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 

 jdeld 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.
