Divisional planes are developed in them, some being due to crush, some to shrinkage, some to the variety in the succession of deposits, and when the strained and bending rock must break it is apt to give along these lines of weakness, so that we find faults commonly coinciding with master joints, thrusts with bedding planes, and so on.

The last seven chapters are more specially devoted to the second subject in the title of the book, namely, field geology. This could not be altogether dissociated from the observations recorded in the earlier part of the work. The information there given is the outcome of original observations in the field, but our author now deals more with the methods employed, and explains what are the most useful appliances for the work and what are the indications which the surveyor must be on the alert to detect. Perhaps, having regard to the numerous monographs which have recently been published on the subject of scenery, he has given greater prominence to the causes than to the effects, to the earth structures to which most scenic features must ultimately be referred rather than to the total result of movement and denudation by which anomalous river flows and abnormal features must be explained.

A study of recent organisms enables us sometimes to establish the relation between the soft and perishable parts and the hard parts which alone are commonly preserved in the rocks, and thus by a comparison of the fossil forms with their nearest recent representatives to learn something of the order of succession of life upon the earth and the conditions under which fossil plants and animals existed. Such analogies must not, however, be pressed too hard. Even such a recent case as the occurrence together of the remains of lion, hyæna, and hippopotamus with the hairy elephant and woolly rhinoceros in our gravel
