These instances are only two out of thousands of a similar nature in this country and all over the world. The tendency of this drift is mostly as the streams of water run toward the Equator or center of greatest motion. The vast deserts and other accumulations of sand on the Earth are only the deposits of ancient rivers into then existing seas, which by later surface upheavals, by interior hydraulic forces, have been transferred to other beds, and the deserts like Sahara, Atacama, Mojave, and the Steppes of Asiatic Tartary, remain as evidences. By these enormous changes of soil it seems rational to believe the uniform and unvarying revolution of the Earth could hardly be possible, and that more or less change during great length of years must be made in form as well as time of revolving. Have not both occurred? Riding down the Quinnipiac Valley to New Haven, Conn., a man is likely to inquire in his mind where those sand plains came from. Some think the Connecticut once flowed there, some the Niagara or St. Lawrence; if so, where did they bring the sand from? Think of the change bound to come in the future, when the Falls of Niagara cut their way back to Lake Erie, thus letting out its waters, enough to construct it into a large river. Some channel has evidently been lowered to settle the surface of Lake Michigan, as can be plainly seen in leaving Chicago by boat, that the waters on the western banks were once twenty or more feet above present level. Either the lake has settled or the land has risen. As deserts are nearly all below the ocean surface, is it not presumable that this enormous accumulation of sand has had the effect of such depression, while the transference from other localities has thinned Earth’s crust enough to make easy the internal water pressure to lift up the hills and mountains, through which the great water courses of the Earth are supplied? Think of the transportation of soil to the deltas of the Mississippi, Amazon, Ganges and other rivers amounting to millions and millions of tons every year, and imagine when the time will come when the Earth approaches the form of a wheel, or ring, nearer than a globe, and become a small imitation of Saturn. Assuming that this is, and has been one cause of the great upheavals, is it not suggestive that the original of the Earth’s surface in its formation millions of years past, was nearly or quite free from hills, and mountains, and the inside as well as exterior has been undergoing radical changes? Great masses of earth on the outside accumulated by floods and washed from higher points have dammed up and smothered the flow from inside, while the sections of the Earth that have contributed to this mass have been thrown up into exterior mountains, and the depressions made inheavals to a corresponding extent.
