For 1865 there were only 30 members with not one in New England and western outliers merely in Washington, Altoona in southwestern Pennsylvania, and Utica in central New York state. But the December 1865 meeting attracted triple the membership with scattered clubs from Chattanooga, Tennessee to Fort Leavenworth, Kansas. During the next three seasons, the National Association "filled" with clubs further west from St Louis and Iowa to the northeast in Boston and Maine. By 1867 there were too many delegates to handle in convention, so membership via state associations was introduced for 1868 and, perhaps for that reason, there is no reliable enumeration of the members from 1868 to 1870.
