GENERAL REMARKS ON FORAGE GRASSES 23 



shoes are placed upon the horses' feet to prevent them 

 from sinking into the soft soil during the mowing. The 

 most important grasses of these marshes are a kind of 

 bluejoint (different from the bluestem of the prairies), 

 and reed canary grass. 



The third kind of wild hay is derived from salt marshes. 

 Vast areas of salt marsh are found along the seacoast of 

 the United States, especially that of the North Atlantic. 

 The hay derived from salt marsh is usually of poor 

 quality for forage but is utilized extensively for packing 

 and stable litter. 



GRAIN HAY

 standpoint, grain hay attains prime importance only on 

 the Pacific Coast and portions of the area lying to the 

 eastward. The lack of other sources of grass hay in this 

 region has led to the utilization of grain. Besides the
