Fig. 83. — The number of registered pure-bred beef cattle i.s more concentrated geo- 

 graphically than that of all beef cattle, Iowa alone has one-seventh of the entire num- 

 ber in the United States. Fiv.e per cent of the beef cattle in Iowa are registered. The 

 prairie and plains portion of the United States (see "tall grass" and "short grass" 

 of Fig. 7) has nearly four-fifths of the pure-bred beef cattle in the country. About two- 

 flfths of the registered beef cattle are Shorthorns — nearly one-half if Polled Durham 

 be included — and nearly two-fifths more are Herefords. Aberdeen-Angus constitute about 

 one-tenth of the total number. Iowa leads the States by a wide margin in numter of 

 Shorthorns and Aberdeen-Angus, while Texas leads in number of Herefords. 



Fig. 84. — Sixty per cent of the registered pure-bred dairy cattle are concentrated in 

 the Hay and Pasture Region. About 5 per cent of the dairy cattle in this region are 

 registered. New York has one-sixth of the registered dairy cattle in the United States, 

 and WiscoflSin has one-eighth. Much smaller numbers mav be noted in the valleys of 

 California and of western Oregon and Washington. About 58 per cent of the registered 

 dairy cattle in the United States are Hoistein-Frlesians, 25 per cent are .Terseys, 9 per 

 cent are (iuernst>ys, 3 per cent are Avrshires, and 1 per cent Brown Swiss, the re- 

 mainder being unspecified.
