ACKNOWLEDGEMENTS
I wish to acknowledge the great kindness of Dr. L. Hussakof, at that time Curator of Reptiles in the American Museum of Natural History, New York for reading and correcting the first ten chapters of this book, and for his many kind words and deeds. When I offered to pay for the trouble he wrote me “all the pleasure of being helpful in an unselfish way would be gone if I received pay.” Dr. W. D. Matthews, Curator of Vertebrates in the same Museum also encouraged me greatly by hoping I would publish my ideal picture of “Ancient Giants” after reading the chapter I sent him under that title. All the rest I am responsible for, as I have had no assistance, and if I have published any thing that does not please my reader I hope they will overlook it.
How can I thank the Director of the Geological Survey of Canada, and Deputy Minister, Mr. R. G. McConnell, who has allowed me to use the photographs taken by my sons George and Charlie, to illustrate my pages. The text would have been dull indeed without them. Neither can I express my thanks for his unfailing kindness to me while I was under his authority as a member of the Survey. All the photographs (except the Front Piece Figures 1, 2, and 3, which were sent to me by my old friend, Dr. Osborn, President of the American Museum of Natural History, New York. The picture of a Portheus, from the London Illustrated News, the Figure of a Tylosaur by my son George F. Sternberg. The restoration of Diplodocus carnegii by Mr. C. W. Gilmore of the U. S. National Museum, and the figures 43, 44, and 45 taken last year by my son Levi) belong to the Survey. Mr. Clark in charge of the Division of Photography developed the photographs, and the Terre Haute Engraving Co. made the halftones. Neither can I forget the unvarying kindness of the former Deputy Minister, Dr. R. W. Brock who first employed me. For the great assistance he rendered me in field and shop. For his earnest assistance to help me build up a great collection of the Extinct Animals of Canada, at the Victoria Memorial Museum at Ottawa, Ontario. I hope these gentlemen and all others who have helped me to that end, will feel themselves included in this letter of thanks.
Faithfully yours,
Charles H. Sternberg.
