Experimental investigations on the inheritance of hyperdactylism of fowls. 

 II The influence of the father, D. Babfurtii {Arch. Entivickl. Mech. Organ., 

 27 {1909), \o. .',, pp. 65S'6B1, pi. i).— A 5-toed Orpington cock was mated with 

 7 hens of 'the same breed. Of the 120 offspring 53, or 42.17 per cent, inherited 

 the extra digit, as contrasted with 52.6 per cent inherited from a hyperdactyl 

 mother (E. S. R., 20, p. 1170). 



Sheep breeding- experiments 1904-1907, D. A. Gilchrist {County Northumb., 

 Ed. Com., Bill. 13, p'lh S-11).— When Oxford Down and Border Leicester rams 

 were mated to half -breed ewes each cross gave about the same number of lambs, 

 but the Oxford Down ram gave slightly better results as far as fat lambs 

 were concerned. On an average of 4 seasons the Border Leicester cross produced 

 much stronger lambs than the Oxford Down cross, as 1.6 per cent of the Border 

 Leicester cross lambs died from weakness as compared with S.6 per cent of th(:> 

 Oxford Down. On the average of 3 seasons the Border Leicester ram produced 

 sheep which were ready for the butcher about 2 months earlier and realized 

 2s. 4d. per head more than the Oxford Down cross. 



Crosses with a Lincoln ram were ready for the butcher at about the same age 

 as the Oxford Down cross, but realized Ss. lOd. a head more. The Border 

 Leicester cross shearlings were fat about 4 months earlier but realized 3s. 5d. 

 a head less than the Lincoln cross shearlings. 



A new breed of ducks {Country Gent., 74 {1909), No. 2953, p. SJ,5, fig. 1).— 

 A new breed of ducks, formerly known as the Campbell duck, but recently 

 named the Khaki, is figured and described. It originated as a cross between 

 the Rouen and Indian Runner ducks. The color is buff, with some of the 

 markings of the Rouen. The females have indistinct pencilling in their plumage. 

 Some of the drakes have a bronze neck and tail. It is claimed that these ducks 

 are good layers as well as first-class table ducks.

 Aires: Govt., 1909, vol. 3, pp. 57-102).— This is a history of the live-stock in- 

 dustry in Argentina from the introduction of horses by Mendoza in 1535 to the 

 present time. 



Statistics of live stock in Argentina in 1908, A. B. Martinez et al. {Censo 

 Agropecuario Nacional la Gatiaderia y la Agricultura en 1908. Buenos Aires: 

 Govt., 1909, vol. 1, pp. XX+434, maps 17). — Complete statistics are given in

DAIRY FARMING— DAIRYING— AGROTECHNY. 



A study of some Connecticut dairy herds, J. M. Truman {Connecticut 

 Storrs Sia. Bui. 57, pp. 287-310). — This bulletin gives in detail the amount and 

 cost of feed, yield of milk, and gross and net income of individual cows of 5 

 Connecticut dairy herds. The results are summarized in the following table, 

 the averages given being for those cows which completed a full year's test in 

 the case of herds 1-4, and for those which completed a nine months' test in 

 the case of herd 5.
