378 GRASSES AND HOW TO GROW THEM. ' 



the grazing. This mixture will not likely provide suf- 

 ficient pasture on poor soil to justify sowing it on the 

 same. Bermuda grass will serve the purpose better. 



On bottom lands and alluvial soils, such as are found 

 in river basins, the same formula will answer but it 

 may prove helpful to add to it 2 pounds each per acre 

 of perennial rye grass and meadow foxtail. 



For the Canadian Northwest. — For the provinces in- 

 cluded in this group, see p. 346. The best single per- 

 •manent pasture grass for this entire area is Eussian 

 brome. How long it may be grown on the same land 

 without decrease in the yield, has not yet been proved 

 but when renewed by suitable harrowing and ploughing 

 every few years (see p. 188) it would last for many 

 years. 



The best mixture of grasses for permanent pastures at 

 the present time is the following : 



Lbs. per Acre. 



Russian brome 6 



Western rye 6 



Timothy 6 



Total 18 



In dry areas, it would probably be preferable to sow 

 only Russian brome as timothy will not do well in 

 these; where Russian brome is sown alone, it may be 

 renewed, as indicated above* so as to make it perma- 

 nent. In some of the moister sections of the group 

 of provinces, it may be helpful to add a few pounds 

 of redtop to the above formula and in others a few 

 pounds of Kentucky blue grass; but it would not avail 

 to sow either, where the rainfall is light nor is it wise
