color develops as the seed matures, and at maturity 
is very nearly a brick-red. The kafirs should not 
be confounded with their sisters—Jerusalem corn, 
milo maize or rice-corn. 
All the varieties of the non-saccharine sorghums 
that will mature in Kansas have been tested side 
by side. For the extreme northwestern counties of 
Kansas, observation shows that kafir corn is not 
so well adapted as Jerusalem corn or rice-corn. 
The altitude being high, the short seasons and 
cool nights seem to affect the kafir corns so that 
they often will not mature seed. Although they 
always make fodder, and sometimes a good crop 
of seed, they are not so reliable as the others. The 
White kafir corn with some is the favorite for fod- 
der, and all varieties have their admirers, but at 
the Kansas Station all have been abandoned for 
the Black-hulled White. It has proved the heaviest 
yielder in both grain and fodder, and if there 1s 
any difference between it and the Red for resisting 
dry weather, it is in favor of the Black-hulled 
White. There is a greater difference between the 
Red and the White in these respects than between 
the Red and the Black-hulled White. 
For the first seven years the Red was grown. 
The Black-hulled White was then tested, and from 
1896 to 1898 the two varieties were grown side by 
side, the Red giving an average yearly yield of 
thirty-seven bushels per acre, and the Black-hulled
