Expoiieuce lias sbown tbatinthe Sontberu States all permanent grasses and clovers 

 do best when sown in the fall, from August 15 to October 1. * * * The use of 

 "nurse ciops," either of cereals like oats or of some growing annual grasses like 

 Italian rye grass, is now disapproved by the best authorities. Such nurse crops really 

 act as weeds, fimothoring out the plants they were meant to assist and disappearing 

 themselves at the end of a year or two, leaving the sward open for other weeds to 

 come in. The soil for grass fields requires careful preparation. * * * A good 

 preparation for a permanent grass field is a crop of cow-peas, heavily fertilized with 

 potash aud i)hos[tliate, planted in spiring and plowed under in August. * * ' Most 

 grasses root shallowly and soon exhaust the top layer of the soil, -whereas red clover 

 and lucern root deeply, feeding upon the lower layers of the soil, and in addition add 

 to the soil nitrogen taken from the air.
