grown wheats there were also tested in one two-thousandth acre 

 plots 7 pure strains of hard spring wheat which had been ob- 

 tained from Minnesota in the winter of 1916. The writer 

 wishes to express his appreciation of the courtesy of Prof. H. 

 K. Hayes of the University of Minnesota in sending these 

 wheats to him. The Minnesota strains included one representa- 

 tive of each of the following varieties : Bluestem (Haynes Blue- 

 stem), Marquis, Velvet Chaff, Royalton (Red), Royalton 

 (White) and two representatives of durum wheat, Speltz Marz 

 (Fig. 4) and Hedge Row. According to a written communica- 

 tion from Professor Hayes the Royalton wheat was originally 

 obtained from Royalton, Minn., and its origin was possibly a 

 natural cross. The two strains of this wheat are very distinct, 

 one (Royalton White) possessing a smooth chaffed spike and 

 white grain suggestive of the White Fife, while the other strain 

 (Royalton Red) produces a red grain and a hairy chaffed spike 

 similar to Bluestem. The spikes of these two strains are repro- 

 duced in Fig. 3. All the Minnesota strains have been given 

 Maine accession numbers 182 to 187. 



The crop from the one two-thousandth acre plots in 19 17 

 furnished enough seed from each strain to make a chemical 

 analysis of the crude protein content. A further scrutiny of 

 these pure lines on the basis of the chemical analysis and the 

 field notes resulted in the discarding of a number of strains 

 until 44 pure lines of Aroostook wheats and 6 pure lines of 



*Dr. Chas. E. Saunders, Cerealist at the Central Experimental Farm 

 at Ottawa, informs me that the variety here listed under the name Can- 

 ada Red is probably the variety called Black Sea (identical with Ladoga). 

 It is a bearded wheat, with smooth, reddish brown chaff and producing, 

 red kernels.
