wise ; that is to say, to divide the seed into two parts, to sow 

 one half in one direction, and the other half at ri^ht angles 

 over it. This plan can, however, not he adopted on steep 

 ground. Light seed should not he sown duiing windy 

 weather, else it will he unevenly distrihuted. 



^Vhere seeds of two species are to he sown, they should 

 be thoroughly mixed hefore sowing ; if tliey differ in size or 

 weight, it is best to sow them separately, or one cross-wise 

 over the other. 



Heavy seed may be placed in plough furrows, or singly 

 l)rought into the ground.

The method of covering the seed depends on the mode 

 of working the soil and the size of the seed. In the case of 

 shallow working and light seeds, the harrow and rake are 

 the most useful tools to use ; in some cases it may suffice 

 to drive a flock of sheep over the area, wbich will press the 

 seed into the soil by trampling on it. Where heavy seeds 

 are to be covered on level ground, the operation may be done 

 by ploughing, or with the rake or hoe.

Broadcast sowing is generally expensive, owing to the cul- 

 tivation of the soil and because it requires a large quantity 

 of seed ; hence it should be restricted to localities which 

 require little or no cultivation, or where a raw soil and a 

 strong growth of shrubs and weeds necessitate under any 

 circumstances a thorough cultivation, before success can be 

 expected. In some cases the operation may be combiiu'd with 

 the raising of one or more field crops, thus recuu})ing the 

 cost of cultivation.
