the inside, when I heard or saw the
mule coming, and flattened myself against the wall.
I preferred the inside, of course, but I should have had
to take it anyhow, because the mule prefers the outside.
A mule's preference--on a precipice--is a thing to
be respected. Well, his choice is always the outside.
His life is mostly devoted to carrying bulky panniers
and packages which rest against his body--therefore he
is habituated to taking the outside edge of mountain paths,
to keep his bundles from rubbing against rocks or banks
on the other. When he goes into the passenger business he
absurdly clings to his old habit, and keeps one leg of his
passenger always dangling over the great deeps of the lower
world while that passenger's heart is in the highlands,
so to speak. More than once I saw a mule's hind foot
cave over the outer edge and send earth and rubbish into
the bottom abyss; and I noticed that upon these occasions
the rider, whether male or female, looked tolerably unwell.

There was one place where an eighteen-inch breadth of
light masonry had been added to the verge of the path,
and as there was a very sharp turn here, a panel of fencing
had been set up there at some time, as a protection.
This panel was old and gray and feeble, and the light
masonry had been loosened by recent rains. A young
American girl came along on a mule, and in making the turn
the mule's hind foot caved all the loose masonry and one
of the fence-posts overboard; the mule gave a violent lurch
inboard to save himself, and succeeded in the effort,
but that girl turned as white as the snows of Mont Blanc
for a moment.

The path was simply a groove cut into the face of
the precipice; there was a four-foot breadth of solid rock
under the traveler, and four-foot breadth of solid rock
just above his head, like the roof of a narrow porch;
he could look out from this gallery and see a sheer
summitless and bottomless wall of rock before him,
across a gorge or crack a biscuit's toss in width
--but he could not see the bottom of his own precipice
unless he lay down and projected his nose over the edge.
I did not do this, because I did not wish to soil my clothes.

Every few hundred yards, at particularly bad places,
one came across a panel or so of plank fencing; but they
were always old and weak, and they generally leaned
out over the chasm and did not make any rash promises
to hold up people who might need support. There was one
of th
