where it is finding favor on account of its high yields on rich valley 
soils or on irrigated lands. 
OTHER VARIETIES OF WHITE WHEAT 
Of the other commercial varieties reported in both 1919 and 1924, 
Bunyip, Big Club, Rink, Greeson, Sevier, BlueehafT (club), and 
Regenerated Defiance increased in relative acreage, whereas the 
acreage of the remaining varieties was either maintained or reduced. 
Most of the less important white wheats should be replaced by better 
varieties, and this evidently is being done. New varieties, not reported 
in 1919, which are becoming important are Federation, Hard Feder- 
ation, Quality, and Honor. The acreage of Federation, Bunyip, 
Hard Federation, and Honor probably should show still further 
increase in the future. 
SUMMARY OF CLASSES AND VARIETIES 
The distribution of the classes and varieties of wheat in the United 
States is summarized according to acreage and percentages in the 
States, which are arranged in geographical divisions. 
CLASSES 
The distribution of the classes of wheat, by States arranged geo- 
graphically, is shown in Table 9. 
The hard red spring class of wheat is grown in all but the South 
Atlantic division, but principally in the North-Central States. It is 
the leading class of wheat in Maine, New Hampshire, Vermont, 
Wisconsin, Minnesota, North Dakota, South Dakota, Montana, 
and Wyoming. Thirty States report the growing of hard red spring 
wheat. 
Durum wheat is grown in the same general divisions and in most 
of the States where hard red spring wheat is grown. It is not a 
leading class of wheat in any State, but it is most widely grown in 
North Dakota. In South Dakota, however, it occupies a greater 
percentage of the total wheat acreage than in any other State. Min- 
nesota and Montana rank third and fourth, respectively, in the 
acreage of durum. Nebraska, Colorado, and Wyoming also grow
