Growing draft colts, C. W. McCampbell (Kansas Sta. Rpt. 1915, pp. o.J-€.9, 

 fiffs. 16). — An experiment was started in January, 1913, the objects of which 

 were to determine (1) whether the good draft colts can be grown without the 

 use of oats, (2) the cost of developing draft colts under ordinary Kansas con- 

 ditions, and (3) the type of colt which usually develops into the largest horse. 



The results of the experiment show that " the colts receiving a grain ration 

 of 70 per cent of corn, 25 per cent of bran, and 5 per cent of oil meal made a 

 daily growth of 1.023 lbs. during the entire period of 720 days, while the colts 

 receiving oats made a daily growth of only 0.926 lb. Each pound of growth 

 during the entire period made by the colts receiving corn, bran, and oil meal 

 <c*ost 15.04 cts., while each pound made by the colts receiving oats cost 18.6 cts. 



*' The colts made more rapid growth during the first year after weaning 

 than during the second year. The first year's daily growth averaged 1.285 

 lbs. and the second year's daily growth 0.7 lb. Although the total cost of 

 feeds consumed during the first year was greater than that during the second 

 year, the growth was cheaper. The average cost of each pound of growth 

 during the first year was 14.2 cts., and during the second year 23 cts. 



" The average total cost of developing the grade colts from the time they 

 were approximately eight months old until they were ready to work (2.5 years) 

 was $123.37. The cost of raising a draft colt to the age of eight months is 

 about $50, making the total cost (including the labor) imtil the colt is ready 

 t.) work approximately .S175, imder conditions and prices similar to those of 

 1913-1914. 



" The colts showing considerable bone and stretch at weaning time developed 

 into the largest horses. The plump, mature-looking weanlings are still plump 

 little horses." 



Philippine horses, D. B. Mackik [Jour. Heredity, 7 {1916), Ko. S, pp. 37S- 

 8S2, figs. ^). — The author maintains that the Philippine horse is not, as popu- 

 larly supposed, a descendant of horses brought to the islands from Mexico and 

 Spain by the Spaniards, but that the bulk of the animals brought in by the 

 early colonists were Chinese. It is shown that horses existed in parts of the 

 archipelago prior to the Spanish conquest, and the ancestry of these is traced 

 to Malaysia. In addition to China other channels hitherto almost unknown 

 have poured equine blood into the Philippines, so that the horses of the islands 

 to-day contain large or small amounts of characters from Chinese, Japanese, 

 Mexican (including various races entering into the race so designated), Persian, 

 Indian, and Sumatran sources. 



[Poultry investig'ations], J. E. Dougheety {California Sta. Rpt. 1916, p. 

 58). — Continuing experiments with high-protein animal and vegetable feeds 

 (E. S. R., 34, p. 268), the results to date indicate that it makes little difference 

 v.hat kinds of such feeds are fed so long as the ration contains some animal 

 feed, has an approximately correct nutritive ratio, and contains feeds suitable 

 to poultry. 



It was founci to be economical to use some animal feed in the ration, but 

 mashes containing as low as 7.7 per cent meat scrap gave us good results as 

 those containing much higher percentages. Where fowls had free access at all 

 times to hoppers of meat scrap and soy bean meal in addition to the basic 

 mash, they ate 10.55 lbs. of meat scrap and 12.7 lbs. of soy-bean meal per hen 

 Iter year, as compared with 1.8 to 3.G lbs. of soy-bean meal and meat scrap, 

 respectively, in other pens where the animal and vegetable high-protein feeds
