per ton to the fodder is said to improve tlie silage. The size of the stack Is 

 usually from 30 to 50 tons, 40 cu. ft. being considered equivalent to 1 ton. 

 A bottom layer of straw aids in preserving the silage. Success in stacking 

 silage depends largely upon the first layer, which should reach a temperature 

 of 130° F. within 24 to 48 hours after stacking. When this temperature is at- 

 tained layers of from 3 to 6 ft. should be added daily, building the stack to a 

 height of 20 ft. It is then topped with a platform and weighted with earth. 



Mock silage, C. L. Bkach (Vermont 8ta. Bui. 170, pp. 126, 127).— A report of 

 the making of a mock silage from dry corn fodder. Three tons of water were 

 added to S tons of shredded fodder. Five days later 2.5 tons more water were 

 added, in another 3 days 4 tons more, a week later 2 tons, and daily waterings 

 during the following week aggregating about 1,500 lbs. The final product con- 

 tained about 25 per cent of dry matter. It is stated that the silage was relished 

 and proved an efllcient milk producer. 



Cassava bran, a new feeding' stuff, N. Hansson (K. Landtbr. Alcad. Handl. 

 och Tidskr., 52 (1913), No. 5, pp. 370-376; Meddel. Ccntralanst. ForsoJcsv. 

 Jordbruksomrddet, 1913, No. 81, pp. 9). — This is a refuse material obtained in 

 the manufacture of cassava starch, and claimed to be especially adapted for 

 feeding fattening swine. Its composition, as shown by the average of 5 analyses, 

 is as follows : Moisture 13.49, protein 2.6, fat 0.59, carbohydrates 80.94, and 

 ash 2.36 i>er cent. 



A feeding experiment was conducted with 20 pigs, separated into 4 groups, 

 and weighing on an average from 47 to 48 kg. each, in which barley, peas, and 

 cassava bran were compared when fed with whey, boiled Swedish turnips, 

 and peanut cakes. The experiment proper lasted about 12 weeks, the resultant 

 gain in weight being, for the gi'oup fed barley, 0.548 kg. per head daily ; that 

 fed barley and pea meal, 0.574 kg. ; and that fed barley with cassava bran, 0.584 

 kg. One and one-tenth kg. of the cassava bran or 0.95 kg. of pea meal proved 

 equal in feeding value to 1 kg. of barley. The bran was found to have a 

 beneficial influence on the quality of the pork and on the slaughter weight of 

 the swine. 



[Feeding stuffs analyses], B. E. Cuery and T. O. Smith (Neio Hampshire 

 8ta. Bui. 165, pp. 28). — A report is given of 313 analyses of wheat bran, 

 middlings, shorts, red dog flour, other wheat by-products, mixed feeds, calf 

 meals, dried beet pulp, distillers' and brewers' grains, malt sprouts, flaxseed 

 meals, gluten feeds, beef scrap, bone meal, cracked bone, meat meal, cotton- 

 seed meal, hominy feeds, molasses feeds, and poultry mixed feeds, together with 

 the text of the law and notes regarding the inspection. 



Commercial feeding' stuffs, J. L. Hills, C. H. Jones, and C. G. Williamson 

 (Vermont Sta. Bui. 171, pp. l-'i2-165). — Analyses are reported and discussed 

 of nearly 500 samples of cotton-seed meal, linseed meal, distillers' and brewers' 

 dried grains, buckwheat bran, gluten meal and feeds, molasses feeds, ground 

 oats, wheat products, alfalfa meal, corn meal, hominy feed, dried beet pulp, 

 cut clover, meat scrap, and proprietary and other mixed feeds. A discussion 

 of low grade by-products and the mduurial values of feeding stuffs is appended. 



Bran, shorts, and chop-feed, A. McGill and G. H. Clark (Lab. Inland Rev. 

 Dept. Canada Bui. 254, PP- 53). — Analyses are reported of a large number of 

 samples of bran, shorts, middlings, and chop-feed.
