TEMPORARY PASTURES. 339 



For Sandy Lands. The range of adaptation in cul- 

 tivated grasses for sandy or gravelly lanjds is not wide 

 and it narrows as the conditions become drier. For 

 temporary grazing on such lands, winter rye, not a 

 grass in the ordinary use of the word, will furnish 

 more pasture than anything else. Of the true and 

 valuable cultivated grasses, Russian brome stands first 

 in adaptation for such situations, but even this grass 

 will not provide abundant grazing on such lands. Where 

 moisture is ample, the production on these lands may 

 be greatly stimulated by fertilizing them and then 

 sowing red clover along with the grass. This is one 

 of the situations in which sowing quack grass seed 

 may in some instances be admissible in the North, and 

 velvet grass in the South, where Russian brome grass 

 does not succeed so well. In these southern pastures, 

 Japan and Buffalo clovers will prove helpful in sup- 

 plementing the grazing. 



It may also be found, especially in the dry uplands 

 of the West and Southwest, that it may be advisable to 

 introduce tall grama (Bouteloua racemosa) and blue 

 grama (Bouteloua oHigostachya) , but more experience 

 in growing these is wanted before pronouncing defi- 

 nitely with reference to this question. 



For Dry Areas. For dry areas such as those of the 

 semi-arid belt east of the Rocky mountains and in cer- 

 tain of the plains within the mountains, it is at least 

 questionable if any of the cultivated grasses will be 

 found any improvement over those which nature has 

 placed there. Nor has the fact been fully demon- 

 strated, that any of these can be established over wide
