The data in the preceding tables have been averaged for comparison 

 with the averages of previous years as well as of those wheats which 

 had been grown different lengths of time in Colorado. 



An rage composition of Colorado wheat grown in 1884. 



The average for the seventy-seven varieties grown in 1884 when 

 compared with that of other years shows that in size and percentage of 

 albuminoids, although there has been an advance over 1883, the wheats 

 of that year are not equal to those of 1881 and 1882. 



Avtrage composition of Colorado wheats. 



It would perhaps be unsafe to draw any definite conclusions from 

 these averages, but they would seem to show that peculiarities of sea- 

 son are most influential on the composition of the grain. 



Examined in connection with the individual analyses and with regard 

 to the characteristics of the several seasons of growth it would appear 

 that the low percentage of albuminoids in 1884 may be due to the fact 

 that having fallen to 11.74 in 1883, the wheats were unable to recover 

 more than to 12.53 in 1884. If this is the case the effects of this bad 

 season and set back in 1883 may be overcome in 1885. Analysis of that 

 year's crop will decide this. 



Then, the inquiry may be made as to what influence on this average 

 is due to the continued growth of the grain on one soil for a number of 

 years. To examine this question the averages by seasons of growth 

 were calculated. From these one learns that the wheats of the first two 

 seasons growth are richer in albuminoids than those which have been 

 raised a longer time in Colorado. In the case of the wheats grown for
