OP CROPS USUALLY CULTIVATED. 281 



A new plant of the turnip sort has been lately introdu- 

 ced into Scotland, called noll-kholl. It rises like a cab- 

 bage plant till it is about three inches high, then forms 

 like a Swedish turnip, and appears to be much of the na- 

 ture with 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 have seen them in great perfection at Lord Lauderdale's, 

 near Dunbar. A correspondent informs me, that they are 

 cultivated in Strathearn, and that the sheep preferred them 

 much to turnips. 



3. The produce of the turnip crop necessarily varies. 

 Mr Paterson of Castle-Huntly found that his globe or 

 common turnip weighed fifty tons per Scotch, or forty per 

 English acre, when entire, but only forty-six tons when the 

 tops and tails were cut off. Mr Allan of Craigrook states, 

 that on his farm at Oldliston, the common white turnip 

 weighed from forty to fifty tons per Scotch acre. The 

 Swedish turnips also, when properly cultivated, produce a 

 heavy crop. I am informed, from undoubted authority, 

 that a Scotch acre of that sort, in East Lothian, weighed 

 no less than forty-four tons, which is at the rate of about 

 thirty-seven tons per English acre. The crop appeared so 

 great, that several respectable farmers in the neighbour- 

 hood attended to see it weighed. 



In regard to the weight of turnips on the different soils, 

 Mr Rennie of Phantassie states, that in the best land, 

 worth L. 5 per Scotch acre, the produce may be forty 

 tons, which is at the rate of about thirty-two tons per Eng- 

 lish acre. Where the land is of inferior quality, the pro- 

 duce must necessarily be less. The profit to be derived 

 from such a crop, must depend upon various circumstan- 

 ces ; the value is generally calculated at 5 s. per ton to the
