BIRD MIGRATION.* 
The nature of this valuable report, issued by the British 
Ornithologists’ Club, was described in detail in our issue for 
May last year. The present report is on the same lines, and 
is similarly lavishly illustrated by maps showing the distribution 
of the various species referred to. Messrs. C. B. Rickett and 
C. B. Ticehurst have been added to the Migration Committee. 
Mr. J. L. Bonhote is largely responsible for classifying the 
records, and Dr. N. F. Ticehurst has prepared the maps. 
These most useful reports of the ‘ B.O.C.’ will unquestionably 
go a long way towards solving the complex problems of bird 
migration.

A Text-book of Plant Diseases, by George Massee (Principal 
Assistant (Cryptogamic) Royal Herbarium, Kew). Duckworth & Co., 8vo. 
pp. xx., 472. Third edition, 6/- net. 
This is the third edition of Mr. Massee’s book, which speaks well for its 
popularity. We have had the book in constant use for several years, and 
proved its value to gardeners, nurserymen, and others. While the most 
important diseases are described and illustrated and the means of prevention 
and cure given, we find that the criticism of the average English gardener 
is that while several diseases not known in this country are described, a 
number of parasites frequent on plants in general cultivation, and some of 
these very destructive, are omitted. In a future edition it would be well to 
extend the types in this direction. This edition agrees closely with the 
second, except that eight pages have been inserted in front of the introduction 
dealing with the black scab of potatoes, American gooseberry mildew, and 
a cluster-cup disease of conifers ; and the price has been slightly increased. 
The Gamekeeper’s Manual, by Alexander Porter. David Douglas, 
Edinburgh. 140 pp., 3/- net. The fact that this is the third edition of this 
popular manual shows that the work of the Chief Constable of the counties 
of Roxburgh, Berwick, and Selkirk is appreciated, and serves a useful 
purpose. It deals with poaching, day trespass, preservation of game, poison, 
taking or destroying eggs, owners’ and occupiers’ rights, The Wild Birds 
Protection Acts, the powers and duties of a gamekeeper, etc., etc., and the 
author is naturally a well-qualified person to deal with the subject. It is 
interesting to note with regard to the Wild Birds Protection Act that ‘there 
is no special power given to anyone to enforce the Act. Any Person, on 
seeing an offence committed, may demand the offender's name and address, 
and if he refuses or gives a false name or address he renders himself liable 
for an additional penalty for so doing.’ There is much in the book that 
might well be perused by others besides gamekeepers !
