New interests evolved as the major Canadian radar lines were constructed. Military personnel and prospectors needed data on northern physiography and living conditions. One significant achievement was the development, by a British supplier, of the Decca navigation equipment. Some sort of bibliography of projects or research papers is needed, however, to help the reader evaluate the relative extent of the P.C.S.P.'s involvement in Arctic science. A large portion of this book is devoted to photographs.
Picture quality is often poor on the black and whites.
Many seem to have been developed in the field, under difficult conditions. Retouching and cropping to remove hair and dirt is needed. Still some, such as the ice island picture, are unusual and very interesting. This book is short and easy to read, but the subject is so narrow that it will have limited appeal to those who are not already familiar with the P.C.S.P.
