76 EXPERIMENT STATION KECOKD, 



the iudustry, wliicii prosiierod I'ur ti time. Quite recently moro interest hna 

 been taken. Many European and Asiatic breeds have been introduced, but not 

 enough eggs are produced to supply the home demand. The number of fowls 

 in IDOG was 10,248,410, tlie number of ducks 2n!).219, turkeys 8,18S, ajid geese 

 0,041. The number of eggs i)roduced in 1007 was 099,404,137. 



Preserving' egg's, A. E. Vinson (Arhona .SV«. JiuL GO, pp. y/3/-.'/3.?).— Methods 

 of preserving eggs by means of limewater and water glass are described. 



Snail gardens, D. Geyer {Sci. At)in: Slip., 6'.S {J 900), Xo. J75',, p. !)!)).— An 

 account of the edible snail industry of France, Wurttemberg, and Baden, which 

 seems to be of growing importance. Many of the snail farmers are beginners 

 and their methods of caring for the animals, described in detail, show little 

 evidence of a knowledge of the real needs. Most of the snails are sent to the 

 I'aris market, which opens the first of November. 



"The great French demand for snails has led to the invention of imitations. 

 The snail farmers collect the empty shells that have acciunulated during the 

 summer, wash them and sell them for about 25 cts. per thousand. Tlie shells 

 are sent to Paris, where they are filled with a mixture of snail flesh, liver, butter, 

 and herbs." 



DAIRY FARMING— DAIRYING. 



The substitution of roots for concentrated foods in rations for milk pro- 

 duction, E. .S. Savage (Xcw York CornvU St a. Bill. 268, pp. .'/.JJ-//87', fi<js. 0). — 

 The object of these feeding trials was to compare the value of the dry matter 

 in mangels with that in silage and in grain, and they were conducted in a man- 

 ner similar to that of a Danish feeding trial previously reported (E. S. R.. 10, 

 p. 900). There were four groups of 5 cows each. The feeding period lasted 

 weeks, but the data do not include the first week of each period. The mangels 

 were estimated to be worth $4.50 per ton and the silage $2.25. 



In the experiments of 1007-S ration 1 consisted of hay. silage. Ajax flakes, 

 corn meal, wheat bran, and cotton-seed meal. In ration 2, 2 lbs. of mangels 

 were substituted for each pound of silage. In ration 3, mangels were substi- 

 tuted for one-half the grain ration. In 1908-9 the rations were similar, but the 

 grain ration consisted of Ajax flakes, buckwheat middlings, corn meal, wheat 

 bran, and oil meal. 



For the 2 years the total dry matter required for the production of 1 lb. of 

 milk fat on the hay, grain, and silage ration was 22.34 lbs., on the hay, grain, 

 and mangels ration 20.93 lbs., and on the ration whei-ein one-half of the grain 

 was substituted for silage and mangels 22.02 lbs. The average cost of 1 lb. of 

 milk fat on these rations was 20.7 cts., 27.4 cts., and 20.7 cts., respectively. 



No conclusions were drawn as to the effect of the dift'erent rations on the 

 live weight of the cows. One lb. of dry matter in mangels was considered 

 equal to 1 11). of dry matter in grain, which agrees wnth the Danish experiment, 

 and a little more than equal to 1 lb. of dry matter in silage, but the cost of 

 ration 2 was considered too high to be economical. 



Estimating the average price of commercial feeding stale's at $30 per ton, 

 "it would seem to be a safe assumption tliat farmers can raise mangels for $4 

 per ton and thus reduce their feed bill very materially, by the judicious use of 

 mangels to replace one-half of the grain ordinarily fed in the ration." 



The effect of raw potatoes, potato flakes, and potato chips on milk pro- 

 duction, J. Hansen et al. (Fii Ming's Landic. Zfrj., 58 (lilOf)), No. 16, pp. .'>11- 

 ggj), — The object of these trials was to determine the best form in which to 

 feed potatoes to milch cows. The basal ration consisted of 8 kg. of hay, 3 kg. 

 of oat chaff, 3 kg. of brewers' grains molasses, and 5 kg. of peanut cake per 1,000
