Lieut. Arthur W. Du Bray resigned his commission in the United States Army, to take effect Jan. 1, and in future Gaucho will be connected with the Parker Bros., traveling in the interest of the Parker gun. He and Mr. Tucker will divide the territory of the United States, so that the visits of the representative of the Parker Bros, will be more frequent than heretofore in the various localities.
