 or nearly three-fourths, were produced in Germany, Russia, 

 and Austria-Hungary. The development of the beet- 

 sugar industry in the United States is of comparatively recent 

 date. It was not till 1906 that the production of sugar from 

 beets in this country exceeded that from sugar cane. In
