Gentlemen: 
Yesterday afternoon. Sept. 15th, I shot several ducks and when 
I got back to town I noticed the enclosed tag Ho. 3814 attached to the 
leg of one of them. The duck was flying with a flock of mallards and 
was the only canvasback in the flock. 
The duck was killed in the Mahon-Hoyt reservoir about six miles 
southwest of Glasgow. This flock of about thirty-five ducks has been 
inhabiting the reservoir for about two weeks. The water covers about 
150 acres and is a breeding place. 
I would be very glad to hear the circumstances under which this 
duck was liberated, as I am very interested in all kinds of game. 
Very truly yours. 
Geo. W. Sweitzer.
