"The science of geology largely engages the attention of the public; but persons are frequently deterred from the study of it by the dry and tedious style of writers dedicating their talent to its exposition. Professor Ansted has supplied a book which meets the public want.... The chapters relating to agricultural geology have an especial interest for farmers; but the whole are deeply interesting and worthy of recommendation."-News of the World. "Professor Ansted takes in hand a subject of some difficulty, but of universal importance. In this he describes the different kinds of mineral veins, their contents, and the methods adopted to extract those contents, and thus fitly concludes his labours in elucidation of the practical application of geological knowledge to economic purposes, especially in connection with the arts."-Daily News.
