SCIENCE AND INDUSTRY

There are in Paris l,ai6 factories. The world's output of coal in 1900 was 767,636,000 tons. A large factory in Jena, Germany, utilizes- its surplus hot water in such a way as to afford the laborers nearly a thousand hatha per week. In aome German, cities it is customary to fee street car conductors, who are thus enabled to add from four to six dollars a month to their income. The richest farm in the world is an acre worth $288,000inthehea-TtofNew York* ultra-fashionable district, between West End avenue and Riverside drive. It is tilled regularly and the prbd.uce is sold at the nearest market. During the civil war the site was covered by a- government recruiting station. * ' A research steamer belonging to the Norwegian government recently carried on the North sea some experimental fishings which yielded important results. In three days 117 halibut and 300 large cod were caught at a depth of 200 fathoms, thus proving the existence of large quantities of these fishes at a time of the- year when they are not to be found on. the coast of Norway. Many people imagine that the incandescent electric light gives out little .or no heat, but it is found that of the energy consumed only six per cent, is converted into light, while 95 per cent, goes into heat; A lamp ifnmersed in water will bring the water to a boil, and. many cases- of fire have been caused by carelessness in letting inflammable substance© rest in Contact with the lamp. Prof. James Dew&r, president of the annual meeting- of the British Association for the Advancement of Rcience at Belfast, has pointed out in the boldest language that while Englishmen have repeatedly discovered- scientific principle* and laws of great importance, the Germans and Arre v icans have been making the practical a ppli-"-yions of them, leaving England behind in reaping the advantages.
