n ~ ~ eta BILE for table use is the
Ora rnb& ta{1fia, an umbelliferous plant
ia kale. The sweet roots,
w. - cooked. are eaten by Tartars
ana e>ckackR and for these and the
Sprouts aSo, II Is recommended for Gull
uvxuon ps prominent member of the
Academie q Cuisine of Paris, who de-
clares tnatit Is finer in flavor than
asparagus All caulifower, which it
suggests. The rats are boiled In salt
water and seasoned In butter, salad
of young leaves and snees of roots be-
ing another dainty luxury.
Additonal particulars about tbe new
species OF white potato, which is, now
cultivated in France from plants found
in Uruguay, indicate that its import
ance as a substitute for the Irish po-
tato has not been exaggerated. Orig
inally very bitter tuber, the new veg
etable becomes, after three or four
years of cultivation, an admirable food
is exempt from the maladies that at
tack the ordinary potato. 1t grows
best in moist soil, its native habitat
being the marshy shores OF the River
Mercedes in Uruguay. Its flowers
have a jasmine-like odor, and a deli
cate perfume has already been extract
ed from them. After one planting the
plant perpetuates itself from the brok-
en- roots left in the soil.
Recent advances in the price of shell
lac, due partly to it's use in electrical
works and in making gramophone rec
ords, have led to the collection of facts
about its production. Lac is an in
crustation on the branches of certain
trees in India caused by insects. 1t Isl
found throughout India, but is most
abundant in the Central Provinces,
Bengal and Assam. 1t is collected by
natives, who break off the incrusted
branches. The gatherers and local
dealers sell 1t in the form of stick
lac" to manufacturers, who turn 1t
into the shellac, or button lac" of
commerce. Nearly the whole of the
shipment takes place from Calcutta,
and the chief markets are the United
States and Great Britain. In India
lac is made into bracelets, rings, beads
and other ornaments.
The apparatus by which DR.. Arthur
Korn, German inventor, has succeed
ed in transmitting photographs about
800 miles over telegraph-and-teleph
lines depends for its action upon the
changing electric resistance of seleni-
UNI under the influence of light OF
varying intensity. A ray of light,
caused to pass systematically over the
surface Of a transparent film contain
Ing photograph. falls upon seleDium
cell whose electric resistance varies
with the amount of light passing
through different parts Of the photo
graph. These variations are transmit
ted to the electric wire and at the re-
ceiving end they vary the illumination
Of small vacuum tube, which passes
over a sensitized Photographic paper
synchronically with the ray of light
moving over the film at the sending
station. Thus a copy of the original
photograph is produced.
Although the problem of color pho
Biography Is still far from solved, prog
ress Is being occasionally made. A
new German discovery-that of Dr.
Koenig-relates to printing from tri-
color negatives, and depends upon the
use Of paper coated with collodion So
buttons of colorless compounds of green
ish blue, cherry-red and yellow dyes
that develop the original colors on ex-
posture to light. The set of three mega
lives is first made under the usual light
filters. The printing paper is first
coated with the solution OF the dye
that is changed by light to greenish-
blue, and, after drying, 1t is exposed
about thirty seconds under the nega4
tive taken through the red filter. When,
the required depth of color is reached.
1t is fixed in a solution which removes
the unaltered dye compound. The pa
per is then recoated, this time with the
collodion for the red print, and ex-
posed in exact register under the green
negative. After this is fixed the third
coating is made, and the yellow image
is developed under the blue negative.
