J 30 Mr. Curwen on the Means of 



estimated under two-pence ; notwithstanding the disparity of cost, there is still a 

 greater difference in their nutrition. What I wintered as above, upon the refuse 

 of green food, were in condition for killing two months earlier, and exceeded any 

 of the same kind I ever had, both in weight of carcase and tallow, and brought 

 from two to three pounds per head more than I had ever obtained before. 



The plan I have followed in estimating the profits upon the experiment, is, in 

 the first instance, to put a value upon the green crop, supposing it to be old by 

 the farmer to the milkman. I have afterwards united the two profits. I may be 

 supposed to have over-rated the cost as well as the value of the green crops ; this, 

 however, is matter of opinion, and must depend in a great measure upon situation. 

 The cost of cleaning drilled turnips much exceeds the broadcast, yet I have no 

 doubt whatever, the weight will amply compensate for the expense; and, when the 

 drill husbandry is properly attended to, will greatly exceed the general estimate of 

 fifteen tons per acre. I shall endeavour to ascertain this fact against another year. 



The apparent profit upon the milk, falls short of what I expected, and what I am 

 confident it might and ought to have been, under proper management. It is 

 sufficient, however, to encourage the hopes at first entertained of the practicability 

 of the measure, and to determine me to proceed with the experiment. 



With the experience I have gained, I have no doubt I shall exhibit a very dif- 

 ferent result of profits in the next year's trial.
