HOW TO MAKE STEEL FLOAT

Needles Held on Surface of Water by “Tension” Just as Bklp-Jacks Run About on Ponda. Will steel float on water? Ask this question In a crowd and almost everybody will say “no." Then

go ahead and prove that steel will float Take a glass full of water and some fine steel needles, perfectly dry. Lay the needles carefully on the surface of the. water one at a time. If you are careful enough about it they will float. The needleß are held up by the “surface tension” of tbe water, just as are the skip-jaoks that run on the surface of ponds. Juvenile Books a Century Ago. Does the modern child count Mt blessings in the matter of Christmai; books? What would he say if, instead of one of tbe healthy, brightly written stories that now crowd the booksellers' windows, he received a copy of one of the books for juvenlleß In vogue a century ago? The very titles of some of these old volumes would rouße the back of present day youth—‘The Advantages of Education as Elucidated in the History of the Wingfield Family,” Elisabeth Ann Dove’s “Tales of My Pupils, or, an Attempt to Correct Juvenile Errors;” 8. W.’s “A Visit to a Farm; or, an Introduction to Various Subjects Connected With Rural Economy” (this reached a fifth edition in 1811), and Sandham’s "Perambulations of a Bee and a Butterfly, in Which Are Delineated Those Smaller Traits of Character Which Commonly Escape Observation.”—London Chronicle. vWr. ; \ Safety Valve for Vesuvius. An Italian scientist proposed to supply a safety valve for Vesuvius by boring a tunnel in the base of the mountain and letting the iaVa escape Into the sea. His idea Is to bore the tunnel while the crater Is in a state of coma, and he believes that when the volcano beoomes active such a channel would be sufficient to carry away the lava, says Popular Mechanics. His whole proposal, however, is not to let the, lava escape altogether, but to run it Into molds and, make it Into blocks for use in the streets and quays of Naples.
