in the production of grain and straw. The experiment has therefore 

 been conducted for six years in succession. The following table 

 gives the quantities of oats and barley sown together, and the average 

 yield of grain per acre in the average of six years' experiments : 



We see by the foregoing figure ''^"'^ the greatest number of pounds 

 of grain per acre was produced from a mixture of one bushel of oats 

 (34 lbs.) and one bushel of barley (48 lbs.) per acre, or by a total amount 

 of 82 pounds of the mixed seed per acre. 



A Mixture of Oats and Barley With and Without Some Other 

 Grain for Seed Purposes. In 1902, in 1903, and again in 1904, an 

 experiment was conducted in duplicate in order to ascertain whether 

 the seed mixture of one bushel of oats and one and a half bushels of 

 barley per acre could be improved by the addition of a small quantity 

 of some other kind of seed. In addition to the standard mixture of 

 oats and barley, one-half bushel of grain was used in each mixture. 

 The following yields per acre show the average results of the two tests 

 for each of the three years as follows : 



lbs. 



Standard Mixture 2,509

" " " 22 pounds of Emmer 2,500 



" " " 28 " Flax 2,511 



" " " 30 " Black Hulless Barley 2,469 



The average results of this experiment for three years seem to 

 indicate that it is very difficult to surpass the standard mixture of bar- 

 ley and oats in yield per acre by adding small quantities of other kinds 

 of seed. If only one bushel of barley had been used instead of one and 

 a half bushels for the standard mixture, possibly the other seed might 

 have exerted an influence slightly more marked than is seen in the 

 results of this experiment. A mixture of oats, barley, and flax has 

 given very good satisfaction. 



Twelve Kinds of Grain Grown in Combination. In the spring 

 of 1902, an experiment was started in growing twelve kinds of grain 

 in different combinations. One of the principal objects of this experi- 

 ment was to ascertain the relative value of different kinds of grain 

 when grown in com'^'^'^tion in comparison with the same p-rains when 

 grown separately. The different grains used for this mixture were as
