like a gentleman, he has his hands free to scratch his ribs or twitch
his moustache. And when he goes he needs not to put them to the ground,
for his great tail so nearly equals the weight of his body that one pair
of legs keeps the balance even. And so the kangaroo, almost the lowest
of beasts, comes closer to man in his postures than any other. The
squirrel also sits up and uses his forepaws for hands, but the squirrel
is a sybarite who lies abed in cold weather, and it is every way
characteristic of him that he has sent his tail to the furrier and had
it done up into a boa, or comforter, at once warm and becoming. See,
too, how daintily he lifts it over his back to keep it clean. The rat is
a near relation of the squirrel zoologically, but personally he is a
gutter-snipe, and you may know that by one look at the tail which he
drags after him like a dirty rope. Others of the same family, cleaner,
though not more ingenious, like the guinea-pig, have simply dispensed
with the encumbrance; but the rabbit has kept enough to make a white
cockade, which it hoists when bolting from danger. This is for the
guidance of the youngsters. Nearly every kind of deer and antelope
carries the same signal, with which, when fleeing through dusky woods,
the leader shows the way to the herd and the doe to her fawn.

But of beasts that graze and browse, a large number have turned their
tails rather to a use which throws a pathetic light on misery of which
we have little experience. We do, indeed, growl at the gnats of a summer
evening and think ourselves very ill-used. How little do we know or
think of the unintermitted and unabated torment that the most harmless
classes of beasts suffer from the bands of beggars which follow them
night and day, demanding blood, and will take no refusal. Driven from
the brow they settle on the neck, shaken from the neck they dive between
the legs, and but for that far-reaching whisk at the end of the tail,
they would found a permanent colony on the flanks and defy ejection,
