Notes and Comments. 227 



Fordham (84 pages, 7/6 net). Sir George, was one of the 

 first in recent years to draw particular attention to the valuable 

 information to be derived from a study of old topographical 

 maps, and in the present little volume he brings together, in 

 permanent form, a series of five lectures delivered in Cam- 

 bridge, to the teachers of Cambridgeshire. He refers to the 

 history of map -production from the earliest times, and by the 

 aid of illustrations from typical maps of various periods, 

 gives a very fascinating narrative. 



GEOLOGICAL MAPS. 



The same house has issued ' The Study of Geological 

 Maps,' by Dr. Gertrude L. Elles (74 pages, 12/- net). In 

 her case, likewise, the book is based upon notes for a course 

 of lectures, in this instance given to successive generations 

 of Girton and Newnham students, and there is no doubt that 

 the author has been well advised in bringing her notes together 

 in this useful way. Dr. Elles has a charming style, and, 

 in addition, a thorough knowledge of the various complicated 

 measurements necessar}^ in mapping, so that her book applies 

 equally to beginners and to advanced students. The volume 

 is illustrated by an enormous number of diagrams, sections 

 and maps, each of which has been carefully selected to illus- 

 trate some particular point. 



MAP READING.* 



The author is a member of the Army Educational Corps, 

 and this book is entirely devoted to the question of read- 

 ing military maps. The scope of the work can be judged 

 from the following headings of chapters : The Compass, The 

 Scale, The Contours, Gradients, Visibility, Conventional Signs, 

 Map References, etc. There are appendices, and an enormous 

 number of sketches and diagrams illustrating various aspects 

 of Map reading, at the end of the volume. 



SKETCH-MAP GEOGRAPHY. f 



Under the above title, E. G. R. Taylor has written ' a 

 text -book of World and Regional Geography for the middle 

 and upper schools,' on new lines. Instead of the text being 

 illustrated by maps, the book consists of 160 maps, supple- 

 mented by a series of brief explanatory notes. The sketch- 

 maps 'show different categories of facts in combination when 

 they are seen to be, not merely facts, but factors, determining 

 some particular result.'

 be quite certain.
