be well worthy of attention on the part of farmers and 

 ranchmen in areas wherein agriculture is more or less 

 dependent on the successful growth of this grass. The 

 interval between the sowing of the seed and the first re- 

 newal by this process and between subsequent renewals 

 should be determined by the necessity for the same, as 

 evidenced by undue matting of the grass accompanied 

 by a deficiency in growth. 



Destroying Russian Brome Grass. — In some localities 

 some difiiculty has been found in getting rid of this 

 grass when meadows or pastures are broken; especially 

 is this true of rich and moist soils. Where this danger 

 exists, either of the two following methods will prove 

 effective: — First, backset the sod as in breaking up the 

 prairie, that is, plough it shallow in June and deeper 

 later ; or, second, plough reasonably deep and with care, 

 and follow with a well cultivated crop of corn. But it 

 would seem to be correct to say that no one who desires 

 to sow this excellent grass should be deterred from sow- 

 ing it from fear that it would make trouble by persist- 

 ently remaining in the soil.
