Pros and Cons. By John Bertram Askett. Edited by 'W.

T. S. Sonnenschein, B.A. (G. Routledge and Sons. is. net.)- -This " Guide to the Leading Controversies of the Day " was first pub- lished fifteen years ago. It has been rearranged and, to a certain degree, rewritten by the present editor. Some "controversies" have disappeared ; in some the ground has been more or lees changed. On the other hand new ones have appeared. No one, for instance, was worried in 1896 by the "Daylight Saving Bill." Here, by the way, is a "con" argument in this particular question. Cricket matches begin on the second and third days at 11 a.m. This law would be altered to what is now 10 a.m., but in the later part of the season the dew on the ground would make it imprao- ticable. This should be a very useful book.— We may notice at the same time a book which deals with what is at once the oldest and the newest of subjects, flying. This is The Art of Aviation, by R. W. A. Brewer, " a Handbook upon Aeroplanes and their En- gines." (C. Crosby Lockwood and Son. 10s. 6d. net.)
