80 FARM GRASSES OF THE UNITED STATES 



according to the census of 1900. In counties having 

 from 500 to 1,500 acres, a small dot was placed ; two 

 small dots were placed in counties having from 1,500 

 to 2,500 acres, and so on. The border of the real 

 Timothy Region is thus seen to traverse central Dela- 

 ware and central Maryland. It includes in the timo- 

 thy region the mountainous parts of Virginia, a small 

 portion of northwestern North Carolina and of north- 

 eastern Tennessee. Southwestern West Virginia is 

 excluded. Thence the line runs irregularly through 

 northern Kentucky, southern Illinois, and southern 

 Missouri. Thence it runs northward, including one 

 tier of counties in southern Kansas and three tiers in 

 the north, and cutting across the southeast corner of 

 Nebraska. It then follows the west line of Iowa, 

 nearly to Minnesota, after which it takes an irregular 

 course across Minnesota and Wisconsin. Timothy 

 does very well in the eastern parts of Kansas, Ne- 

 braska, and the Dakotas, but the enormous quantities 

 of wild hay cut in those States (see Fig. 3) renders 

 timothy comparatively unimportant there. A few 

 large dots, scattered here and there near the border 

 line, and quite generally in the Northern Rocky 

 Mountain and Pacific Coast States, indicate centres in 

 which timothy is more or less important. South and 

 west of this border line timothy is of little impor- 

 tance, with the exceptions noted. It cannot stand the 

 summer climate of the South, nor the arid or semi-arid 

 conditions of the West. North and east of this line it 

 has heretofore been the one great hay grass. Outside 

 of it, it will, for the most part, thrive only under the 

 most favorable conditions. In the Northwest the su-
