Whence the profit of a cow for a year is 8l. 19s. 5d. or 9l. 



The most important consideration in this estimate is the small quantity of land required, and the use, 



which the kind of food here used is put to. The same quantity and quality of food could not produce so 



much profit by grazing. Mr. Curwen grinds the oil cake, and boils it with the chaff, &c. and finds that 



tliree acres of green food is sufficient for 30 cows, 200 days, giving to each 2 stones per day. By this 



o/,. mode of feeding, Mr. Curwen sold last year £. s.

Now let us ask how many acres of green food are necessary for 30 cows 200 days, by the common 

 method of feeding. Will not each cow require | of an acre of turnips from October to April, besides 

 straw? If so, 30 cows require 22^ acres of land for less than 200 days. By Mr. Curwen's method of 

 feeding then 195, nay, we may fairly say, 20 acres of land are saved for stock of a different kind, or for 

 such purposes as the farmer thinks proper to put them to. 



, In what way this method of feeding cows may be improved for Norfolk farmers requires experiment 

 and fact to shew — Mr. Curwen has great merit in practising it to the extent he does. It is only wonder- 

 ful he does not appropriate the savings, which are so manifest upon his farm, to the support of breed- 

 ing ewes. I must not, however, indulge either a splenetic or a conceited temper — I went into Cum- 

 berland not to be peevish and fretful at what I did not find, but to admire what was beautiful, and to 

 select what was serviceable — and I tliink after the means of using economically the food of horses, I saw 

 the means of lessening their number. 



Whatever can be carried to market will have a value set upon it by that market, but what cannot be carried to market 

 can be valued only by that which can be carried to market in its stead. For instance, if I grow a crop of carrots and can 

 get no market for them, they are of no value to me, unless I feed animals with them and carry those animals to market, 

 or horses, and carry to market the corn or hay, &c. which those horses must have consumed instead of the carrots. 



* i. e. From October to April, when chaff and coulder and broken straw can be supplied them. 



t Mr. Curwen sells his cows as they become old or unproductive, and all his calves, and buys young cows.
