l By measuring the heat received from | the sun on certain portion of the earth's surface a scientist has esi-
 mated the heat radiated from the sun. i He announces that the temperature Of that glowing ball is 11,250 degrees | Fahrenheit, which is eight times as far removed from the freezing point as is bright red surface.
 One of the characteristics of ether waves, such as those of light and heat l is that they produce a distinct press ure in the direction they travel. In the case of the earth this outward pressure from the sun is said to be 10000 tons, but this is a mere triie compared with the vast gravitadonal attraction toward the sun.
 A health resort in Lapland is re ported by the British Medical Journal as due to the belief that there are great advantages possessed by Arctic climates in the summer months. Be- fore long summer resorts will be de- veloped In many northern lands which used to be thought e-bound and in hospitable all the year round. The new sanatorium is to be erected on the shores of Lake Torne. a beautiful sheet of water at Wassijaure, near the terminus of the Ofote Railroad. There Is a small settlement at Wassijaure, but otherwise there is no sign of man except during the occasional passage of a few Laplanders with their rein deer.
 Inventors have from time to time tried to devise a form of oar which would enable the rowers of boat to sit facing the bow, instead of the stern. The advantage of such a position Is manifest, but 1t has always been found that greater power of stroke Is ob- tained with the old form of oar. Just at present attention has been drawn in France to a so-called "artculated oar," which permits the rower to face for ward, and which partially solves the problem, at least where no great force of propulsion is needed. The con- struction is very simple. The oar is divided at the oar-lock by toothed sectors, which engage one another like ratchet wheels, so that pull on the inner arm of the oar causes the outer arm, carrying the blade, to move in the opposite direction.
 That the great treeless or forest main in their present condition is the belief of R. s. Kellogg, of the Bureau of Forestry, who, as the result of year or two of careful investigation, says that whatever may be the req sons for the absence of natural for ests on the great plains, close study of established plantations proves that, with an intelligent selection of species and proper care, planted trees can, to a considerable extent, be made to SUD- ply the deficiency. Among the trees suitable for this purpose are the honey locust, the osage orange, the green ash, the red cedar. the white elm, the Scotch and the Austrian pine, the black locust, the black walnut. the sill yer maple, the catapla, the cotton wood and the box elder.
 Sir Oliver Lodge, who some time ago invented an electrical apparatus for dissipating fog by means of electrical currents radiated into the atmosphere, Is convinced that the limita tions of his invention will not allow 1t to be used in clearing great areas of fog as yet, but he thinks that it has practical value. In letter to the London Times he says: An electrical method of dis sipa ton is not the right remedy for this artif1cially intensified evil, though it is hopeful and proper method of attacking natural mist in places where
