to be superior to the original strain. The yields obtained from this 

 pure line are substituted for those of the original strain in Table 

 VIII, and the average yield is therefore greater than that of the 

 original stock shown in Tables VI and VII. Both C. I. No. 1440 

 and C. I. No. 40G3 have good milling qualities, but the volume of 

 the loaf is comparatively small. (See Pi. I.) 



Arnautl-a. — The variety Arnautka (C. I. No. 1494) is typical 

 of the durum wheat most commonly grown in North Dakota and 

 South Dakota. It is better adapted to the eastern portion of these 

 States. Arnautka is slightly taller than Kubanka, with longer, more 

 slender heads (fig. 4) and longer grain. It originally came from 

 Russia, where it is grown in the more humid territory bordering on

the Sea of Azof. The stock grown at Dickinson was obtained by 

 the United States Department cf Agriculture from Mr. T. N. Oiiim, 

 Lisbon, N. Dak., in 1900. It has often been called Goose wheat or 

 Wild Goose. The Arnautka wheat has yielded well in our trials, 

 but is exceeded in yield by the Kubanka. A pure-line selection 

 from Arnautka, Arnautka 6P1 (C. I. No. 4064), made at the Akron 

 (Colo.) Experiment Farm has yielded better than the original va- 

 riety and has been substituted for it in cur trials. In milling quality 

 the Arnautka is inferior to the Kubanka. 



THE FIFE GROUP. 



Among the varieties of the fife group which have been tested at 

 Dickinson the Ghirka Spring and the Rysting have given the best
