was found to depreciate in value from *l •",:; to J? 1 . 11 , or 20 per cent. In the 

 second year it depredated 50 per cent, its meat value when sold being 55 cts. 



An accurate method for determining' which hens are laying, R. II. YVahk. 

 {Maryland Bta. Bui. 221 (1918), pp. 65-73, figs. 5).— The method described 



consists of examining the hens early in the morning to see whether an unlaid 

 egg can be felt between the pelvic bones. The method was called to the au- 

 thor's attention by a Maryland poultry breeder, and differs in detail from a 

 similar method in use at the Utah Experiment Station (E. S. R., 30, p. 278), 

 with which comparison is made. After the birds became used to the treatment 

 it was found that an experienced man could examine 10 birds a minute when 

 the latter were confined in a small dark compartment. At the Maryland Sta- 

 tion, apparently, the test is expected to be used chiefly as a system of culling. 



The test proved very accurate with a Hock of White Leghorn hens, although 

 in 3 of the IS days of observation, one less egg was gathered than was ex- 

 pected. The test also seemed practical with Barred Plymouth Rocks and White 

 Wyandottes. 



Inspection of commercial feedstuffs, P. H. Smith (Massachusetts Sta. 

 Control srr. Bui. 10 (1918), pp. 3-21, 2// ) .—Report is made of feeding-stuff in- 

 spection in Massachusetts for the year ended August 31, 1018. Complete proxi- 

 mate analyses are given, except in the case of animal by-products. The products 

 analyzed include cottonseed meal, cottonseed feed, linseed meal, corn genu 

 meal, coconut oil meal, peanut oil cake feed, gluten meal and feed, distillers' 

 grains, brewers' grains, yeast and vinegar grains, wheat middlings, red dog 

 flour, shorts, wheat bran, durum wheat middlings and bran, velvet bean feed, 

 rye feed, rye middlings, corn meal, barley meal, ground oats, hominy feed, 

 barley feed, dried beet pulp, oat feed, various stock feeds, molasses feeds, and 

 calf meal, cut clover, alfalfa meal and proprietary mashes and meals for poul- 

 try, meat scrap, bone meal, and fish scrap. 



Commercial feeding stuffs, A. J. Patten et al. (Michigan Sta. Bui. 282 

 (7.''/N>. pp. 3-6S). — Proximate analyses are presented of 010 samples of feeds 

 collected during 101S. These include cottonseed meal, cottonseed feed, linseed 

 meal, distillers' grains (corn), brewers' grains, yeast and vinegar grains, corn 

 gluten feed, corn gluten meal, hominy feed, corn oil cake meal, corn feed meal, 

 alfalfa meals, wheat bran, wheat middlings, barley feed and screenings, rye 

 feed, oat hulls, pea bran, velvet bean meal, buckwheat bran, dried beet pulp, 

 tankage and various proprietary stock feeds, calf meals, and poultry feeds. 



It is stated that 8.3 per cent of samples were below guaranty in protein, 

 7.5 per cent below in fat, and 12.8 per cent above in crude fiber. This is nearly 

 50 per cent better than the results of 1016, the year in which the inspection 

 work was taken over by the experiment station. 



Commercial feeding stuffs, 1917-18, F. D. Fuller (Tc.ras Sta. Bui. 23k 

 (1918). pp. 3-416). — A detailed report is given of analyses completed during 

 the year by the feed control service of the station, arranged alphabetically by 

 towns and showing the names of manufacturers or importers registered in each 

 town. Proximate analyses are given of the following feeding stuffs : Alfalfa 

 meal, barley chop, coconut cake, coconut meal, cold pressed cottonseed, corn 

 bran, corn chop, corn feed meal, cracked cottonseed feed, dried beet pulp, ear 

 corn chop, flaked velvet bean feed, ground cottonseed feed, ground oats, ground
