Our bookshelves contain the lives or narratives of adventure of many hunters of living game, but the life of a fossil hunter has never been written before. Both are in the closest touch with nature and, therefore, full of interest. The one is as full of adventure, excitement and depression, hope and failure, as the other, yet there is ever the great difference that the hunter of live game, thorough sportsman though he may be, is always bringing live animals nearer to death and extinction, whereas the fossil hunter is always seeking to bring extinct animals back to life. This revivification of the past, of the forms which once graced the forests and plains, and rivers and seas, is attended with as great fascination as the quest of live game, and to my mind is a still more honorable and noble pursuit.
