GRASSES AND CLOVERS 



permanent mixtures are being formed, to allow for imperfections 

 in the seed-bed, season, and other causes which tend to prevent 

 proper germination, and kill off seedlings before they are estab- 

 lished. Column IV. gives the weights to be used in such cases. 

 While we consider that an addition of seeds beyond those 

 deduced from these figures sometimes pays for the increased 

 outlay, especially when laying down permanent pasture, we are 

 convinced, from practical experiment and observation, that the 

 quantity of seed recommended by most seedsmen is much 

 greater than necessary where good seed is employed.
