SCIENCE AND INDUSTRY.
 Every electric motor manufactory in the United States is said to be crowded to it's utmost capacity to meet the demands for electric power.
 California. it is said now manu- factures nearly all the iron she needs, though only a few years ago she de- pended on the East for her supply.
 -By the new welding process. in which electricity is used, tLe rails of street or steam railways can be welded together it is said, after being placed in position.
 As many as 71z748,854 gallons of malt liquor were consumed in the United States last year. Nearly all of it was produced in the Republic. only 2,300 000 gallons being imported.
 In experiments made in France, where plates of celluloid were used for sheathing ships bottoms instead of copper, it was found that the plates were intact and free from marine growth, which was abundant on parts not protected by the celluloid.
 So thoroughly have electricians experimented that, by little calcula- tion, they can eompute-the number of the ohms and the length of the wire being known-iust how powerful q battery will be needed to produce electrical effects at the further end of the line.
 A single kiln in the secluded town Of San Felipe, in the Mexican state of GuanaXuato, is produced lustred pot tery rivaling in brillianey the Gubbio lustres of the sixteenth century Duf- ing his Mexican to8r of two years ago Charles Dadley Warner found speci- mensof this ware. the making of which had been supposed to be a lost art.
 A volt stands in the scale of clec- tromotiye force where an inch is in the ordinary mode of linear measurement at the base. It may also be described as one of the parts or set5 of which an electric battery is constructed. and consists of plates Of zine, copper and prepared carbon, immersed in a certain number Of acids, eoHtaet with which generates the electricity
 A new wooden pulley has been coatfived, the center being oi east iron and the ria Of wood and t is made in two parts. l. is claimed that by its u5o better belt friction is obtained and q saving in power realized, the spokcs being formed in such manner as te offer but very slight resistance to the motion. By means of d novel and eff. cient paper pushing. keys and set screws are entirely done away. and the grip upon the sbaltins Is said to be perfect.
 Cold storage is great help to egg dealers as it enables the =pefishab.s product to be kept iH q fair condition much longer than &0ald otherwise be the#ea Dakotaaad Minnesota now ship large quantities of eggs to New York and the eggs are stored unti needed ana the older eggs are disposed of first. When the eggs are dceayed there is but one use to make of them manufacturers, who use the yelks il their way of dressing morocco. -Massu chusetts Plowman.
 An interesting variety of carbon ia gas carbon, obtained from the retorts in which Illuminating gas is maaufact. ured. It tresu!ts fGom the burning on of drops of tar upon the interior walls of the retort, and the long continued heating of the crust thus formed. Gas carbon Is very hard, compact and dense; it has a metallic lnstre and con. duets electricity like a metal. On ac. count of its high conducting power, it is employed in the manufacture of gal vanic batteries and for the carbon pencils of the electric lamps.
