Provender being gathered, the next thing is to retire from the mêlée,
and carry it to a fitting place. Now we see some of the most
characteristic habits of the Scarabæus. He sets out at once, embracing
the ball with the long hind legs, whose talons, planted in the mass,
serve as pivots—leans on the intermediary legs as pivots, and using as
levers the flat of the toothed forefeet, which press the ground
alternately, journeys backward with his load, the body bent, the head
low, and the hinder part upraised. The hind feet, which are the chief
organs in the mechanism, move continually, going and coming and
changing the place where the talons are stuck in, to alter the axis of
rotation, to keep the load balanced and advance by an alternate push
right and left. Thus the ball comes in contact with the ground in every
part of it, which gives it a perfect shape and lends consistency to the
outer layer by a uniform pressure. Courage! it moves, it rolls, and the
journey’s end will be reached, though not without trouble. Here is a
first difficulty. The beetle has to cross a slope, and the heavy ball
would naturally follow the incline, but for reasons best known to
itself, the insect prefers to cross this natural slope—an audacious
plan, which one false step or a grain of sand to upset the balance will
defeat. The false step is made, the ball rolls to the bottom of the
valley, and the insect, upset by the impetus of its load, staggers,
gets again on its legs, and hastens to harness itself afresh. The
mechanism works capitally. But look out, scatterbrain! follow the
hollow of the valley, it will spare labour and misadventure. The road
is good and quite level, and your ball will roll along with no
exertion. Not a bit of it. The insect has made up its mind to remount
the slope already so fatal to it. Perhaps it suits it to return to the
heights. Against that I have nothing to say, the Scarabæus knows better
than I do whether it be advisable to dwell in lofty regions. At all
events, take this path which will lead you up by a gentle incline. Not
at all. If there be near at hand some very stiff slope impossible to
climb, then that slope this wrong-headed insect prefers. Then begins
the labour of Sisyphus. With endless precautions the monstrous load is
painfully hoisted, step by step to a certain height, the beetle always
going tail first. One asks one’s self by what miracle of statics such a
mass can be kept on the slope. Ah! a clumsy movement brings all this
toil to naught. Down goes the ball, dragging the beetle with it. The
escalade is repeated, soon followed by a fresh fall. The attempt is
renewed, and better managed at the difficult points; a nasty
grass-root, which occasioned the previous tumbles, is prudently turned;
we have almost got to the top. But gently! gently! the ascent is
perilous, and a mere nothing may ruin all. A leg slips on a bit of
smooth gravel, and ball and scavenger roll down together. The beetle
