On the Kohl-Rahi. 
forgetting to push all weeds away from the tufts. A week or 
ten days afterwards, the rows may again be gone over, and the 
tufts singled by hand, taking care to leave the strongest plant. 
The expense of performing the operation in this way is greater, 
but it is the most economical method in the end. 
Management of the Crop. 
While growing, the land should be kept very clean and free 
from weeds ; and, to insure this, the horse-hoe should be in con- 
tinual requisition. The plants arrive at maturity in about twenty- 
five weeks, when they may be pulled or stored like other root 
crops. 
Stoking. 
Although the Kohl-Rabi is capable of withstanding the most 
intense frost, it is desirable to have it stored for winter use. 
Topping, in the usual mode of preparing swedes for storing, 
may be followed. The tailing process may, however, be omitted 
with advantage. 
Weight of Produce. 
In our own experience, a crop of 25 tons per acre is a very fair 
average. In stating this weight it should be borne in mind that 
the observation applies to the neighbourhood of Edinburgh. 
Further south it is within our knowledge that from 30 to 35 tons 
have been grown, of the oblong green variety (No. 5). Last year 
Mr, Innes, factor to Colonel North, gave us the following result 
of the produce of his crop ; and, although the great abundance of 
leaves in the green (late) variety gives the greatest gross weight, 
he prefers the early purple for feeding purposes, the weight of 
the bulbs being nearly 2f tons per acre in excess of the green : —
