In the same manner Artesian wells have been sunk in other places, as at Hampstead Water Works, 450 feet deep; Combe & Delafield’s, 500 feet deep; and the Trafalgar-square Water Works, 510 feet deep.[10] Now, the reader has only to take this last diagram, and in imagination to apply it to the one on page 21, in order to see that so far as actual boring and investigation go, the geological theory of the earth’s crust is correct; only again let it be observed that this order is never inverted, although it frequently happens that some one or more of the strata may be absent. Hitherto we have spoken of the earth’s crust without reference to that wondrous succession and development of living beings which once had their joy of life, and whose fossil remains, found in the different strata, waken such kindling emotions of the power of Deity, and enlarge indefinitely our conceptions of the boundless resources of His Mind. This will open before us a new chapter in the history of our planet, already the theatre of such vast revolutions, and which, under the influence of Divine truth, is yet to undergo one greater and nobler than any of these. We have as yet only glanced at the surface page of the wondrous book, now happily opened for us by geologists, to whose names we have already made reference; and as the mind rests with intense pleasure on the discoveries of Champollion, Belzoni, Lane, Layard, Botta, and others who have deciphered the hieroglyphics, in which were written the wars and the chronicles of ancient nations, whose names and deeds are becoming, by books and lectures, and above all by our noble national Museum, familiar even to our children, and a source of help and solace to the hard-toiling artisan; so with profounder interest, as carried back into remoter ages of antiquity, so remote that they seem to lie beyond the power of a human arithmetic to calculate, do we humbly endeavour to decipher the hieroglyphics,[11] not of Egypt or of Nineveh, but of the vast creation of God, written in characters that require, not only learning and science to understand, but modesty, patience, and triumphant perseverance. He who with these pre-requisites combines reverence for God and His revelation, will always find in Geology material both for manly exercise of thought, and also for reverent adoration of Him who is Himself unsearchable, and whose ways are past finding out. “We not to explore the secrets, ask Of His eternal empire, but the more To magnify His works, the more we know.”—MILTON.
