The Canadian officials in the Ottawa Finance Department admitted that the picture on the face of the new Canadian four-dollar bill is that of the American “Soo” lock. The Finance Department sent a request to Montreal for a picture of the Canadian lock at the Sault. In reply they received a picture of the American lock and used it. The officials say they were misled by noticing the Canadian Pacific steamer Athabasca in the lock and assumed in consequence that the picture was all right. The department of railways and canals was not consulted in the matter.
