers and combined harvesters and 

 threshers are used for harvesting the crop. These ma- 

 chines can be so gauged as merely to cut the heads off the
