When the earth was in a state of fiery fluidity, all of the water it now contains was suspended at a great distance above it. Beside the oceans which now cover three-fourths of the surface of the globe, rocks and coals contain from ten per cent to one half water, all of which was primarily held in suspension. The bosom of the earth is continually absorbing water as is demonstrated by deep mines and other excavations. Dana estimates that even if the crust of the earth is but five miles thick that the oceans would be 400 feet deeper if all of the earth’s imbibed waters could be returned to them. But the earth’s crust is more likely to be 100 miles thick, and it has been imbibing these waters for millions of years if not millions of ages. This would increase the oceans to about 8000 feet deeper than now. Yet oceans are much deeper today than they were in geologic times. This great mass of vapor would rotate by centrifugal force at the equator, but there being no such force at the poles it was there kept from falling by heat alone. If the earth had not rotated the vapors would have occupied great heights; but centrifugal force being aided by actual rotation they were driven much farther. These forces necessarily drove the vapors over the equator. If, however, any vapors were left at the poles they must have fallen when the earth cooled down. At that age rolled the first born ocean around the globe. Clouds formed, rain descended, and winds swept the earth. There was summer and winter, and day and night. The centripetal force of the rings was gradually retarded by the influence of the moon, and the gravital force was increased until the rings spread over the earth or approached it. When the innermost ring gradually descended toward the earth and came in contact with the air it was checked, and necessarily spread out toward the poles. Gravital force is strongest in the polar regions. If the rings of Saturn and Jupiter could increase their motion they would rise to greater heights. If they could become slower they would sink toward the poles. EVIDENCE FROM OTHER PLANETS. We have never seen the actual face of Saturn, and the sun is never visible to its inhabitants. It is a planet upon which there is probably perpetual day. The belts are composed of the same kind of material as the super-crust of the earth--silicious, calcareous and carbonaceous matter. They will in time become a part of the planet’s sedimentary formation. When the inveterate fires of the sun shall have died out, forms of carbon and associated forms of aqueous and mineral matter will form an annular system around it. A burning world must be a smoking world, and from its furnaces must arise vast volumes of unconsumed carbon to mingle with suspended vapors.
