Query: Emerald age, my eye !

While this biography of a fine, mysterious player is adequate, Casway's assertion that 19th Century baseball was an "Emerald Age," due to Irish dominance is ludicrous. Almost all the top ball players were of English ancestry at the time, which reflected the U.S. immigrant population. With the exclusion of Negroes, Latins etc. Irish did stand out as a "colorful" minority.
