In attempting to compile this brief dissertation on the history and development of the Thoroughbred horse in America, I found myself confronted with an immense task. The every detail in the development and improvement of our modern racer would be impossible to incorporate in an article as brief as this, and would require a knowledge and skill much beyond my humble capability. Therefore, I have attempted to enumerate but a few of the more pertinent steps concerning the development of the American Thoroughbred horse. I have cited several of the most outstanding men of the turf and sporting world of both the past and present generation. I have endeavored to present as accurately as possible, and to the best of my knowledge the facts behind this truly great American enterprise.
