904 EXPEEIMENT STATION EECORD. 



within a weeli from that time one-half of the hens were laying regularly, while the 

 other lot of Ehode Island Reds were just beginning to molt and the egg i)roduction 

 had dropped down to 2 or 3 eggs per day. Both lots of White Leghorns were a trifle 

 slower in molting than the Rhode If^land Reds, but otherwise the treatment affected 

 them in a similar way." 



For 10 days the dropping boards in the 2 White Leghorn houses were not cleaned. 

 There were comparatively few feathers in the droppings from the lot fed continuously, 

 while a very large number were found in the droppings of the fowls fed by the Van 

 Dreser method. According to the authors' summary — 



"Mature hens which are fed very sparingly foi' alaout 2 weeks and then receive 

 a rich nitrogenous ration molt more rapidly and with more uniformitj^, and enter 

 the cold weather of winter in better condition, than similar fowls fed continually 

 during the molting period on an egg producing ration." 



Commercial feeding stuffs in the Connecticut market, E. H. Jenkins et al. 

 {Connecticut Slate Sta. Bid. 141, pp. 60). — According to the provisions of the State 

 feeding stuff law, analyses are reported of a number of samples of cotton-seed meal; 

 linseed meal, old and new process; bran and middlings from winter and spring 

 wheat; mixed feed from spring and winter wheat, and unclassified; corn meal, glu- 

 ten meals and feeds, hominy feeds; rye bran, rye feed; malt sprouts, brewers' grains; 

 ground oats, oat feed; buckwheat middlings and hulls; peanut bran, broken pea- 

 nuts, distillers' grains, and a number of miscellaneous mixed feeds; proj^rietary 

 feeds; cereal l)reakfast food by-i^roducts; poultry feeds; damaged breakfast foods 

 (offered for sale as cattle feed), and calf meal. According to the authors — 



" The composition of most of the feeds which have guaranties is in substantial 

 agreement with these guaranties. The only evidence of deliberate fraud in the feed 

 market which is shown by the analyses is the mixing of finelj'' ground corn-cob or 

 corn bran with mixed wheat feed, and selling this mixture in packages which do 

 not bear tlie name of the manufacturers nor any statement giving the composition 

 of the mixture." 



The digestil)i]ity of feeding stuffs and some other general tojiics are discussed. 



Slaughtering and meat packing, H. C. McCarty {T'welfih Census United States, 

 Census J!id. 217 , pp. Jfi). — Statistics are reported of the geograjihical distribution, the 

 condition at the present time, and the growth of the slaughtering and packing indus- 

 try. The reports show a capital of $189,198,264 invested, and an annual value of 

 products of $785,562,433. 



Wool manufactures, W. J. Battison {Twelfth Census United States, Census Bui. 

 236, pip. 12.')). — Statistics are given showing the present condition of wool-manufac- 

 turing industries, the amount of imports and exports, the geographical distribution 

 of the mills, the proportional amount of different manufactured products, and related 

 topics. The annual value of the manufactured products is estimated at $392,473,050. 



DAIRY FARMING- DAIRYING. 



Experiments with dairy herd, A. L. ILvecker {Nebraskrc Sta. Bui. 76, pj). 21, 

 jigs. 6). — The herd record (pp. 3-13). — During the 5 years from 1897 to 1901 the dairy 

 herd comprised from 7 to 14 cows each year. The annual i)roduction of each cow is 

 given. The average yields of milk, fat, and estimated butter for the 52 lactation 

 periods reported were, respectively, 5,833.17, 270.7, and 315.82 lbs. One cow, a 

 grade Jersey, produced on an average during the 5 years 7,377.68 lbs. of milk and 

 316.25 lbs. of fat, while another cow of similar breeding but different in form pro- 

 duced only 1,278.76 lbs. of milk and 52.77 lbs. of fat during the one year in the herd. 



Rat4on tests for dairy cows (pp. 14—18). — Twelve cows were divided into 2 ecjual lots 

 and fed experimentally for 2 periods of 6 weeks each. Alfalfa hay was fed ad libitum 

 to lot 1 during the first period and lot 2 during the second period, and wild grass
