In the map the small white 'A' shows where the railway bridge was, and
in this map, as in the others, the dark is for the depth and the light
is for the heights. As for the picture, it is what one sees when one
is coming over the ridge at the north or top of the map, and when one
first catches the river beneath one.
I thought a good deal about what the Romans did to get through the
Mont Terrible, and how they negotiated this crook in the Doubs (for
they certainly passed into Gaul through the gates of Porrentruy, and
by that obvious valley below it). I decided that they probably came
round eastward by Delemont. But for my part, I was on a straight path
to Rome, and as that line lay just along the top of the river bend I
was bound to take it.
Now outside St Ursanne, if one would go along the top of the river
bend and so up to the other side of the gorge, is a kind of subsidiary
ravine - awful, deep, and narrow - and this was crossed, I could see, by
a very high railway bridge.
Not suspecting any evil, and desiring to avoid the long descent into
the ravine, the looking for a bridge or ford, and the steep climb up
the other side, I made in my folly for the station which stood just
where the railway left solid ground to go over this high, high bridge.
I asked leave of the stationmaster to cross it, who said it was
strictly forbidden, but that he was not a policeman, and that I might
do it at my own risk.
