FIRST TARGET TOURNEY.
About 1880 the first of saucer-shaped targets was thrown at a tournament held in Springfield, Illlinois. The disc was known as the Ligowsky clay pigeon, and it very quickly succeeded as a test of marksman ship the glass ball then in vogue as a flying target.
The first
Interstate event was held in New Orleans a short time after the Springfield event, and attracted a large field. Harvey McMurchy, now one of the firm of the Hunter Arms Company, was the winner. Thirty years later, in 1910, in the Grand American Handicap at Chicago, he scored ninety-nine out of one hundred, proving that art is of more avail than youth, and that a man of sixty or seventy has the same chance as a man of twenty or thirty.
