PREFACE TO THE SECOND EDITION 



It is now more than five years since the first edition of 

 this work appeared. 



It has been found necessary to add to the meagre descrip- 

 tions of some of the birds and to add many species omitted 

 in the previous edition. We have done this owing to the 

 fact that the work has been kindly approved by the Trans- 

 vaal Education Department and added to their list of 

 authorised books. 



We have to thank Mr. M. J. Nicoll for the loan of several 

 blocks from his " Three Voyages of a Naturalist," illustrating 

 the chapter on Seabirds, and to Mr. E. Chambers for the 

 photograph of the Breeding Colony of the Cliff Swallow.
