steers each received O.IKS 11». of protein per 1.W0 l))s. of live weifjht and j^ained, 

 respectively, at the rates of 0.87 and 1.01 li)s. per head daily. Two Ki'<nips 

 received <loiil)le this protein allowance and the gains were 0.88 and 1.07 lbs., 

 respectively. 



Corn silafje the keystone of economical cattle feeding, .T. H. Skinner and 

 F. (I. Ki.Nci (Imlianit Stti. Bill. 235 (1920), pp. 3-11, fKja. ,3).— The authors sum- 

 marize the steer feetling trials with corn silage conducted at the stJition since 

 the winter of 190G-7. The detailed results have been noted from earlier bulle- 

 tins (E. S. II., 41, p. G8). 



VnU feeding experiment {IndUnin Sfn. Rpt. 1IU9, pp. 26-28, fif/s. 3). — The 

 continuation of experiments with Purdue (home-mixed) calf meal (K. S. R„ 

 36, p. 50;")) is hrietly reported. "The results .securer] from the use of Purdue 

 calf meal in rearinj; younj^ calves are convincing l)eyond a doul)t that it is 

 possible and practical to feed young calves, after they have reached the age of 

 10 to 15 days, without the use* of milk." 



Investigations on the color and markings of cattle, K. Kuipek, .7R. (fJen- 

 cticd [The Ifayiie]. 2 (1920), No. 2, pp. 137-161, fif/n. 5).— Results of experimental 

 cros.ses between Dutch Belted cattle and black and white spotted cattle (Hol- 

 stein markings), made by K. Houwink, are reported and discussed. The FiS 

 were self black. The olT.spring of an Fi bull by spotte<l cows consisted of 27 

 belted, 24 self black, and 8 irregularly si)otted individuals, and a calf that was 

 either sjjotted or self. It is concluded that the factor for the belted pattern 

 and the factor for self color are linked iu such a way that they give the redupli- 

 cation series 1:7:7:1. 



The brindle color in cattle in relation to red, C. Wriedt (Jmir. Genetics, 

 9 (1919), Xo. 1, p. So). — Some data on colors in the Telemark breed of cattle 

 in Norway are cited to show that brindle is definitely dominant to red and is 

 not, as suggested by Wilson (E. S. II., 21, p. 470), the heterozygote between 

 black and red. Among Telemarks blacks are extremely rare while brindles are 

 common, and the matings brindleXbrindle and brlndleXred produce only reils 

 and brindles. 



Xotes on the inheritance of color and markings in pedigree Hereford 

 cattle, F. Pitt (Jovr. Clenetics, 9 (1920), No. 3. pp. 281-302, p?.s'^5).— The author 

 has studied the pedigT(^e records and nn extensive series of photographs of a 

 herd of Hereford cattle l(»cate<l in Shropshire, and presents data as to the 

 inheritance of five pairs of alleloniorphic characters, viz: (1) Excess Avhite, 

 reces.sive to normal Hereford marking, (2) dark (pigmented) neck dominant to 

 the normal white neck, (3) "red eye" (ring of red-colored hairs around eye) 

 dominant to the normal white, (4) "dirty nose" (pigmented rhinarium) domi- 

 nant to clean nose, and (5) pale brown coat color dominant to the darker 

 " claret" color. 



Sheep feeding. — IX, Fattening western Iambs, 1918-19, .T. 11. Skinner 

 aiMl (\ M. Vkstai. (ludiana Sta. liul. 23!, (1919), pp. ,^-i6).— Seven lots of 25 

 lambs and 1 of 23 were fed for 3 months in the winter of 1918-19 i»artly in con- 

 tinuation of the work of the previous year (E. S. II., 41, p. 70) on linnted corn 

 rations and the use of hominy feed, and partly to determine whether oat straw 

 and corn silage could be made as eflicient a roughage as clover hay and corn 

 silage by Increasing the proportion of protein supplement fed with the grain.
