Oft 



object with the skilful agriculturist will be, to keep the 

 land clear of weeds of all sorts, and summer fallow 

 has ever been found the only sure method of doing so. 

 Hitherto no plant has been found so well fitted to permit 

 that as the field turnip, which may be drilled, with the 

 best prospect of success, from the first week of June, to the 

 second week of July inclusive, giving full time to prepare 

 the land, which, together with the ploughings in the rows 

 among the turnips, completes the fallow in the most per- 

 fect manner. 



This states the question fairly, and if any plant could 

 be pointed out r that would an ,wer as well on strong land, 

 as turnips does on light land, fallowing, in so far as re- 

 gards the extirpation of weeds, would, with a drilled 

 crop, be as little necessary in the one case as in the 

 other *. 



In the Carse of Gowrie also, fallowing w considered to 

 be indispensable. 1 hat operation, it is said, by the fre- 

 quent winter and summer ploughings and harrowings, 

 meliorates the ground, makes it of a kindly texture, 

 cleans it of weeds, &c , enables it to receive the manure 

 in a proper dry season, and allows time for all the small 



* Perhaps the newly imported plant called noil-kali, may 

 answer the purpose. Mr Buist, overseer to Lord Haddin- 

 ton at Tynninghame, is of opinion, that it may answer on 

 strong soils, in place of a turnip crop. It rises like a cabbage 

 plant till it is ab<mt three inches high, then forms like a 

 Swedish turnip, and appears to be much of the nature of that 

 useful plant. They were first raised in East Lothian by 

 Mr Alexander Johnston, surgeon in Dunbar, who some 

 years ago received a few seeds from General Sir David 

 Baird, on his return from the Cape of Good Hope. I w 

 them in great perfection at Lord Lauderdalc's, near Dun- 

 bar.
