Life is too short to compile a book that would cover the subject fully, hence this work is not a detailed history of the great petroleum development. Nor is it a mere collection of dry facts and figures, set forth to show that the oil business is a pretty big enterprise. But it is a sincere endeavor to print something regarding petroleum, based largely upon personal observation, which may be worth saving from oblivion. The purpose is to give the busy outside world, by anecdote and incident and brief narration, a glimpse of the grandest industry of the ages and of the men chiefly responsible for its origin and growth. Many of the portraits and illustrations, nearly all of them now presented for the first time, will be valuable mementoes of individuals and localities that have passed from mortal sight forever. If the reader shall find that within is more of relish than of cost the writer of these Sketches will be amply satisfied.<br><br>The first edition of five-thousand copies having been exhausted, the second is now issued. The oil-development is progressive, hence numerous illustrations and much new matter are added. Hearty thanks are returned hosts of friends and the public generally for kindly appreciation of the work. Perhaps something not thanks may be due the lonely few who "care for none of these things." This will likely end the pleasant task of reviewing petroleum's wide field and "living the old days over again," so it is fitting to pray, with Tiny Tim, "God bless us every one."
