This is a rubber duck of full size, and accurately formed. When not in use it can be collapsed by allowing the air which distends it to escape through,1 a valve provided for that purpose .and through which it is also inflated when it is wanted for use. A ballast weight is fixed to the center of the belly. The resemblance to a real duck is very striking. Sportsmen will appreciate this invention, and the convenience afforded by the portability of these decoys over the old cumbersome wooden ducks. A dozen may be packed so as not occupy more space than a single wooden one. Patented August 3, 1869, by Jacob Foster, who may be addressed for further information, 328 Colowhill street, Philadelphia, Pa.
