Sportsmen and ornithologists will be interested in 

 the list of Labrador birds by Mr. L. W. Turner, 

 which has been kindly revised and brought down to 

 date by Dr. J. A. Allen. Dr. S. H. Scudder has con- 

 tributed the list of butterflies, and Prof. John 

 Macoun, of Ottawa, Canada, has prepared the list of 

 Labrador plants. 



Much pains has been taken to render the bibliog- 

 raphy complete, and the author is indebted to Dr. 

 Franz Boas and others for several titles and impor- 

 tant suggestions; and it is hoped that this feature of 

 the book will recommend it to collectors of Ameri- 

 cana. 



It is hoped that the volume will serve as a guide 

 to the Labrador coast for the use of travellers, 

 yachtsmen, sportsmen, artists, and naturalists, as 

 well as those interested in geographical and histori- 

 cal studies.
