Ant Trap.

Patent for a new and improved ant trap. This design calls for a tank of water to be buried in the ground and a collar of cheap material to be attached to the tank and placed over the mouth of an anthill. The concave nature of the collar prevents ants from climbing out of it, so they are forced into the water tank, where they drown; the design is cheaper and less toxic than previous designs.
