Author Description

Excerpt from Economic Geology: Or Geology in Its Relations to the Arts and Manufactures In the next place, take the case of the Civil engineer who has to plan and lay down roads and railways, to execute cuttings and tunnels, to excavate docks and harbours, to erect piers and breakwaters, to deepen and widen tidal rivers, and bring in water-supplies to towns. Not a step can be taken in any of these important Operations without coming in contact with geological phenomena - not a plan can he lay down which does not depend more or less on a knowledge of rocks and rock-formations. It is true he may obtain information from geological maps and from professional geologists; but, even with this aid, his work will be executed with feebleness and uncertainty compared with that of one who can discriminate the geological structure of a country for himself. And it has simply been, and still is, for want Of this geological knowledge that so many of our engineering works have been executed at so much cost and with so little pecuniary satisfaction to their proprietors.
