First. This interpretation of Genesis is entirely sufficient to remove all apparent collision between geology and revelation. It gives the geologist full scope for his largest speculations concerning the age of the world. It permits him to maintain that its first condition was as unlike to the present as possible, and allows him time enough for all the changes of mineral constitution and organic life which its strata reveal. It supposes that all these are passed over in silence by the sacred writers, because irrelevant to the object of revelation, but full of interest and instruction to the men of science, who should afterwards take pleasure in exploring the works of God. It supposes the six days' work of creation to have been confined entirely to the fitting up the world in its present condition, and furnishing it with its present inhabitants. Thus, while it gives the widest scope to the geologist, it does not encroach upon the literalities of the Bible; and hence it is not strange that it should be almost universally adopted by geologists as well as by many eminent divines. I would not forget to notice in this connection, however, a recent proposed extension of this interpretation by Dr. John Pye Smith, founded on the principle already illustrated, that the sacred writers adapted their language to the state of knowledge among the Jews. By the term _earth_, in Genesis, he supposes, was designed not the whole terraqueous globe, but "the part of our world which God was adapting for the dwelling-place of man and animals connected with him." And the narrative of the six days' work is a description adapted to the ideas and capacities of mankind in the earliest ages, of a series of operations, by which the Being of omnipotent wisdom and goodness adjusted and furnished, not the earth generally, but, as the particular subject under consideration here, a PORTION of its surface for most glorious purposes. This portion of the earth he conceives to have been a large part of Asia, lying between the Caucasian ridge, the Caspian Sea and Tartary on the north, the Persian and Indian Seas on the south, and the high mountain ridges which run at considerable distance on their eastern and western flanks. This region was first, by atmospheric and geological causes of previous operation, under the will of the Almighty, brought into a condition of superficial ruin, or some kind of general disorder, probably by volcanic agency; it was submerged, covered with fogs and clouds, and subsequently elevated, and the atmosphere, by the fourth day, rendered pellucid.--_Script. and Geol._ p. 275, 2d edit.
