niixturcH of l^ bn. oats and Ih Im. l)arU'y also produced tlie best average yields of 

 straw. In 1902 a mixture -of 1 l)u. of oats and IJ bu. of barley was compared with 

 several mixtures containing the same quantities of oats and barley, and in addition 

 I bu. of either Wild Goose spring wheat, emmer, grass peas, or flax. The experi- 

 ment was conducted in duplicate and the average yield of oats and barley was 2,183 

 lbs.; of oats, barley, and spring wheat, 2,273 lbs.; of oats, barley, and emmer, 2,207 

 lbs.; of t)ats, barley, and grass peas, 2,159 lbs.; and oats, barley, and flax, 2,1<S0 lbs. 

 per acre. In 1 test equal quantities of seed of 12 different farm crops were sown 

 to determine how these crops would stand crowding. Beginning with the largest 

 yield of grain, the crops stood in the following order: Manshury barley, Joanette 

 oats, Black Hulless barley, Siberian oats, rye. White Hulless barley, emmer, Wild 

 Goose spring wheat, Prussian Blue peas, flax, grass peas, and common vetches. 



The results of treating oats and winter wheat for the prevention of smut are 

 reported. Untreated seed oats produced SJ per cent of smut in the crop. The hot 

 water and formalin treatments were very effective. The average results fur 4 years 

 show that untreated winter wheat contained 456 smut balls per pound of wheat; 

 treated with potassium sulphid, 11; with copper sulphate, 2; and with hot water, 1. 



A com])arison of leading varieties of different field crops grown xmdei" similar con- 

 ditions was made and the results ai'e given in the following table:

The results obtained with these same crops in cooperative tests throughout Ontario 

 show that the comparative order in yield of grain is very similar to that in the above 

 test. 



Red Fern and Red Fife spring wheat were found to be among the best vai-ieties 

 for the production of flour. The average of 10 years' results with macaroni wheats 

 gave the following yields: Wild Goose 38.4 bu., Medeah 33.8 bu., Bart Tremenia 

 33.4 l)u., Sorentina 33 liu., Algiers 31.4 bu., and Ontario 20.9 bu. per acre. For gen- 

 eral cultivation in Ontario Wild Goose is considered the leading variety. 



Descriptions of spelt and emmer are given and the results of culture tests are 

 reported. The following yields of varieties of spelt were obtained in 1902: Red 

 spelt 1,661 lbs., Alstroum 1,466 lbs., German spelt 1,420 lbs.. White Summer spelt 

 1,263 lbs. of gnain per acre. Emmer has been under test for 3 years, and has given 

 an average yield of grain per acre of 2,327 lbs. The weight per measured bushel 

 for the 3 years varied from 33.8 to 43.8, with an average of 38 lbs. Emmer gave 

 better results than spelt in an experiment at the college, and it is believed that this 

 crop will be more generally grown for feed for live stock. The results of variety tests 

 with spring rye, oats, 6-rowed barley, 2-rowed barley, Hulless barley, winter barley, 

 winter wheat, winter rye, buckwheat, and corn are reported. Dakota Mammoth, 

 Prolific Spring, Connnon, and Colorado Giant spring rye grown from 3 to 5 years 

 yielded on an average 40.2, 36.9, 34.9, and 25.8 bu. per acre respectively. In 1902, 

 72 varieties of oats were under test. Some of these varieties have been grown for
