EARTH WAVES.

SIE G. DARWIN SAYS THE LAND MOVES IN TIDES. Sir Geo. Darwin, speaking ou Monday, February 22nd, at the Authors' Club on the subject of "The Influence of Tides on Men," explained that the object of the recent experiments in Berlin was to determine how much the earth was moving. He believed the earth moved up and down twice a day, perhaps three or four Inches, like the waters of the ocean.

He had urged Dr. Hecker, of Berlin, to analyse his Investigations and discuss them with the Incidence of high and low barometer. Personally he had calculated that when the barometer showed 30iu., Instead of, say, 28.75, there was a difference In weight of half a ton on every square yard of the earth's surface, and when the barometer was high we were four inches nearer the middle of the earth.

The tides acting on the earth In one dltection served as a brake, making It spin more slowly, and still more slowly.

"A -reaction follows, the result of which is to drive the moon further and further away from the earth. Such a conclusion Is obvious, but a remarkable fact is that whenever the moon approaches more closely to the earth, it always faces the same side of the earth.

"That points clearly to the fact that In very early times the moon and earth were one body, which spun so fast that it broke in two. This view is generally accepted by men of science, some of whom have even speculated on which part of the earth the moon broke away from. It has been suggested that the Pacific Ocean was the hole left by the moon.

"If, Instead of looking backward we look forward, we shall find the ear:h going slower, with the result that eventually the day will last fifty-five times as long as It does at present."

M. Camllle Flammarion's similar theory regarding the diurnal rise and fall of the earth's surface has been the subject of Investigation for years past In the observatory at Klmberley. The most delicate instruments show that the earth crust rises and falls gradually over eight inches once dally, dwarfing the movements of the greatest earthquakes.

The movement Is not tidal. It Is probably connected with the sun's Influence, but up to now the phenomenon is Inexplicable. South Africa also tilts to the east in summer and to the west in winter. This is probably traceable to the seasonable rainfall.
