large improved Yorkshire and Taiiiworth breeds than from the Poland ChinaH or 

 what may be termed the lard types. The cross of the large improved Y^orkshire 

 and Tamworth breeds upon the Poland China sows of the corn-reared types produces 

 animals at once vigorous, shapely, 'growthy,' and relatively more profitable than pigs 

 from the aforementioned sows. During the two years covered by the experiment 

 jxjrk was produced with six lots of pigs with various blood lines subsequent to the 

 weaning jiei-iod at an average cost for food 2.24 cents per pound." 



Molasses as a food for army horses, (i. E. Griffin {Twentieth Centiirti Fanner, 

 190.2, No. 09, p. '^). — The feeding value of molasses was tested with 8 army horses in 

 Porto Rico, this material being fed with chopped grass, in accordance with the local 

 custom. The molasses ration was gradually substituted for the usual ration of oats 

 and hay until the animals were fed on an average 35 lbs. of grass and 14 lbs. of 

 molasses per head daily. "The molasses was diluted with 25 per cent of water and 

 mixed with the chopped grass as far as possiV)le; where all could not be mixed it 

 was dissolved in water and offered as a drink, which was partaken of during the 

 night out of the Inicket left in each manger." The molasses ration was continued 

 for some 5 months. At first all the horses lost weight, l)ut after a time gained in 

 weight from 35 to 68 lbs. The average cost of the grass and molasses ration was 15 

 cts. per day, and that of the hay and oat ration 27 cts. Favorable results were also 

 observed when molasses and grass ,were fed instead of the ordinary ration to several 

 horses which were out of condition. 



From liis tests, the author concludes that 35 lbs. of grass and 13 to 15 l})s. of molasses 

 daily per 1,000 lbs. live weight is sufficient to maintain a horse in good working 

 condition in a climate like that of Porto Rico. Upon this ration the animals tested 

 did more work than on the usual ration, wliile their condition and coat improved; 

 there was less tendency to perspiration, the wind decidedly improved, the urine 

 increased slightly. A tendency to constipation was observed but was readily over- 

 come by feeding bran. Sudden changes from the dry ration to tlie molasses ration 

 did not prove injurious, nor did they cause digestive derangement. A change from 

 the molasses ration to ordinary dry ration should be made gi-adually. The disad- 

 vantages noted were as follows: "Molasses attracts insects, notably flies and ants; it 

 sticks to the animal's coat, smears his face and breast, halter and halter strap, soils 

 the clothing and eijuipment of the men, and causes some trouble and delay in mix- 

 ing it with the grass, which must be cut line." 



Poultry feeding, 11. J. Wheeler (Rhode Island Si a. Bui. S4, jip. lo,5-l67). — The 

 princi})les of poultry feeding are discussed. 



Plump V. shrunken wheat as food for laying hens, M. p]. Jaffa ( California 

 Sta. apt. 1899-1901, jit. 1, j>p. 5G, .57). — Analyses are reported of shrunken andi)lump 

 wheat. On account of its high protein content the author believes the shrunken 

 would prove satisfactory as a food for laying hens.

Soiling crop experiments, C. B. Lane {Neiv Jeri<ey Stas. Bui. 15S, pp. IS, pfe. 4). — 

 This bulletin summarizes the results of experiments during 6 years in regard to pro- 

 viding a uniform supply of succulent food for dairy cows from May 1 to November 1. 

 Data obtained each year have been published from time to time in the reports of the 

 station. The value of different crops for this purpose is di.scussed and methods of 

 culture are given. Alfalfa is considered the most promising crop. During 5 years 

 the herd averaged 21 cows and was fed soiling crops for 6 months and silage for 6 

 months each year. On soiling crops the average production per cow was 3,423 lbs. 

 of milk and 172.7 lbs. of butter, and on silage 3,050 lbs. of milk and 157.4 lbs. of 

 butter.
