The uniforms of the United States army was reduced to the plainest possible standard by Jeff. Davis, when Secretary of War, and there is but a trifling difference between the costumes of dragoons, artillerymen, infantry, or engineers, all of whom wear clothing of the same color and cut, different trimmings alone distinguishing each arm of the service. This is economical, but it fails to inspire the men with a soldier-like pride by fostering a commendable rivalry between different corps.
