Prehistoric cattle skulls in the museum at Schwerin, and their significance 

 to the history of cattle breeding in Mecklenburg, W. Zengel (Die ptahis- 

 torischen Rinderschadel im 3Ivseum zu Schwerin und deren Bedeutung filr die 

 Qeschichte der mecklenburgisclien Rindviehzucht. Inaua. Diss., Univ. Bern, 

 1910, pp. 20; Arch. AnthropoL, n. set'., 9 (1910), No. 2-It, pp. 159-178).— This 

 contains descriptions and measurements of skulls, which are identified as Bos 

 primigenius and B. brachyceros with the exception of 2 intermediate tji>es 

 which the author thinlis are the result of a cross of primigenius and brachy- 

 ceros. A comparison with otlier specimens leads to the conclusion that Meck- 

 lenburg cattle, like other lowland breeds, had their origin in the old red cattle.

DAIRY FARMING— LAIRYINa. 



Eour systems of dairy farming and the profit on each, W. J. Frasee and 

 R. E. Brand (Illinois Sta. Circ. 151, pp. 2.'f). — This circular explains and com- 

 pares 4 different systems of cropping for a 160-acre dairy farm, showing the 

 differences due to kinds of crops and their adaptability to the feeding of dairy 

 cows. 



The results are shown in the following table :

 dairy farmer in southwestern Missouri. 



Feeding dairy cows, C. C. Hayden {Illinois Sta. Circ. 152, pp. 31). — This 

 circular discusses in a popular way the composition and digestibility of both 

 homegrown and purchased feeds, the effects of different feeds on the animal, 

 the summer soiling system, and gives directions for balancing rations. A 

 number of sample rations for dairy cows are suggested. 



Comparative feeding experiments with milch cows in relation to the 

 effect of rice feed meal, sesame cake, and dried brewers' grains, V. Renner 

 {Fiihling's Landic. Ztg., 60 (1911), No. 15, pp. 5i. 5-5.38). —The author reports 

 experiments in which a ration containing dried brewers' grains gave a larger 

 yield of milk and a higher percentage of fat than rations containing sesame 

 cake and rice feed meal. 



The effect of a change of feed on the composition of cow's milk, with
