On ihe Use of the Sward-Dresser. 



JL HE use of this machine is to scarify and dress meadow land, whether it is to 

 be mown or depastured. 



The best time of performing this operation is from the middle of February 

 to the middle of April. 



In general, dressing the land one way is sufficient; but if the sward be very 

 mossy, or adhesive, it should be dressed length and cross ways, cleaned, 

 and then rolled. 



Previous to turning the machine, the left hand fore corner must be lifted 

 up and propped, and the coulters cleaned. 



If the sward be thin, it may be thickened very much, by laying eight or ten 

 tons of rotten dung, and sowing seven pounds of white clover, four pounds of 

 wild or cow clover, four pounds of trefoil, four pounds of rib grass, and one peck 

 of best rye grass seeds per acre, previous to its being dressed, or bush harrowed*
