This material, though of its kind particularly rich in nitrogen, 

 is not worth more as manure than 2s. Q\d. per 100 lbs., or less 

 than one-twentieth of its value as food. 



Tliese investigations, which have more or less occupied my at- 

 tention for several years, have changed considerably my mode of 

 treatment for fattening. I am satisfied that the inost economical 

 use of food rich in albuminous matter, is together with straw or 

 other materials which are deficient in this element. I now use 

 for fattening, bean and oat-straw and shells of oats in equal propor- 

 tions, with a limited supply of turnips^ never exceeding 60 lbs 

 per day to each, and the following extra food : 



3 lbs. of rape cake,_. ") 



I lb. malt combs, J- steamed together with the straw. 



3 



lb. bran, J 



If my turnips fail in spring, by supplying 2 to 2 J lbs. of rape- 

 cake in addition, I find the result equally favorable. On this fare 

 my cattle thrive satisfactorily, and make usually at the rate of 14 

 lbs. per week each. I sometimes substitute ^ lb. per day of lin- 

 seed oil for the 2 lbs. of rape-cake without turnips, the gain by 

 which I find satisfactory. One of a lot of 14 fed in this mode 

 gained at the rate of 24 lbs. per Aveek from March up to July, 

 1856. being the greatest gain I have observed in the course of my 

 experience as a feeder. 



Having received numerous applications from vendors to become 

 a purchaser, and inquiries as to what I thought of the properties 

 of carob or locust beans, I may call attention to its comparative 

 composition with Indian meal, which it most nearly resembles, 

 and in comparison with which its value is decidedly inferior. 

 Th6re is little difference in the feeding effects of sugar and starch; 

 the former contains somewhat more of oxygen, which in some 

 slight degree facilitates its consumption in the respiratory process; 

 but in the same ratio it is deficient in carbon, and lias consequent- 

 ly less of the property of producing fat. 



The respective quantities of oxygen from the air required foi 

 the consumption of 



100 parts of starch are, _.. 118.52
