The Making of the Earth, by Prof. J. W. Gregory. London: Williams 
& Norgate, 250 pp., 1s. net.—In this well-bound and very cheap volume 
Professor Gregory summarizes the history of our planet from the time 
it was a nebula. He deals with ancient climates, formation of the earth’s 
crust, earthquakes, upheaval, plan of the earth, geographical elements, 
the biosphere, first life on the earth, etc. 
Rocks and their Origins, by A. J. Cole. Cambridge University 
Press, 175 pp., 1s.—Under the heads of Limestones, Sandstones, Clays, 
etc., Igneous Rocks and Metamorphic Rocks, Prof. Cole gives a charming 
account of the origins of the principal rocks that form the earth’s crust. 
By the aid of several good illustrations his stories are made doubly ‘inter- 
esting. The book is one that can be read and appreciated by a beginner. 
Dana’s Manual of Mineralogy, by W. E. Ford. Thirteenth Edition. 
London: Chapman & Hall, 1912, pp. vi. + 460, 8s. 6d. net.—‘ Dana’s 
Manual’ is almost a household word in English scientific circles, and no 
words of ours are needed to draw attention to its excellent contents. 
Suffice it to say that a new edition—the thirteenth—has been issued, 
which speaks well for the popularity of the volume. There are nearly 
4oo good illustrations in the text. 
Gem-Stones and their Distinctive Characters, by G. F. Herbert Smith. 
London: Methuen & Co., pp. xiv. +312, 6s. net.—Dr. Smith’s connection 
with the Natural History Department of the British Museum peculiarly 
qualifies him for the task of writing a general treatise on Gem-stones, and 
he has been particularly successful. He deals with the subject from the 
practical, geological, and jeweller’s point of view, and in a series of forty 
chapters gives an admirable history of the subject. There are numerous 
plates, some being coloured. The latter, showing the forms of crystals 
in their natural colours, are all that can be desired. 
The Work of Rain and Rivers, by Prof. T. G. Bonney. Cambridge 
University Press, 144 pp., 1s. In this little handbook Professor Bonney 
gives a good summary of the work of rain and rivers in moulding the 
earth’s surface, and deals with (1) Carving and carrying, (2) Making of 
valleys, (3) Transport and deposit of materials, (4) History of a river 
system, and (5) Man’s learning of Nature’s lesson, We notice on his 
first page that Professor Bonney considers that ‘ of late years geologists 
in North America, and the younger school of them in England, have 
often manifested a tendency to exaggerate the effects produced by 
glaciers and ice-sheets,’ and his remarks (pp. 112-113) in reference to the 
dry valleys in Cleveland are very definite. He will have none of the 
younger geologists’ views that they are lake overflow channels, but ‘ they 
are the dry beds of streams which had already flowed far, not of those 
near the beginning of their source.’ We await with interest Professor 
Bonney’s promised ‘ demonstration’ that the form of these valleys is 
irreconcilable with any such glacier-lake origin. At present Professor 
_Bonney’s attitude seems to be like that of ‘ our Bill,’ who was the_only 
one in step in his regiment !
