ttention of the road user. In Continental Europe this matter is
pretty well arranged, though there is frequently a discrepancy of
two, three, or even five kilometres between the national mile-stones
_(bornes kilometriques)_ and the sign-boards of the various local
authorities and touring clubs.

France has the best system extant of sign-boards and mile-stones. One
finds the great national, departmental, and communal signs and stones
everywhere, and at every hundred metres along the road are the
intermediate little white-numbered stones, from which you may take
your bearings almost momentarily, with never a fear that you are off
your track.

In addition to this the sign-boards of the Touring Club de France,
the Automobile Club de France, and the Association Generale
Automobile satisfy any further demands that may be made by the
traveller by automobile who wants to read as he runs. No such legible
signs and warnings are known elsewhere.

There is uniformity in all the kilometre and department boundary
stones in France; but in England "mile-stones" of all shapes, sizes,
materials, and degrees of legibility are found.

There are some curious relics in the form of ancient mile-stones
still in use, which may please the antiquarian, but are of no value
to the automobilist. There is the "eightieth mile-stone on the
Holyhead Road" in England, which carries one back through two
centuries of road travel; and there is a heavy old veteran of perhaps
a thousand years, which at one time marked the "_Voie Aurelian,_" as
it crossed Southern Gaul. It is found in Provence, in the
Bouches-du-Rhone, near Salon, and is a sight not to be missed by
those curiously inclined.

The question of dust is one of the chief problems yet to be solved
for the benefit of automobilists and the general public alike. A good
deal of the "dust nuisance" is due to badly made and badly kept
roads, but we must frankly admit that the automobile itself is often
the cause. "La Ligue Contre la Poussiere," in France, has made some
interesting experiments, with the below enumerated results, as
related to automobile traffic. Road-builders and manufacturers of
automobiles alike have something here to make a note of.

(1) Sharp corners and excessive road cambers lead to slip, and,
therefore, to dust.

(2) More dust is raised on a rough road than on an equally dusty
smooth road.

(3) Watering the road moderately diminishes the dust.

(4) The spreading on the r
