Engraving on diamonds has been greatly de-
veloped within recent years. Using TOOLS OF MS
own invention Bordinet, the Paris jeweler. has
produced some very artistic work. and has sue
ceeded in polishing concave parts as well az
plane surfaces, and in modelling freely. One
specimen of his art is a yataghan having thin
diamond for blade and ruby for the handle
He has also cut pansy with leaves on large
diamond, made knife out Of two diamonds,
made beautiful bicycle with two diamonds for
wheels. cut one diamond in the shape of fish,
produced an exquisite brooch consisting OF q
beetle surrounded by sapphires and brilliants,
made other brooches in the form of flies with
thin engraved diamonds for wings. and cut ar
mortal bearings upon some gems. Mostremark-
able of all is ring Of diamond. with polished In
ner surface and outside finely engraved.

The Rhone near Bellegarde disappears for q
considerable distance In subterranean gulf
The engineers propose to change this interesting
geological feature by damming the river and
turning the water into two parallel tunnels,
which will lead the stream two miles and a half
to two power generating stations. Here fall
of nearly 200 feet will yield $4,000 horsepower
for 800 days in the year. The cost IL placed at
$5.0O00O0, and this use of the power is estimated

Biograph records are proving useful in show
ing the variations in disease as well as for medi
cal teaching. DR.. w. G.. Chase reports having
biographed q separate epileptic seizures and
one rare case of eye disease. Thrown upon q
screen, the enlarged pictures reproduce the
action of the muscles very clearly.

The automatic production of wire fencing in
continuous rolls is late development in cleo
trio welding. Galvanized wires are fed from
reels arranged vertically and parallel to each
other. and from another reel placed transverse
Iy to these are cut of lengths of wire, which are
fed horizontally across the vertical wires. At
the points of intersection of the horizontal and
vertical wires, Yields are made by means of small
forward regulated distance and the operation
is repeated.

Modern theories deal with various kinds of cor
puscles but none seem to be more unfamiliar
than those of odors. with which we have been
always surrounded. So little matter is given of
in odors that the balance cannot detect it, iodo-
form, for example, losing not more than thous-
andth part in a century. A French physicist, A.
Baldit, has found that the odor corpuscles affect
the leakage of electricity from electrified bodies
and he proposes to use this discovery for study
ing the character of odors and the part they play
in plants. In his experiments, performed in I'M
favorable weather, rod Of resin and an electro
scope were enclosed in glass jar. when the adj
mission of vanilla odor sensibly lessened the loss
Of electricity from the charged rod.

The use of furze in paper-making suggests
new class of materials to take the place of the
rapidly disappearing timber supply. On boiling
under pressure with caustic soda lye. treating
with sulphuric acid. bleaching with chloride of
lime and finally washing, the green plant is con-
verted into very white and solid pulp, which
has proven very suitable for paper making pur-
poses.
In the mountains of Panay and other islands
of the southern Philippines moths can be scraped
up by the quart. The natives have learned to
prize them as an article of food. and they now
collect and eat them in large quantities.

The efficacy of bomb-firing in breaking up hail
storms has been questioned. NJ Vidal, the origi-
nator of the plan, claims new evidence of its
value from recent severe storm that rapidly
swept down from the Bernese Alps through the
&I,ox dNrT 0kn
Leman as far as the Lake of Neuchatel. The
entire district was badly damaged by the hail,
except two small villages from which bombs
were thrown. 1t is pointed out that places
above 1900 feet in altitude escape damage. and
the low elevation Of the storm-clouds ensures
their breaking up by bombs and rockets, which
can be easily made to explode at heights of 1900
20 Tcc5 rect. 1t is urged that stations for bomb
firing be established along the usual routes of
the storms, the great damage done quite Justify
ing the expense.
The oxy-acetylene blowpipe, in recent tests,
has yielded temperatures high as 7,0000 f.,
while the oxyhydrogen flame gives only 3,6OO0 to
1900. cubic meter of acety lene was found to
develop about $1,000 British thermal units
against about 1900 for like quantity of hydro
gen. In Europe the oxy-acetylene blowpipe is

very satisfactory and economical for joining
tube plates up to half an inch in thickness, and
for repairs of tank and boiler plates. bicycle and
motor-car frames and much other work.

Asphaltine, a new paving material that is be-
ing tested in England and Germany, gives the
appearance of mosaic marble. 1t is mixture of
tar with iron Stag, is comparatively low in cost.
and has been found very elastic, tough and dur
able. 1t has resisted heavy traffic with no signs
OF wear.
Solid concrete cylinders, IL inches long by in
diameter, have been submitted by H. Woolson,
of Columbia University, to loads of 10000 to
10000 pounds The pieces were much compress
ed, the diameter being correspondingly increas-
ed, but there was no disintegration or powdering.
