Passports in Germany.

FOREIGN OFFICE, Jan. 11.
Her Majesty's charge d'affaires at Munich reports
that a convention had been concluded between the
Governments of Bavaria, Saxony, Hanover, and
Wurtemberg, by which it is provided that travel-
lers, on entering or leaving the States forming part
of the association, shall be exempted from the obli-
gation of bearing passports.
Every traveller, however, whether native or fo.
reigner, is bound to furnish to the authorities, if
demanded, information as to his name and habitual
domicile, and also as to his means of subsistence, as
far as may be deemed necessary, according to the
object and duration of his intended stay.
The charge d'affaires further reports that the Go-
vernments of Baden and Oldenburg have declared
their willingness to adhere to this convention, the
stipulations of which came into force on the Ist inst.

A NEW ARTESIAN WELL.—To the two artesian
wells which Paris already possesses a third is now
being added, viz., at a point called Butte aux Cailles, in
the thirteenth arrondissement (Gobelins). The perfora-
tion has now reached the depth of eighty-two metres,
being twenty metres and a half below the level of the sea ;
but before reaching that point; considerable difficulties
have had to be overcome in the shape of intermediate
sheets of water, forming as it were a series of subterranean
lakes. The first of these was kept within its natural bed
by means of a strong iron tube driven perpendicularly
through it ; that which followed received wooden paling;
and the subsequent stratum being clay, the masonry was
continued without difficulty to a depth of five metres above
the sea level. But at this point a layer of agglomerations
was reached which let a great deal of water escape. It
thus became necessary to have again recourse to pumps;
those employed were in the aggregate of 20-horse power.
Owing to the bad nature of this stratum, it was resolved
to protect the perforation by a revetment of extraordinary
thickness ; and in order that the well might preserve its
diameter of two metres, the upper part has had to be
widened in proportion, so as to give it the enormous width
of forr metres at the top. After this labour the work
of perforation was continued through a stratum of pivo-
lithic limestone. At the depth corresponding to the
level of tho sea, they reached a layer of tubular chalk, all
pierced with large holes, forming so many spouts as thick
as a man's thigh, through which water poured into the
well with incredible velocity. While the pumps were at
work to get rid of this water, a cylindrical revetment
of bricks was built on a sort of wheel made of oak, and
laid down flat at the bottom of the perforation by way
of a foundation, and the intermediate space between this
cylinder and the chalk stratum was filled with concrete,
47,000 kilos. of which were expended in this operation.
As soon as the concrete might be considered to have set or
attained sufficient consistency, the brick cylinder was
taken to pieces again, and the perforation continued to thy
pressure point, where a new sheet of water has been
reached, requiring ingeniourf contriyanceo.
