CONCLUSIONS. 
The data in Tables XXI to XXV, inclusive, and in figure 7 show 
that the Marquis variety has not proved a high yielder at any station 
west of the Rocky Mountains. At three stations in Utah, Idaho, and 
Oregon, winter wheats outyield all spring wheats. At all five stations, 
other spring wheats outyield the Marquis. It is not as good, on the 
average, as the Palouse Bluestem, Early Baart, Fretes, or Ghirka 
Spring. It also is not as good as several of the new wheats which have 
been tested at these western stations but are not yet grown commer- 
cially. Marquis wheat is not recommended for any district west of 
the Rocky Mountains. 
Results in Irrigated Districts. 
Irrigated farming is confined to the valleys more or less adjacent 
to the mountains of the Western States. So far as known, Marquis 
wheat has not been grown commercially under irrigation. 
Experiments to determine the value of Marquis wheat under irri- 
gation conditions have been conducted at four different points. 
Two of these are east and two west of the Rocky Mountains. The 
stations are Newell, S. Dak.; Huntley, Mont.; Aberdeen, Idaho, and 
Fallon, Nev. The location of these four stations and the average 
yields of Marquis wheat and of the best variety in each of several 
groups of wheat are shown graphically in figure 10. The annual 
and average yields of the Marquis and several other varieties will be 
found in Tables XXVI to XXIX inclusive.
