WINTER-WHEAT PRODUCTION AT FORT HAYS STATION. 5 
The average yields of winter wheat per acre each year in each of 
the five counties, Ellis, Russell, Rush, Rooks, and Trego, are pre- 
sented in Table 3. In the last column of the table the average yield 
of the five counties for each year is given.

If these yields are studied as a whole by determining each year the 
average of all yields available at that time, a generally falling average 
yield is shown. The decrease, however, is becoming very small in 
recent years. Such a study alone would lead to the conclusion that 
yields are decreasing. But a further study shows that this apparent 
continuing decrease is due entirely to the persistent effect on the 
average of the high yields obtained in the early years. The high 
yields in the early years are shown most effectively in Table 4. In 
this table the yields given in Table 3 are averaged by decades and 
partial decades. In this table, as in these statistics in general, the 
evidence of each county is confirmed by that of the others. 
The average of the five counties shows for the 7-year period from 
1874 to 1880 an average yield of 14.1 bushels, for the decade 1881 
to 1890 an average of 14.4 bushels, for the decade 1891 to 1900 an 
average of 9.6 bushels, for the decade 1901 to 1910 an average of 10.4 
bushels, and for the decade 1911 to 1920 an average of 10.8 bushels. 
This shows a higher average in the seventies and eighties than has 
been attained since and indicates a maintenance of yields during the 
three later periods. This phase of the question will be studied more 
in detail than simply by the decade averages.
