LEFT DAISY 247 D'ALEMBERT shire and Jersey hold the first place for dairy purposes, the first on account of the large yield which they give on com- paratively poor feeding, the second for the richness of their milk. In the manage- ment of a dairy cleanliness is of the ut- most importance, as no substance more easily receives and retains the odors and taste of putrescent matter than milk. No food, either vegetable or animal, should be allowed to enter the milk -house. A good mode of purifying the atmosphere of a milk-house is to dip clothes in a so- lution of chloride of lime and then hang them up on cords stretching from one corner to the other. In a similar way, too, the temperature of the room may be kept low during hot weather. The milk- room, therefore, should be built in such a manner as to be most easily cleaned and kept clean. The floor should be of smooth flagstones carefully jointed and dressed. It should have a slight slope toward the wall, where a channel is formed to convey all water and spilled liquid to a drain. All cornices and moldings, or any pro- jections or cavities where dust or dirt can lodge, should be as far as possible avoided. The practice of making a larder of a portion of the milk-house, or of hav- ing a number of cheeses drying on the shelves, is much to be reprehended. Spilled milk should never be allowed to remain an instant longer than is neces- sary for its removal. The liberal use of water (cold in summer and warm in winter) is always to be commended; a little common washing-soda dissolved in the water will be found useful in destroy- ing any taint of sourness the milk-dishes may have acquired. The best dishes for milk are made either of glass, tin, tinned- iron, or well-glazed earthenware. Wood is objectionable because it is difficult to keep the dishes clean, and lead and zinc are liable to corrosion or decomposition from the acid of the milk. See also But- ter; Cheese. DAISY, the common name of the well- known plants and flowers of the genus Bellis, especially B. perennis. The French call the daisy "Marguerite," from the Greek word inargarita=a pearl. Though daisies are very common in many parts of the world, they are not univer- sally distributed; for instance, the trav- eler may wander over hundreds of miles in the Indian Empire without seing one solitary daisy. DAKIN'S SOLUTION, a preparation of sodium hypochlorite, containing boric acid. It is prepared by treating a solu- tion of chlorinated lime with sodium car- bonate, permitting the precipitated cal- cium carbonate to settle, syphoning oft the clear liquor and neutralizing with boric acid. The resulting liquid is used as an antiseptic and came into promi- nence during the World War, when it was employed in the French military hos- pitals for irrigating wounds. The prep- aration was discovered by Berthollet in 1788, but was not commonly used until it was reintroduced by Doctor D. H. Dakin of New York, while he was serv- ing as bacteriologist in France. The anti- septic action of the solution is one of oxi- dation, brought about either by the de- composition of the hypochlorite with formation of oxygen, or indirectly through the formation of chloroamide groups. DAKOTA. See North Dakota; South Dakota. DAKOTA, or DAKOTAH. See SlOUX. DAKOTA WESLEYAN UNIVER- SITY, an institution for higher educa- tion, founded at Mitchell, S. D., under the auspices of the Methodist Episcopal Church. It includes a College of Liberal Arts, and schools of commerce, education, elocution, and art. In 1919 there were 32 instructors and 538 students. Presi- dent, W. D. Schermerhorn, S. T. B. D'ALBERT, EUGEN, an Anglo-G«r- man pianist and composer; born in Glas- gow, Scotland, April 10, 1864. He studied at Weimar under Liszt and be- came famous as a performer when only 18 years of age. He made numerous suc- cessful concert tours in the United States and throughout Europe, and was espe- cially famous for his interpretations of Bach and Beethoven. He was consid- ered one of the finest technicians and his intellectuality and fire placed him in the foremost rank of pianists. His composi- tions included many pieces for the piano, numerous songs, and several operas, of which latter "Im Tiefland" was per- formed in New York in 1908. DALECARLIA, or DALARNE, a tract in Sweden. The name, meaning "valley^ land," is kept alive in the minds of the inhabitants by the noble struggles which the Dalecarlians, its inhabitants, made to establish and maintain the independence of the country. D'ALEMBERT, JEAN LE ROND (da- lon-bar'), a French mathematician and encyclopaedist; born in Paris, Nov. 16, 1717; was the natural son of Madame de Tencin and the Chevalier Destouches; and was brought up by the wife of a poor glazier; but his father, without publicly acknowledging the paternity, secured to him an allowance of 1,200 francs a year. At 12 the boy entered the College Ma-
