2 DUCK DOLLARS 
Food-Mixing Machine 
This is really a machine used by bakers for mixing dough, but it is just what is 
wanted for mixing the rations for ducks. This size cost $320, but it saves the labor 
of two men. There is a smaller size sold at half that price. The mixer shown in 
above picture is run by power, a gasoline engine. The steel hopper is stationary, 
and the mixing is done by two horizontal revolving metal paddles, moving in opposite 
directions.
