and average yields obtained from the Marquis and four other varie- 

 ties of wheat are given in Table XXVI. The average yield of each 

 variety is shown graphically in figure 10. 



The Marquis wheat has been compared with durum wheats and with 

 varieties of common wheats of the Fife, Bluestem, and White Austra- 

 lian groups. The last named group consists of soft white wheats, ex- 

 tensively grown west of the Rocky Mountains aiid represented at NeweU 

 by the Defiance variety. The Kubanka durum outyields the Marquis 

 by over 20 per cent. The Marquis, however, outyields the Power by 11 

 per cent, and the Haynes and Defiance by 25 and 30 per cent, respec- 

 tively. The Marquis has been compared with winter wheat only in 

 1915, when the Kharkof, a Crimean or hard red winter wheat, yielded 

 nearly four times as much as the Marquis.

RESULTS AT HUNTLEY, MONT. 



The experiments at Huntley are conducted cooperatively by the 

 Ofiice of Western Irrigation Agriculture and the Montana Agri- 

 cultural Experiment Station, The data here presented have been fur- 

 nished by the Agriculturist in Charge of the Office of Western Irriga- 

 tion Agriculture. The Marquis variety has been grown in varietal 

 experiments during only two years, 1913 and 1914. The annual and 

 average yields are given in Table XXVII. The average yield of the 

 best variety in each group is shown graphically in figure 10. 



At the Huntley station the Marquis variety has been compared 

 only with spring common wheats. It has outyielded Pringle Cham- 

 plain by 4 per cent; Stanley, a beardless variety with brown glumes, 

 by 25 per cent; and Dicklow, by 32 per cent.
