these purposes because of its rapid germination and growth. It 

 should be looked upon as a temporary covering while more permanent 

 and valuable plants are becoming established. 



SOILS AND CLIMATE. 



For the best results this grass should have a fertile, moist soil with 

 a cool, damp climate. Hot, dry spells usually kill it on uplands, or 

 at least greatly retard its growth. Its lack of drought resistance 

 greatly restricts its usefulness in this countiy. 



CULTURE. 



The seed bed for Perennial rye-grass should be prepared as for 

 other grasses. A j&ne, mellow surface on a compact subsoil gives the 

 best results. It should be seeded early in the spring or in late sum- 

 mer or early fall. It does especially w^ell v^'hen seeded in the fall. 

 Its ability to grow off rapidly allows the plants to become well 

 established before hard freezing occurs. When seeded alone, from 

 25 to 30 pounds of seed to the acre are required to give a good stand, 

 while 8 to 10 pounds are sufficient for seeding in mixtures with other 

 grasses.
