During the period from 1913 to 1919. inclusive. 109 cooperative 
trials of emmer in comparison with barley were conducted by farmers 
in Ontario under the supervision of Dr. C. A. Zavitz. The annual 
and average acre yields of the two crops, as reported by Zavitz (72). 
are shown in Table 20. The yields of barley exceeded those of emmer 
in each year, the average difference being 28 1 pounds per acre. 
Both emmer and spelt are less productive than either barley or oats 
in Ontario.

RESULTS AT OTTAWA, ONTARIO. 
Experiments with emmer were begun at Ottawa. Ontario, in 1901. 
From 1903 to 1914 rather extensive experiments with emmer. spelt, 
and einkorn were in progress. The results of these have been pub- 
lished by Saunders {39 and 41) hi the annual reports of the Dominion 
cerealist and are shown in Table 21. Xo emmer or spelt was grown 
in 1913. 
Vernal (White Spring) emmer yielded nearly the same as Red em- 
mer and somewhat more than any of the varieties of spelt. Two 
varieties of einkorn were grown at Ottawa during the period of the 
experiments, one from 1903 to 1905 and the other from 1906 to 1914. 
The Common variety outyielded both emmer and spelt during two 
of the three years it was grown. The Double einkorn yielded an 
average of 113 pounds per acre less than Vernal emmer during the 
eight years from 1906 to 1914 (1913 excluded.'. « 
The average acre yield of Vernal emmer during the 12 years from 
1901 to 1912. inclusive, was 2.001 pounds. During the same period 
Stella barley averaged 2.4S7 pounds and Banner oats 2.33S pounds 
per acre.
