A frame between two and three feet square is made, and of a greater or less height, according to the depth of water. Boards or slats are nailed on three sides of this frame, not so closely, however, as to prevent the water circulating freely through it. A door is fitted into the fourth side, in such manner that it will slide easily up and down in the grooves cut in the two posts. A movable bottom is then so fitted that it can be raised to the top of the frame without difficulty. In the centre of the movable bottom an auger hole is bored, and into this one end of a handle or round stick is fastened on the under side so loosely that it will turn. The handle ascends from the centre of the movable bottom to the top of the frame, or as much higher as is desirable. Up and down this handle, in a great many places, are gimlet holes, through which small sticks are inserted, extending to opposite sides of the frame. So many of these small sticks are running out from the handle in all directions, that a fish of any considerable dimensions cannot pass through without hitting one of them. The frame is then placed in the water and made stationary.
