Insect Trap. (open access)

Insect Trap.

Patent for a new and improved ant trap. This design calls for a box to be placed over the mouth of an anthill, whereupon one expects the ants to enter a hole, climb an incline, and slip down a pair of glass pieces that lower the ants into an inescapable chamber. This design is cheaper and easier to make than previous ant traps.
