Annual report of tho experiment station for cheese making at Lodi, 1898 

 {A)ui. J\. Sta-. Sper. Cascif. Lud'i, 1S90, pp. lOS). — The lines uf investigation reported 

 upon include the manufacture of several kinds of cheese, the influence of light on 

 the souring of milk, the yield of cheese as affected by the use of soluble lime salts, 

 a chemical study of the alluvial soils of Lodi, and the composition of various fl<jurs 

 used in brea<l making.

Coating: cheese with paraffin to prevent mold, J. W. Decker ( TF/.scovw/h Sta. 

 Rpt. 1899, pp. 153,154, fig. 1). — A number of trials of coating cheeses of different 

 ages with paraffin were made by the author. When properly done the coating was 

 a complete protection against the growth of mold. AVhen the cheese was not care- 

 fully handled the paralfin would break away froni the cheese and mold would grow 

 beneath it. The coating of new cheese was thought to impair the flavor, while the 

 coating of cheese 3 months old or older seemed to cause no injury in flavor. AVhen 

 cheese had been covered with a double bandage and 2)aratfined, the outer bandage 

 could be stripped off, leaving a fairly Ijright cheese. The cost of coating a 10-p<jund 

 cheese was /^ of a cent.

Danish butter exports, 1898-99, B. Boggild {Tidsukr.Laudbkuii., 1899, Xo. 12, 

 pp. 540-548). — The exports of butter during the year October 1, 1898, to September

 avoirdujiois) . The imports during the same period aggregated 34,289,831 1V)S., mak- 

 ing the net exports 110,079,103 lbs. 16,752,853 lbs. of butter was imported from 

 Sweden, and 15,170,051 lbs. from Russia (Finland). About 3,500,000 lbs. of the 

 butter exported was canne<l. The average price received for the export butter dur- 

 ing the year was 25.8 cts. per pound Danish (23.5 cents per pound avoirdupois). —

Denmark's production of milk and butter, 1897, B. Boggild ( Ugeskr. Landm., 

 45 {1899), Xo. 47, pp. 585-587). — The author calculates on the basis of the latest 

 official statistics that the total i:)roduction of butter in Denmark in 1896 was about 

 129,030,000 lbs. Danish, and the total milk production, 4,502,780,000 lbs. The 1,145 

 cooperative and proprietary creameries in the country in 1897 made 116,126,000 lbs. 

 butter and 19,048,000 lbs. (skim-milk) cheese, the average value received for the 

 products at the factory being 23.9 cts. and 3.5 cts., respectively, per jiound. The 

 number of milch cows in the country, according to the census of 1898, Avas

A new Belgian butyrometer, A. Theunis {Ind. LalL, 25 {1900), Ao.s. 21, pp. 

 161, 162; 22, pp. 169-171, figs. 3; Rev. Gen. Agron., 9 {1900), Xo. 2, pp. 50-60, figs. 

 3). — A new form of centrifugal fat tester devised by Mercier is figured and described. 

 The test bottle is provided with a thistle tube through which the milk and the amyl 

 alcohol and sulphuric acid used in the test are introduced. In comparison Mith the 

 Gerber method the test gave closely corresponding results. 



A composite milk-sampling- pipette, J. W. Decker ( Wiscoiisiii Sta. Rpt. 1899, 

 pji. 155, 156, fig. 1). — A pipette designed by the author for taking composite milk 

 samples is essentially a glass tube 5 in. in diameter and about 12 in. long, graduated 

 in i in. spaces, the ends of the tube being somewhat constricted. In using the 

 pipette a sample of milk is taken of as many spaces in the tul)e as there are pounds 

 of milk to be sampled. The individual samples are then in i)roportion to the yields
