DESTROYING WEEDS.

The best method of sowing clover and timothy 

 seed A%'ith grain, when the grain drill is used, is to 

 sow the clover and timothy in front of the grain 

 spouts, or tubes, so that it will be scattered on the 

 surface. After sowing, give a stroke with the 

 harrows or Breed weeder crossways to smooth 

 the surface. - See III. 66. 



Do not roll until the land is thoroughly dr\', even 

 if by that time the grain is two or three inches high. 

 If the land is rolled in the early spring when it is 

 damp, a crust is liable to form which will encourage 

 capillar}^ attraction and so cause the moisture in 

 the soil to rise to the surface and become evapor- 

 ated. Rolling after the land has been thoroughly 

 dried prevents this, as the lumps of earth on the 

 surface are then pulverized, thus forming a mulch 

 which prevents evaporation. 



To further increase the humus in the soil cut the 

 clover early the following year for hay, say about 

 the middle of June. When the second growth is 

 coming into bloom, plow under about four inches 

 deep, using a revolving coulter and chain as before 

 described. Roll, and harrow thoroughly. 



In about two weeks the sod will be sufficiently 

 rotted to cultivate with a spring-tooth cultivator. 

 By cultivating several times with mde points, and 

 harrowing alternately during the summer and early 

 fall, all weeds and weed seeds should be destroyed. 



In the autumn, spread over the surface ten or 

 twelve loads of farmyard manure per acre and rib as 

 before described. In the spring, when the ribs have 

 been levelled down, the manure and rotted clover sod 

 will have become thoroughly incorporated, making 

 the very best quality of vegetable matter for growing 

 crops of all kinds. Land treated in this manner will be 

 in good condition to grow abundant crops continuous- 

 ly, provided a systematic rotation of crops is followed.
