were tested for at least five years. A few varieties have now been 

 grown for fifteen years in succession, without change of seed. The 

 results of these varieties are exceedingly interesting and worthy of 

 careful study. The following are the average yields of grain per acre 

 of each variety for the whole period of fifteen years, and also for the 

 last five years :

The results show that the Mandscheuri gave decidedly the great- 

 est yield per acre of the four varieties for the whole period of fifteen 

 years, and also for the last five years. The Mandscheuri gave an aver- 

 age of 9.3 bushels per acre per annum over the Common Six-rowed 

 barley in the average results for fifteen years. The average area devot- 

 ed to barley in Ontario from 1882 to 1904 is given as 633,290 acres per 

 annum. An increase of nine bushels of barley per acre throughout the 

 Province would, therefore, amount to an increase of over five million 

 bushels of barley in Ontario annually. This increase at fifty cents per 

 bushel would amount to about two and a half million dollars. Two 

 and a half million dollars annually would pay the running expenses of 

 about thirty Agricultural Colleges like the one located at Guelph. The 

 Mandscheuri barley was imported from Russia by the Ontario Agricul- 

 tural College in the spring of 1889. Not only has it made a very ex- 

 cellent record at the College, but it has given high results in the co- 

 operative experiments throughout Ontario and has been grown in gen- 

 eral cultivation very successfully during the past few years. In looking 

 up the records of the Bureau of Industries, we find that the average 

 yield of barley throughout the Province for the period of ten years from 

 1895 to 1904, inclusive, is 29.3 bushels per acre; while that for the 

 period of ten years from 1885 to 1894 inclusive was 24.85 bushels per 

 acre. This shows an annual average increase of about 4 1/2 bushels 

 per acre for the latter as compared with the former period of ten years. 

 From these results, does it not appear as though the introduction of 

 the Mandscheuri barley by the Ontario Agricultural College has been 

 worth to the Province of Ontario within the past ten years an annual 

 money value equal to more than fifteen times the entire cost of the 



College? 



Among the other varieties of six-rowed barley which have been 

 grown in the Experimental Department besides those already re- 

 ferred to, mention might be made of the California Brewing, Scotch Im-
