Steve posted some excellant photos of the old river boats going down the Lachine rapids and one of his photos showed the same photo that I posted but the name of the boat shown is "Rapid King" therefore my photo is not the "Rapid Prince". Here is a photo of the "Rapid Prince". Sorry for the confusion and thanks Steve for the photo wich helped me correct my mistake. The photo I originally posted was on the cover of the book I consulted for my article and did not mention the name of the boat wereas Steve's photo did wich helped me discover the error. Both boats were very similar wich led to the confusion.
