river. It would then run irregularly across the 

 states of Missouri and Kansas to about the latitude 

 of Denver in Colorado. From Denver it would 

 probably rise to the latitude of Salt Lake City, or even 

 further northward in the lower valleys, and it would 

 again dip southward, reaching the sea somewhere 

 about San Francisco. North of this line it is pretty 

 certain that corn could be grown more profitably at 

 the present time, for the combined uses of the prod- 

 uct of the grain, the fodder and the pasture. But 

 for pasture only, some of them are likely to prove 

 more valuable than corn, although it is questionable 

 if any of them will show a higher relative value than 

 the saccharine sorghums in providing pasture north 

 of the said line. Saccharine sorghums germinate 

 more quickly, at least in some of their varieties, and 

 are better able to endure lower temperature. But as 

 the non-saccharine sorghums become better acclima- 

 tized, more may be expected from them. The growth 

 of these, however, is not likely ever to prove profit- 

 able in any considerable areas of Canada, since in 

 that country the mean summer temperatures are low. 

 And the expectation is natural that the non- 

 saccharine sorghums will not grow equally well in all 

 parts of the south. Future experimentation with 

 them will doubtless show special adaptation to cer- 

 tain peculiarities of soil and climate. Already are 

 they being grown more in certain centers than in 

 others. Kaffir corn has given excellent results in the 

 dry areas of Kansas and Oklahoma. Milo maize has 

 grown excellently well in certain of the Atlantic 

 states, notably Georgia, and teosinte is giving 

 evidence that it is going to be a child of the far south- 

 ward portion of this country.
