of A. R. Merritt. The results obtained are shown in Table XXIX. 
The average yield of the best variety in each group is shown graphi- 
cally in figure 10. The two farms used for these experiments are 
about 20 miles apart. The results obtained in the two different 
years are not directly comparable. Since they agree fairly well, 
however, they have been averaged in Table XXIX and in figure 10. 
Only spring common wheats have been compared with the Marquis 
in Nevada. Table XXIX shows that the Palouse Bluestem, Dicklow, 
and Little Club all outyield the Marquis by large margins. The 
overyields amount to 22, 28, and 33 per cent, respectively.

CONCLUSIONS. 
In Idaho and Nevada the soft white spring wheats, Dicklow, 
Defiance, Palouse Bluestem, and Little Club, all have outyielded 
the Marquis under irrigation. The Marquis wheat is not a profitable 
variety to grow under irrigation west of the Rocky Mountains. 
In western South Dakota and in Montana the Marquis has given 
good results in comparison with other varieties of spring common 
wheat. The few data available indicate that it does not yield as 
well as the Kubanka durum and the Kharkof winter wheat. 
SUMMARY OF YIELD DATA. 
For convenience of comparison a summary of the average yields 
is presented in Table XXX. This summary contains the average 
yield of the most productive variety in each group at each station 
where it was grown. In all, 23 stations are represented. There are 
25 different sets of experiments, however, as the varieties were grown 
under both nonirrigated and irrigated conditions at two stations. 
The Marquis and representatives of eight other groups are included. 
The average yields of the same varieties at the same stations are 
also expressed in Table XXX in percentages of the yields of the 
Marquis variety. Arranging the data in this form makes compari- 
son still more easy.
