Farming of Cornivall.

ressfully practised for many years in Probus, on Trewithen^ Barle- 
liver, and other farms. Mr. Tremayne, of Heligan, Las written 
a very interesting paper on the cultivation of rape in Cornwall, in 
this Journal. He imagines, and very justly too, that a great 
part of the expenses of the wheat crop may be saved — particu- 
larly the lime hill — by the growing of rape and feeding of sheep. 
The cost of growing an acre of rape and wheat as practised on a 
coarse piece of land mny be thus stated : —

The cultivation of the wheat ci'op by the old method, in the 
cheapest manner, can never be done much under 5/., and when 
Olid hi good condition. The ploughing need not take place until March or 
April, which may be accomplished in wet weather when ijo other field 
work can be pertoimed. The expenses of cultivating a crop of rape by 
this method are as follow : —

The skim-coulter may be screwed at any fixed height, so that in its 
progress through the ground it pares ofl' the surface at the requisite depth, 
turns it over, and the slice thus cut olf is buried by the common share 
of the plough beneath the soil. ' It is easily worked by two good horses, 
the draught not being more than 4 cwt. Another advantage in the use of 
this plough is, that in addition to the saving of labour, the land may be 
pastured up to the time of sowing. Very little harrowing is required, and 
the soil is in a better state to receive the seed than can be possibly ob- 
tained by any other method. I have seen wheat, barley, oats, turnips, 
and potatoes also, cultivated in this manner.
