The first complete manual of Aerial Photography has just been

published by Messrs. Winchester and Wills (Chapman and Hall, 25s.). It is a beautifully illustrated book and of interest to the amateur as well as to the professional. There are short articles by Sir Alan Cobham and by Sir Peter Clutterbuck, the latter on the aerial survey of forests. Of the archaeological importance of aerial photography we have already written. Mr. 0. G. S. Crawford is fully quoted here on the subject and there is no doubt we may expect great developments in this direction. However, the charting of difficult countries and the survey of inaccessible forests remain the fields in which this new art or industry will be pre-eminent.
