The Cape horse: Its origin, breeding, and development in the Union of 

 South Africa, P. J. van dee Schreudeb {Thesis, Cornell Univ., 1915, pp. 122). ~ 

 The author reviews the history of horse breeding in South Africa and tells of 

 the development of the Cape horse, which, although not recognized as a breed 

 in itself, is a type of horse particularly adapted to the needs of that country. 

 This horse gained considerable fame as a remount in the British army. The 

 Cape horse owes his best qualities to Arabian and Thorouglibred stock. It is 

 thought that with intelligent grading and selection and an efficient government 

 control South Africa will be able to put in the market a horse equal to the best 

 of any country.

 horse. 



[Poultry investigations], J. E. Dougherty {California Sta. Rpt. 1915, pp. 

 37, 38). — Tests indicate that the best average temperature for an incubator is 

 102° F. when the bulb of the thermometer is on a level with the top and touch- 

 ing a fertile egg. If, however, the thermometer is above and not touching the 

 eggs, the incubator should be starte<l at a fairly high temi^erature and this 

 temperature gradually lowere<l as the hatch progresses. 



A check pen of 50 2- and 3-year-old hens without high protein feed laid 102.1 

 eggs per hen during the year. Hens of similar character and fed high protein 

 in addition gave the following number of eggs per hen per year : On soy bean 

 meal, 104.9 ; meat scrap, 129.7 ; fish scrap, 131.7. When properly fed, fish scrap 

 did not in any way taint the eggs laid. 



Five pens of 33 hens each were fed a grain mixture consisting of whole wheat. 

 whole barley, and cracked corn or whole Egjptian corn 150:100:50, also a 

 dry mash consisting of bran, short.s, charcoal, and salt 50:50:5:1, to which 

 was added either 30 parts of meat scrap alone or 30 parts of a high protein 

 ration consisting of a combination of meat scrap with soy bean meal or linseeil 

 meal. The average amount consumed per hen per year in the five lots was 49.5 

 lbs. of grain and 23.5 lbs. of dry mash. The average number of eggs laid per hen 

 was 142. The average cost per dozen eggs of grain and mash consumed was 10.5 

 cts. In this trial no advantage was found in a mixture of vegetable and animal 

 protein over feeding animal protein alone. Buttermilk at 20 cents per 10<^> lbs. 

 was found to be a satisfactory and economical substitute for meat scrap at $3.25 

 per 100 lbs.

 487). — The author reviews the experimental work of geneticists during the last 

 15 years, it being pointed out that, while the work has shown the mode of in- 

 heritance of many characters, it has not materially modified practical methods 

 of commercial breeders. 



A hen that crowed {Jour. Heredity, 6 {1915), No. 11, p. .'f82. fig. 1). — A 

 description is given of a Buff Orpington hen, hatched at the experimental farm
