to a variety of mineral substances in order to siijiply, according to the dictates 

 of appetite, any deficiencies in tlie feed. 



Examples are given for calculating rations. 



Spanish peanuts, soy beans, and skim milk as feeds supplementary to corn, 

 P. X. Flint ( dcorfjia Hta. BnJ. HI, pp. 3-10, fic/s. .',). — This is a report of a feed- 

 ing experiment in utilizing home-grown feeds for pigs. The pigs varied in age 

 from 3 to 4 months and had an average weight of 7G.9 lbs. The feeds were 

 rated as follows: Shelled corn 94 ets. per bushel, shorts $1.87 per hundred- 

 weight, skim milk 20 cts. per hundredweight, soy beans .$2.38 per acre net cost, 

 and Spanish peanuts $3.38 per acre net cost. 



A lot of 3 pigs fed shelled corn and shorts 1 : 1 for 31 days, and then corn 

 alone for 48 days, made an avei-age daily gain of 0.71 lb. per head at a cost of 

 S.3 cts per pound. The corresponding figures for a lot of 6 pigs fed shelled corn 

 and skim milk was 0.96 lb., at a cost of 6.S cts. On a shelled corn ;md fresh 

 soy beans ration there was an average daily gain per head of 0.7 lb., at a cost 

 of 5.0 cts. per pound, and on a ration of shelled corn and fresh Spanish peanuts 

 the corresponding values were 0.9 lb., and 4.6 cts. 



Data are also given on the cost of growing soy beans and Spanish peanuts. 



Yeast as a feeding stuff (Wchnschr. Bran., 21 {1910), No. 2, p. 18).— Two 

 pigs weighing al)out 22 lbs. each were fed a ration of potatoes, ground barley, 

 and yeast. The amount of yeast fed daily to each animal varied from 1 liter at 

 the beginning to over 10 liters at the close of the trial. It was apparently rel- 

 ished by the pigs. At the end of 5 months the average weight was 190 lbs. 

 each. The average dressed weight after slaughtering was 83 per cent of the 

 live weight. 



Report of the departmental committee on poultry breeding in Scotland, 

 J. Murray et al. (Edinhiinjii : Govt., 1909, pp. IV+IS). — This report is the 

 result of an inquiry upon the methods commonly followed in the highlands and 

 islands of Scotland in the breeding and Ivceping of poultry and the sale of 

 poultry and eggs, and especially into the results of the efforts of the Congested 

 Districts Board to promote this industry and to suggest how it may be developed 

 and improved. 



Minutes of evidence taken before the departmental committee on poultry 

 breeding in Scotland {Edinburgh: Govt., 1909, pp. XXVIII+I4S). — This con- 

 tains the statements made by men engaged in the poultry business in Scotland 

 and forms the basis of the I'eport noted above. 



Poultry breeding, T. Huperz {Die GeflugcJzucht. Ncudnmm, 1901, 3. ed., 

 rev. and cnl., pp. VIII+350, pi. 1, figs. 18). — The third revised and enlarged 

 edition of this practical book on the breeding, feeding, and rearing of fowls, 

 turkeys, guineas, ducks, geese, and pigeons. 



The dollar hen, M. M. Hastings {Neio York, 1909, pp. 211, figs. //).— This 

 book, according to the author, was written " for the purpose of assisting in 

 placing the poultry business on a sound scientific and economic basis." The 

 topics treated are incubation, feeding, management of poultry, marketing of 

 eggs, and other phases of ixjultry production upon which the financial success of 

 the business depends. 



The author makes statements regarding poultry work at the Illinois Station, 

 and gives an alleged quotation from its publications which turns out to have no 

 basis whatever in fact. That station has not carried on any poultry woi-k or 

 published anything on the subject, and the hypothetical experiment described is 

 of such a character as to be an unjustified refiection on experiments in that 

 line.
