' " . ■ .Myopia, wlthiill Itsirttendant-annoynnces, Is Increasing in tho public schools both here and abroad. Intensity ol. application to work under, the stimulus of competition is ono of the principal causes of short-sight¬ edness among children. 'Imperfectly light¬ ed schoolrooms Is another. ' ' ^, Iii curious contrast with prevalent notions about the Arctic regions arc tlio statistics of trade between the four ports of Norwegian Flninark and the Russian ports of the White sea, especially Archangel* lu 1841 470 ves¬ sels, employing Over 2,000 men, visited the 'Flninark ports, and In 1882 a still larger number, bringing goods, chiefly tin) pro¬ ducts of the-rich llsnerles of the'Whlte sea, to tlie amount of more than $700,000, and re¬ ceiving cargoes for Russia ot nearly equal value. ' Tho velocltv.of the wind 'within the vor¬ tex of a tornado Is, according to a report of ' the United States signal Bervlce, variously estimated at from 70 to 800. miles an hour, tho nverago being 392 miles. It would bo Interesting to know in .what wiiy these"ve¬ locities were estimated, An avcraguof 302 miles certainly indicates supposed accuracy, but they Were not measured, and a velocity of'800 miles an hour, eorrespondlngon the lowest basis ol calculation to a pressure of 1,000 pounds to the square loot, seems almost incredible. There is, liowevor, no reason to doubt, that over a vory limited areatho ve¬ locity and pressure ot the wind In theso tor¬ nadoes or whirlwinds are very much greater than any tbiit havo been accurately meas¬ ured. The shipbuilding trade on tho Clyde con¬ tinues brisk, although not so many vessels are on the Btocks as formerly, Recent sta¬ tistics show that for the month of Mayjll vessels of 35,435 tons wero launched, being an increase of 3,104 tons,over tlio corre¬ sponding month last year, but 270 tons un¬ der that of May, 1881. In the live mouths thoro Is an increase of 24,762 tons over the output for the same period last year, and of 08,100 tons over that of 1870. As contrasted with 1873, which was then considered a pe¬ riod of. extraordinary briskness, tills year surpasses that by 30,500 tons. Of tho ves¬ sels launched there are 24 steamers of 31,005. tons and 7 sailing vessels of 4,430 tons. Tho most Important vessels launched were the City of Chicago, an Inmim Liner nf 8,000 tons, and a Clan Liner, the Clan Mucphcr- soii, of 3,880 tons. The average size (if the vessels launched was 1,143 tons for the mouth, and 1,320 tons for tlio five months, as against 1,1,55 tons and 1,307 tons respec¬ tively, in 1882, and 1,015 tons and 1,005 tons In 1873, There are 142 vessel) at present in course of construction, being a decrease of 8 as-contrasted with the number building at the end of April, and 12 less time at the close ot May 1882. A prlvato dispatch from Detroit says tl « schooner Hercules, sunk by the propeller Clarion of the Anchor Line, was InBUrod fur $2,000 In the Thames and Mersey. The Clar¬ ion Is ireld responsible tor tho disaster. The agents t.f^Uie Anchor Line have made a proposition for settlement of tlie claim, but It Is not yet accepted by the owner of the Hercules. __________'_^__________ GLOBE IRON IRKS Iron Shipbuilders, MaeMiiists, Fouuflers and.
