 PRODUCTION AND ADAPTATION 



168. Production. — The world's annual production 

 of rye for the five years 1907-1911 was approximately 

 1500 million bushels, being slightly greater than that of

 and less than one-half that of oats for the same time.

 while in Germany over three times as much rye is pro- 

 duced as wheat. The other countries producing com- 

 paratively large amounts are Austria-Hungary, Australia,
