AFIUL.] DRILL CABE AGE-SEED. 



only be performed in, or immediately after rain, 

 and in case of a drought, must be postponed till 

 a good crop may be unattainable. They should, 

 in the drill system, follow some hoeing or cleansing 

 crop, such as turnip, a previous crop of cabbages, 

 potatoes, tares, beans or pease, &c. I suppose the 

 land, in the case of its having yielded turnip or 

 cabbage, to have been ploughed the moment the 

 produce was consumed, into such ridges as are in- 

 tended for the cabbage-seed, either three or four 

 feet wide. If any of the other crops preceded, 

 this ploughing should have been given before the 

 Christmas frosts. Into the farrows of these ridges 

 the dung, 30 cubical yards an acre, in no case less 

 than 20, should be laid in March, and the ridges 

 reversed directly, covering up the manure and form- 

 ing new ridges. They should then be left for 10, 12, 

 or 16 days, to the influence of the atmosphere. In 

 that state they lie sound and safe from rain. When 

 it is intended to drill, harrowing should precede, 

 or it may be omitted if the soil is very friable and 

 in fine order, as the roller to which the drill is at- 

 tached will level the crowns sufficiently, and they 

 should not be reduced too much. The Northum- 

 berland drill is to be hung to a roller eight feet 

 long for four feet ridges, or six feet long for three 

 feet ones. Staples are in the frame of the roller 

 for this purpose, and a chain hooks the drill to 

 them. The roller covers the ridge drilling, and 

 one in advance to be drilled by the next turn. So 

 going on constantly, four pieces of a kitchen jack
