coins, all these have been spirited away.

Then there are the roads. Consider that great road which reached from
Amiens to the main port of Gaul, the Portus Itius at Boulogne. It is
still in use. It was in use throughout the Middle Ages. Up that road the
French Army marched to Crecy. It points straight to its goal upon the
sea coast. Its whole purpose lay in reaching the goal. For some
extraordinary reason, which I have never seen explained or even guessed
at, there comes a point as it nears the coast where it suddenly ceases
to be.

No sand has blown over it. It runs through no marshes; the land is firm
and fertile. Why should that, the most important section of the great
road which led northward from Rome, have failed, and have failed so
recently, in the history of man? Where this great road crosses streams
and might reasonably be lost, at its _pontes_, its bridges, it has
remained, and is of such importance as to have given a name to a whole
countryside--_Ponthieu_. But north of that it is gone.

Nearly every Roman road of Gaul and Britain presents something of the
same puzzle in some parts of its course. It will run clear and
followable enough, or form a modern highway for mile upon mile, and then
not at a marsh where one would expect its disappearance, nor in some
desolate place where it might have fallen out of use, but in the
neighbourhood of a great city and at the very chief of its purpose, it
is gone. It is so with the Stane Street that led up from the garrison of
Chichester and linked it with the garrison of London. You can
reconstruct it almost to a yard until you reach Epsom Downs. There you
find it pointing to London Bridge, and remaining as clear as in any
other part of its course: much clearer than in most other sections. But
