MOUTH ORGANS FOR THE FRONT.
New York, January 15.—The demand for music on the part of Tommy Atkins and his brothers in the trenches has resulted in the development of a new industry in this country - that of manufacturing harmonicas or mouth organs. Until war was declared the manufacture of these articles was almost exclusively a German industry. The German product being boycotted, and the supply in England and France soon exhausted, the Allies naturally turned to the United States for their mouth instruments. Thousands of gross of harmonicas have been shipped abroad since the start of the war, and the few musical houses which are equipped to manufacture them are hopelessly behind in their orders.
[One of many appeals for mouth organs to send to the men at the Front is here.]
