From the time of Herodotus until to-day, lion stories innumerable have been told and written. I have put some on record myself. But no lion story I have ever heard or read equals in its long-sustained and dramatic interest the story of the Tsavo man-eaters as told by Col. Patterson. A lion story is usually a tale of adventures, often very terrible and pathetic, which occupied but a few hours of one night; but the tale of the Tsavo man-eaters is an epic of terrible tragedies spread out over several months, and only at last brought to an end by the resource and determination of one man. It was some years after I read the first account published of the Tsavo man-eaters that I made the acquaintance of President Roosevelt. I told him all I remembered about it, and he was so deeply interested in the story-as he is in all true stories of the nature and characteristics of wild animals-that he begged me to send him the short printed account as published in The Field.
