The gain in cai^case ^veigllt I estimate as 14 lbs. per week. 

 „ in loose fat 3 ,, 



Whole gain per week 17 lbs. 



I may here remark, that if the feeder expect a weekly return 

 equal to the price of the whole of the gain in live weight, he is 

 likely to be mistaken. Though favourably situated for the pur- 

 chase of stock, I am seldom able to purchase lean stock, which, 

 if killed at the time of purchase, would not, in accordance with 

 the computation stated, cost more per lb. than the price of fat 

 stock at the same time. The difference in my case will be from 

 30^. to 40^. per beast, which will be a deduction of \s. ^d. to 2s. 

 per week from the earnings reckoned on the gain of live weight. 



In addition to the interior fat, tallow, and suet, there is an in- 

 crease in the fat of the beef, and of that mixed with the flesh. 

 That this increases in a greater proportion than the flesh seems 

 clear, as fat beef is a term used to signify beef having a greater 

 proportion of fat to flesh. I am therefore disposed to estimate 

 the gain per week as composed of 



lbs. 



Loose fat or tallow, per week 3 



Fat with beef and suet in the loin 8 



Fibrine or flesh 6 



Total gain per week 17 



As flesh contains 77 per cent.* moisture, the weekly gain for each 

 in dry material will be —
