and therefore valued at £4 lOs. per ton, = 10s, per ton in 

 the natural state. 



From the following tabular statement, it will be found 

 that in wheat-straw, for which I pay 35s. per ton, I obtain 

 for Is. 2Jd. '50 oil and 321bs. starch, or (the starch reduced 

 as oil) IS^lbs., available for the production of fat or for 

 respiration. I know no other material from which I can 

 derive, by purchase, an equal amount of this element of 

 food at 80 low a price. The value of straw calculated as 

 manure ia 9s. 7d. per ton. 



Swedish turnips, at 10s. por ton, give of oil_ and starch 

 reduced as oil 35Jbs. for 2s. 2jd. In comparative nutritive 

 value, lOs. per ton is much too low an estimate. 



Oilcake, beans, Indian-meal, and locusl-ieans have been 

 taken at the same price, viz., Id. per lb., or £9 6s. 8d. per 

 ton ; any variation in their relative market value will alter 

 the figures here given in the same proportiou. Of the four, 

 oilcake is found to be the cheapest at the same price,beinf!; 

 much preferable to beans for fattening. The locust or 

 carob bean, at the same price, is much the dearest. In 

 these computations the albuminous matter is calculated only 

 on its value as manure. When assimilated in flesh or 

 fibrlne it has a higher value in proportion to its weight than 

 fat, and it is on the due apportionment of materials rich in 

 albuminous matter that our success in feeding cattle with 

 profit in great measure depends. For the purpose of 

 acquiring more precise information, I availed myself of the 

 assistance of Professor Way, who selected for analysis a 

 piece oi heei particularly lean, and reported it to consist of — 



Water 53.81 



Fat 3-10 



Albuminous matter 24 06 



Other substances 19'3 



100 00 



This material, though of its kind particularly rich in 

 nitrogen, is hot worth more as manure than 2s. 6^d. per 

 100 lbs., or less than one-twentieth of its value as food. 



These investigations, which have more or less occupied 

 my attention for several years, have changed considerably 

 my mode of treatment for fattening. I am satisfied that 

 the most 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, lean and oat- 

 stravi and sltells of oals in equal proportions, with a limited 

 supply of turnips, never exceeding 60 lbs. per d.ay to each, 

 and the following extra food; — 



3 lbs. of rape cake. . "j 



I lb. malt combs >steamed together with the straw.
