lties of a body which is not lying on the soil, must possess the
instinct to shake it to the ground. The fortuitous support of a few
bits of stubble, of a few interlaced brambles, a thing so common in the
fields, should not be able to baffle them. The overthrow of the
suspended body, if placed too high, should certainly form part of their
instinctive methods. For the rest, let us watch them at work.

I plant in the sand of the cage a meagre tuft of thyme. The shrub is at
most some four inches in height. In the branches I place a Mouse,
entangling the tail, the paws and the neck among the twigs in order to
increase the difficulty. The population of the cage now consists of
fourteen Necrophori and will remain the same until the close of my
investigations. Of course they do not all take part simultaneously in
the day's work; the majority remain underground, somnolent, or occupied
in setting their cellars in order. Sometimes only one, often two, three
or four, rarely more, busy themselves with the dead creature which I
offer them. To-day two hasten to the Mouse, who is soon perceived
overhead in the tuft of thyme.

They gain the summit of the plant by way of the wire trellis of the
cage. Here are repeated, with increased hesitation, due to the
inconvenient nature of the support, the tactics employed to remove the
body when the soil is unfavourable. The insect props itself against a
branch, thrusting alternately with back and claws, jerking and shaking
vigorously until the point where at it is working is freed from its
fetters. In one brief shift, by dint of heaving their backs, the two
collaborators extricate the body from the entanglement of twigs. Yet
another shake; and the Mouse is down. The burial follows.

There is nothing new in this experiment; the find has been dealt with
just as though it lay upon soil unsuitable for burial. The fall is the
result of an attempt to transport the load.

The time has come to set up the Frog's gibbet celebrated by Gledditsch.
The batrachian is not indispensable; a Mole will serve as well or even
better. With a ligament of raphia I fix him, by his hind-legs, to a
twig which I plant vertically in the ground, inserting it to no great
depth. The creature hangs plumb against the gibbet, its head and
shoulders making ample contact with the soil.

The gravediggers set to work beneath the part which lies upon the
ground, at the very foot of the stake; they dig a funnel-shaped hole,
into w
