follows : Mandscheuri barley, Black Hulless barley, Springs rye, 

 Earlv Alaska oats, field peas, Joanette Black oats, White Hulless bar- 

 ley, Emmer, Grass peas, Wild Goose spring- wheat, vetches, and 

 flax. The mixtures were made up in two different ways — first, by using 

 the same amount of seed of each variety which is usually sown when 

 the grains are grown separately, and second, by using equal quantities 

 of seed of all the varieties. Each of the mixtures here described was 

 sown at the rate of 56, 84, 112, 140, and 168 pounds of seed per acre. 

 Each part of the experiment was conducted in duplicate. It will there- 

 fore be seen that there were four tests made with these different mix- 

 tures in each of the four years, and that sixty plots have been used for 

 the test durine the years 1902, 1903, and 1904. The average results 

 for the thrpf^ years show that 112 pounds of the mixture of seed per 

 acre produced a greater yield of grain than either of the two lighter 

 or the two heavier seedings. 



The crop produced by the mixture of twelve kinds of grain and 

 sown at the rate of 112 pounds per acre was carefully analysed in order 

 to ascertain the percentage of yield of each of the separate crops. Those 

 varieties which had the largest average percentage of seed in the crops 

 produced were as follows : Mandscheuri barley, Black Hulless barley, 

 Spring rye, Joanette Black oats, and Early Alaska oats. These five 

 varieties furnished about two-thirds of the entire crop ; while the other 

 third was produced by the White Hulless barley, field peas. Grass peas, 

 Emmer, Wild Goose spring wheat, Common Spring vetches, and flax. 

 The Mandscheuri barley had the largest and the flax the smallest per- 

 centage in the crop produced from the mixture of the twelve varieties. 

 This experiment goes to confirm other experiments, and to show that it 

 is very difficult to make a mixture which will produce a heavier yield 

 of grain per acre than one mgde of barley and oats. 



Varieties of Oats and Barley for Growing in Combination. 

 If oatq -nr^ barley are grown in combination, it is, of course, important 

 to secure those varieties which will mature at about the same time. 

 In order to do this, it is necessary to use a very early variety of oats 

 with an ordinary ripening barley, or a very late variety of barley to 

 use with an oat which matures at an average date. Of all the varieties 

 which we have used in combination, we have found that the Early 

 Daubeney oats and the Mandscheuri barley make a very excellent com- 

 bination. Another mixture which has given good satisfaction is the 

 Siberian or Banner oats and the Chevalier two-rowed barley. It is, 

 however, difficult to secure true seed of the Chevalier barley in Ontario 

 at the present time. Taking everything into consideration, the first 

 mixture here mentioned is one of the most satisfactory to use at the 



present time. 



Mangels. 



The number of acres used for the mangel crop in Ontario has been 

 greatly increased within the past tw^elve years. According to the
