of the interior.
The icy torrents that hollowed it in the limestone have eaten away
rounded alcoves along the sides. On the white surface of these, glazed
over with a preserving film of stalactite, we at once notice the
outlines of many hands. Most of them left hands, showing that the
Aurignacians tended to be right-handed, like ourselves, and dusted
on the paint, black manganese or red ochre, between the outspread
fingers in just way that we, too, would find convenient. Curiously
enough, this practice of stencilling hands upon the walls of caves
is in vogue amongst the Australian natives; though unfortunately, they
keep the reason, if there is any deeper one than mere amusement,
strictly to themselves. Like the Australians, again, and other rude
peoples, these Aurignacians would appear to have been given to lopping
off an occasional finger--from some religious motive, we may guess--to
judge from the mutilated look of a good many of the handprints.

The use of paint is here limited to this class of wall-decoration.
But a sharp flint makes an excellent graving tool; and the Aurignacian
hunter is bent on reproducing by this means the forms of those
game-animals about which he doubtless dreams night and day. His efforts
in this direction, however, rather remind us of those of our
infant-schools. Look at this bison. His snout is drawn sideways, but
the horns branch out right and left as if in a full-face view. Again,
our friend scamps details such as the legs. Sheer want of skill, we
may suspect, leads him to construct what is more like the symbol of
something thought than the portrait of something seen. And so we wander
farther and farther into the gloomy depths, adding ever new specimens
to our pre-historic menagerie, including the rare find of a bird that
looks uncommonly like the penguin. Mind, by the way, that you do not
fall into that round hole in the floor. It is enormously deep; and
more than forty cave-bears have left their skeletons at the bottom,
amongst which your skeleton would be a little out of place.

Next day let us move off eastwards to the Little Pyrenees to see another
cave, Niaux, high up in a valley scarred nearly up to the top by former
glaciers. This cave is about a mile deep; and it will take you half
a mile of awkward groping amongst boulders and stalactites, not to
mention a choke in one part of the passage such as must puzzle a fat
man, before the cavern becomes spacious, and you find yourself
