stones being the more valuable, and
Consul IL. W. Harris, of Nurem berg,
reports that the known area contain
ing these stones is not more than 4
or miles long by 2 or wide. Ibis
little spot has supplied the worlds
photographic stones for more than
century, while the supply promises to
last at least one or two centuries
longer. The deposit is in layers of
half an inch to q or inches thick,
extending from the surface to
depth of 100 feet or more, and much
broken and worthless rock is contain
ed. Not more than one-twelfth of
the stone removed is mark eta BILE.
much OF this having small value on
account of the small sizes of the
clear pieces. The industry employs
1900 men, and the product goes to all
the civilized countries, the leading
buyers being Germany, France, Italy
and the United States in the order
named.
The curious toy motor of Lucien
tournier, lately awarded the grand
prize at a French exhibition, seems
at first to furnish energy from moth
ing. Over a shallow vessel is mount
ed horizontally an axle, with heavy,
SETTLING rod passing at right
angles through it, and the ends of
axle and rod are connected by cords
of hemp. When liquid is poured into
the vessel, the two lower cords are
soaked and shrink, forcing the rod
up. This raises the center of gravity,
and the upper end of the rod falls,
turning the axle and immersing the
other pair of cords. Evaporation re-
lakes the top cords, so that the rod Is
again pushed up. Slow rotation can
be thus kept up, and with several
rods and sets of cords, it can be made
fairly regular and continuous.
Late cancer research has shown
that the disease exists among all races
OF men, as we'll as in domestic and
wild ANIMALS, and that liability to it
is greatest in the last third of the
life span.
The art of the dyer is one of great
Importance in Persia, and the secrets
of special colors are carefully guarded
in certain families, and have been
handed down from father to son for
many generations. A warning to
would-be buyers of high grade
oriental rugs has been given by U. S.
Consul W. r. Doty, of Tabriz. A
proper guaranty that only vegetable
dyes and ixatives have been used
should be secured, for unknown ven
doris are almost certain to sell rugs
colored with chemical dyes, all OF
which-though there are different
qualltIes-are liable to change on
the first exposure to bright sunlight.
Since their first introduction about
1860, the use of coal-tar preparations
has been increasing, the cost being |
only one third or one.half as much |
as that OF the vegetable dyes The
cultivation of the madden plant,
which yields more than sixty of the i
finest shades of led and yellow, has
greatly declined in Persia, and the |
demand for the loot is now small. |
Between thirty and forty shades Of |
yellow are given by the shell of the
pomegrauate. Perhaps fifty varieties
Of blue are given by indigo; and for
the best blacks aud other coloring
material it is said that there are
employed hundreds Of herbs and |
varieties of bark, vegetables and even
some animal matter. Iron filings |

Powerful light rays is rapidly becom-
ing popular in Europe aud elaborate
equipments, costing up to $50, 900, are
being provided. A motor-car fitted |

Belgium. A London expert has dis
tributed fifty X.ray machines in En-

leading physicians are finding it de-
