In short, the Turkey-trap presented an ever-open door.

The bird found it in order to enter, but did not think of looking for it in order to return by it.
According to the famous American ornithologist, the Turkeys, lured by the grains of maize, descended the insidious slope, entered the short underground passage and beheld, at the end of it, plunder and the light.

A few steps farther and the gluttons emerged, one by one, from beneath the bridge.

They distributed themselves about the enclosure.
The maize was abundant; and the Turkeys' crops grew swollen.
When all was gathered, the band wished to retreat, but not one of the prisoners paid any attention to the central hole by which he had arrived.

Gobbling uneasily, they passed again and again across the bridge whose arch was yawning beside them; they circled round against the palisade, treading a hundred times in their own footprints; they thrust their necks, with their crimson wattles, through the bars; and there, with beaks in the open air, they remained until they were exhausted.
Remember, inept fowl, the occurrences of a little while ago; think of the tunnel which led you hither! If there be in that poor brain of yours an atom of capacity, put two ideas together and remind yourself that the passage by which you entered is there and open for your escape! You will do nothing of the kind.
