4 BULLETIN 1498, U. S. DEPARTMENT OF AGRICULTURE 
The reported acreages of the durum and club varieties are not 
complete because many of the correspondents listed the varieties 
simply as " durum" or "club." A large acreage is shown, therefore, 
under "durum (varieties not reported)" and "club (varieties not 
reported)." 
The acreages of the varieties in 1919 are listed in even hundreds 
of acres, but the exact computed acreages are shown for 1924. 
Varieties which were reported and those of which there were less than 
100 acres in a State in 1919 are included in the lists, but no acreage 
is given. 
The increases or decreases of varieties in acreage shown in 1924, 
as compared with 1919, are not the actual percentages of change in 
acreage but simply the difference between the percentages of the 
total wheat area that the varieties occupied in 1919 and 1924. The 
figures thus show where the variety was relatively of more or less 
importance in 1924 than in 1919 and also the amount of the difference. 
The varietal maps show the distribution of the more important 
varieties, the acreage per county being used as a basis. The scale 
of dots on the varietal maps is on a basis of one dot per thousand 
acres or less per county. A dot thus appears in each county in which 
a variety was reported, even though less than 500 acres were reported, 
because of the desire to show the complete distribution of a given 
variety. 
ESTIMATED ACREAGE OF VARIETIES BY STATES 
The estimated acreages, the percentage of the total wheat acreage 
occupied by each variety of wheat in 1919 and 1924, and the increase 
or decrease in the percentage of the acreage during the 5-year period 
are shown by States in Table 1. 
The changes in percentage usually are not large, except in States 
where new varieties have been developed or introduced recently. 
No attempt has been made to show the percentage of increase or 
decrease in actual acreages of the varieties between 1919 and 1924, 
because of the marked changes in total wheat acreage during the 
5-year period. 
The number of reports used in computing the data for each State 
in 1919 and 1924 is shown opposite the name of the State. The 
States are listed in alphabetical order, and the varieties are listed 
alphabetically under each State. An asterisk in parentheses (*) is 
shown in both the acreage and percentage columns opposite the name 
of any variety reported as grown but for which an estimate of acreage 
either was not given or if given was less than 0.1 per cent of the 
total wheat acreage of the State.
