of keeping the five cattle on raw food was $154 10, 

 while that of the cattle on prepared food was 

 $164 40. On being slaughtered the two lots appear- 

 ed to be very similar, but the particular weight is 

 not mentioned. 



3. Relative economy of feeding with turnips alone, or 

 with turnips and other more expensive food. 



Robert Stevenson was the successful competitor 

 for the society's premium. He took 18 oxen ; their 

 live weight was ascertained at the beginning, at the 

 end, and at intermediate periods of the experiment, 

 which continued 1 19 days. The cattle were divided 

 into three lots of six beasts each, and a correct ac- 

 count was kept of the weight of food consumed by 

 each lot. Lot 1 was allowed linseed-cake, bruised 

 beans, and bruised oats, in addition to turnips, and 

 during the last 24 clays of the experiment, 20 Ibs. of 

 potatoes were given per day to each. Lot 2 receiv- 

 ed the same allowance except the linseed-cake and 

 half the potatoes. And lot 3 was fed upon turnips 

 alone. The cost of the keep of each animal, during 

 the 119 days, was as follows : 



Total cost of feeding one beast of lot I . $24 62 

 do. do. do. of lot 2 . 18 48 



do. do. do. of lot 3 . 9 27 



The improvement in live weight was as follows : 

 First lot increased in weight . 108 stone 

 Second do. do. . 101 " 



Third do. do. . 49 " 



Abstracting the cost of feeding from the value of 

 the increased weight, the loss and profit would stand 

 as below : 



Loss on feeding lot 1 - . . $18 00 



Profit on feeding lot 2 ... 953 



Profit on feeding lot 3 ... 1226 



" Thus, when turnips alone were used, a profit of 

 twenty-two per cent, was realized ; where beans and
