In Korea, widows never remarry. Even though they have been married only a month, they must not take a second husband. The visitors at the Panama-Pacific Exposition are not to be annoyed by any realization of the flight of time. Clocks are not to enter into the architecture of any of the buildings. Rare Gift for Fatherland. Showing a love of country that could not be more self-sacrificing, Carl Barwieck, an aged resident of Davenport, Iowa, has given to the German war relief fund committee his most treasured family heirloom, a rare German Bible, 311 years old. The book has been in the possession of the Barwieck family for over 300 years. It was printed in Wittenberg in 1603 by Lorenz Seuberlich. “I haven’t anything else to give. Maybe you can sell this for something and get money for the fatherland that way,” said Barwieck, when he produced the old heirloom. His gift was accepted. It is expected to bring several hundred dollars. Wealthy Germans here are planning to buy it and give it to the Academy of Sciences. Various Uses for Quicksilver. Quicksilver, according to the United States Geological Survey, is being used for many new purposes. It is used mainly in the manufacture of fulminate for explosive caps, of drugs, of electric appliances and scientific apparatus, and in the recovery of precious metals, especially gold, by amalgamation. One use in the United States, and possibly elsewhere, is the coating of ships’ bottoms with a paint containing quicksilver to prevent organic growth. Mercuric oxide--red oxide of mercury--is the active poison in antifouling paint successfully used on ships’ bottoms. The metal appears to be but little employed in silvering mirrors, as nitrate of silver is now chiefly used for the purpose. Increasing use of quicksilver is probably to be expected in the manufacture of electrical appliances and fulminates and possibly of paints for protective coatings on metals. The demand for quicksilver for amalgamating gold and silver has greatly decreased, as is well known, with the decreased supply of free milling ores and the increased application of cyanidation to gold and silver ores. Industrial chemistry and inventive genius are to be looked to for increasing the demand. The quicksilver production of the world during 1913 is estimated at 4,171 metric tons, against 4,262 tons in 1912 and 4,083 tons in 1911. Spain last year headed the countries of production with 1,490 tons. The United States produced only 688 tons. The other producing countries were Austria-Hungary, 855 tons; Italy, 988 tons; Mexico and others, 150 tons. Navy Man Bars “Tipperary.” No longer will the song “Tipperary” be heard at the United States Naval Training Station, at Newport, R. I., because Lieutenant Commander Frank Taylor Evans, executive officer, has decided that for navy men to sing it is a violation of President Wilson’s neutrality order.
