Fig. 33. — It should be noted that a dot ou this map represents only one-fifth as ^luch 

 acreage as on the maps of corn, wheat, and oats. Barley is a minor crop m the 

 United States compared with these crops, except in southeastern Wisconsin, southeastern 

 and northwestern Minnesota, the eastern portions of the Dakotas. and the valleys or 

 California. In these five States nearly two-thirds of the Nation's barley acreage is 

 found. Minor centers may be noted on the map in northwestern Kansas, southeastern 

 Michigan, and northwestern New' York. These terley districts are characterized by a 

 cool, sunny climate. The crop in California is grown during the winter. Much Dariey
