BOOK NOTICE. 



PHOTOGRAPHY FOR BIRD LOVERS : A PRACTICAL GUIDE. By 

 Bentley Beetham, F.Z.S., with photographic plates. London : 

 Witherby & Co. Price 58. 



The author of this little book is already favourably known in 

 ornithological literature, and therefore former readers will welcome 

 new work from his pen and camera. In the introductory chapter 

 Mr. Bentley Beetham discusses from many points of view the work 

 of the bird-photographer and indicates how a knowledge of field craft 

 must be combined with a practical knowledge of photography before 

 success can be hoped for. In chapter two the question of apparatus 

 is thoroughly gone into, whilst in those following the photographing 

 of different sorts of nests are described, and many practical hints 

 are given as to the manipulation of the camera, etc. Throughout 

 the whole book, which amounts to 122 pages, the author combines 

 to give practical photographic instruction with ornithological lore 

 in a pleasing and instructive fashion. He has much to say about 

 exposure, signals, photography by concealment, etc., and at the 

 same time he initiates us into the ways and habits of the Curlew, 

 Lapwing, and many other birds. The chapter which deals with 

 the photography of birds in flight is particularly interesting, whilst 

 another chapter is devoted to bird photography in colour and in 

 cinematography, two up-to-date aspects of this kind of the Science. 

 As regards the illustrations, Mr. Bentley Beetham is to be con- 

 gratulated on the fine series of photographs which clearly show his 

 ability to act as mentor in " photography for bird lovers."
