It is obviously the principle or method of this scheme of reconciliation between Genesis and geology to look for points in the Mosaic narrative which correspond with the facts revealed by geology. The words in the Scriptural account are few; are they so express, vivid, and characteristic that they epitomise, as in a Divine telegram, the geological history of millions of years? A consummate artist looks upon a face and throws a few strokes, quick as lightning, upon his canvas. The countenance seems to live. Revealings of character, which we might have required years to trace, flash on us from the eye, and chronicles of passion are written in a speck of crimson on the lip. The portrait is only a sketch; weeks or months might be spent in elaborating its colour, and perfecting its gradation of light and shade; but not less on this account, does it accurately correspond with the original, and show the man to those who knew him. The advocates of the Age theory of Mosaic geology maintain that, few as are the touches in the pictured history of the world in the first chapter of Genesis, the geologist can recognise them as unmistakeably true to the facts of the past. The correspondence alleged to exist has been illustrated in yet another fashion. Look upon a mountainous horizon, in the far distance, on a clear day, and you perceive a delicate film of blue or pearly grey, relieved against the sky. The outline of that film, faint though it be, is, for every kind of mountain range, more or less characteristic. The horizon line of the primaries will be serrated, peaked, and jagged. The horizon line of the metamorphic hills, though fantastic, will have more of curve and undulation. The horizon of the tertiaries will be in long sweeps, and tenderly modulated, far-stretching lines. Those minute jags and points of the primaries are dizzy precipices and towering peaks. The glacier is creeping on under that filmy blue; the avalanche is thundering in that intense silence. Rivers that will channel continents and separate nation from nation, bound along in foaming cataracts, where you perceive only that the tender amethyst of the sky has taken a deeper tinge. That undulating line of the crystalline hills tells of broad, dreary moors, dark, sullen streams, sparse fields of stunted corn. That sweeping, melting, waving line of the tertiaries tells of stately forest and gardened plain, of lordly mansions and bustling villages. The Mosaic record, as interpreted by the advocates of the Age theory, gives the _horizon lines_ of successive geological eras. Its descriptions, they maintain, are correct, viewed as horizon lines. They convey the largest amount of knowledge concerning the several periods which could possibly be conveyed under the given conditions. Such is the method or logic of the Age theory of Mosaic geology; and it is manifest that, whatever may be its scientific value, it is no more to be refuted by the mention of geological facts which the Mosaic
