Who would dare disturb the beatitude of such a banquet? Alas! the
desire for knowledge makes one capable of anything, and I have not
shrunk from even this. I now give the result of thus violating the
sanctity of home-life. The ball filled almost the whole space, the
magnificent store of victuals rising from floor to ceiling, a narrow
passage separated it from the walls. In this sat the banqueters, two at
most, often but one, their faces to the table, their backs to the wall.
When once they have taken their places nobody stirs, all their vital
powers are absorbed by the digestive faculties. No little movement
which might cause the loss of a mouthful, no daintiness which might
waste the food—everything must be done decently and in order. To see
them thus absorbed round a lump of dung, one would say that they were
aware of their rôle as earth-cleansers, and consciously devoted
themselves to that marvellous chemistry which out of impurity brings
the flower that gladdens the eye, and the wing-cases of the Scarabæus
which adorn the turf in springtime. To fit it for this all-important
work, which turns into living matter the residue that horse and sheep
cannot utilise, in spite of the perfection of their digestive organs,
the dung beetle needs special tools. Accordingly anatomy shows the
immense length of its intestine, which, folded repeatedly on itself,
slowly deals with the material in its manifold circuits, and exhausts
the very last atom capable of being used. Where the stomach of the
herbivorous animal can extract nothing, this powerful alembic draws
riches which under its influence become the ebony mail of the Scarabæus
sacer, and a cuirass of gold and rubies for other species. Sanitary
principles require that this marvellous change be made as rapidly as
possible; therefore the Scarabæus is endowed with a matchless power of
digestion. Once shut up with food, it never ceases to eat and digest
until the whole store is devoured. Proof of this is easily come by.
Open the cell where it has retired from the world at any hour and you
find the insect eating, and behind it, still attached to the creature,
is a continuous cord, rolled carelessly like a bundle of cables.
Without going into particulars, we can guess what this cord represents.
Mouthful by mouthful the great ball passes into the digestive organs,
yielding up its nutritive principle, and reappearing spun into a rope.
Now this unbroken cord, often without a joint and always hanging from
the orifice, proves, with absolute certainty, how continuous is the
action of digestion. By the time that the food is nearly eaten, the
rope is astonishingly long. Where else could one find another stomach,
that, to avoid any loss in the debit and credit ledger of life, can
feast for a week or a fortnight on such miserable cheer? When the whole
mass has been digested, the hermit returns to daylight, seeks, finds,
and shapes a new ball, and begins all over again. This royal life lasts
