are noticed, the lime, half a bushel per rod, eighty 

 bushels per acre, being applied as soon as slaked with 

 the smallest quantity of water necessary to cause it to 

 fall into an apparently dry powder, and work it into 

 the soil with hoes. 



Lime (stone lime preferably, as it acts more power- 

 fully than that made from chalk) has been proved 

 frequently to be a preventive of club-root. It should 

 be applied hot to infected land and dug or ploughed in 

 to the depth of three or four inches. A dressing of 

 stone lime every eight or twelve years has secured 

 immunity from the disease, while where chalk lime 

 has been used the dressing must be repeated every 

 four, or at most eight years. Eighty bushels per 

 acre, half a bushel per rod, of quick lime is the proper 

 quantity. As the plants are most susceptible to the 

 disease shortly after germination, it is a good practice 

 to dress the land before sowing or planting with forty 

 bushels per acre, or half a bushel per rod, of hot lime, 

 particularly land liable to club-root. When a Brassica 

 crop is affected, this is usually sufficient to arrest the 

 disease. 



In bad cases, and where procurable, gas lime, fresh 

 from gasworks, at the rate of two to four tons per 

 acre, quarter to half cwt. per rod, will be found more 

 efficacious than ordinary lime, broadcasting it evenly 

 after the diseased crop is cleared, or in autumn in 

 advance of preparing for cropping. Leave it on the 

 surface a month or six weeks before digging or plough- 

 ing in ; this has been found a complete cure and pre-
