ted than is usual in entomological psychology. I find the
ineptness of the undertaker in all the insects reared under the wire
cover, on the bed of sand into which the rim of the dome sinks a little
way. With very rare exceptions, fortuitous accidents, no insect has
thought of circumventing the barrier by way of the base; none has
succeeded in gaining the exterior by means of a slanting tunnel, not
even though it were a miner by profession, as are the Dung-beetles par
excellence. Captives under the wire dome, but desirous of escape,
Sacred Beetles, Geotrupes, Copres, Gymnopleuri, Sisyphi, all see about
them the freedom of space, the joys of the open sunlight; and not one
thinks of going round under the rampart, a front which would present no
difficulty to their pick-axes.

Even in the higher ranks of animality, examples of similar mental
obfuscation are not lacking. Audubon relates how, in his days, the wild
Turkeys were caught in North America.

In a clearing known to be frequented by these birds, a great cage was
constructed with stakes driven into the ground. In the centre of the
enclosure opened a short tunnel, which dipped under the palisade and
returned to the surface outside the cage by a gentle slope, which was
open to the sky. The central opening, large enough to give a bird free
passage, occupied only a portion of the enclosure, leaving around it,
against the circle of stakes, a wide unbroken zone. A few handfuls of
maize were scattered in the interior of the trap, as well as round
about it, and in particular along the sloping path, which passed under
a sort of bridge and led to the centre of the contrivance. 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 c
