Historians have sometimes confused Longdale with Cainville. The latter was north of Longdale, and already had a post office, where the residents of Longdale could receive their mail. The Cainville post office was discontinued and moved to Longdale on November 28, 1903, with Robert L. Eaton as the new postmaster. On October 23, 1903, G. W. published the first edition of his newspaper, the "Longdale Register". The Longs already had sold part of their property to the Kansas City, Mexico and Orient Railway, which finally reached Longdale on June 10, 1905.
