THE GRASS CROP 7 
usually sown with oats when grown for hay. It also 
includes the cow-peas of the South when cut for hay, 
though these are practically never sown with grain. 
Under ‘‘ Forage Crops’’ are included sorghum, Kafir- 
corn, milo maize, Indian corn, etc., when cut and fed in 
the green state, made into silage, or when grown for the 
fodder alone, as all of these crops except Indian corn 
and Kafir-corn usually are. The two latter, when 
grown for grain, are not included here. 
The crop designated ‘‘ other tame grasses’’ is by 
far the most important of all. It includes timothy, 
timothy and clover, redtop, orchard-grass, brome-grass, 
meadow-fescue, tall meadow oat-grass, etc. There are 
no definite data to indicate in what proportion these 
grasses occur, but common observation and extensive 
correspondence with farmers indicate that the area of 
all others together is decidedly small when compared 
with the area of timothy, or a mixture of timothy and 
clover, and we may fairly refer to the region producing 
this crop as the ‘‘ timothy region.’’ Omitting for the 
present the wild grasses, these hay crops will be con- 
sidered in the order of their importance. 
By reference to the map (Fig. 17), it will be seen 
that the crop designated as ‘‘ other tame grasses’’ oc- 
curs principally north of the Ohio River and east of the 
west line of Missouri and Iowa. Theareaof this crop 
is given as 31,302,000 acres. It therefore constitutes 
74 per cent. of the total area of tame hay. ‘The aver- 
age yield is 1.1 tons per acre, making a total of 35,- 
624,000 tons of hay, consisting almost exclusively of 
timothy, or timothy and clover. The yield per acre 
of this crop is lower than that of any other tame hay
