such as is soon TO illuminate all Fort
Worth, is said 10 have been strikugIy
| shown in Berlin in the spring of this
year. On some large lime trees, the
branches under the electric light dis
played new leaves of considerable size
while the buds on the opposite branches
where the light does not strike were only
just beginning to develop. The effect on
vegetation to result from the general
lighting of city may not be great
enough for one to note it. yet, If this
Berlin report be correct, Hqd the Berlin
scientists are seldom much tSff, our cleo
trio lights will really give Us an earlier

past.
The use of emery for grinding az poll

the past, it is supposed fine, hiSh-car-
bon steel tempered TO greatest possible
hardness, and then crushed IN powerful
stamp mill, is rapidly taking its place.
1t cuts stone and other substances more
rapidly than emery, and is said to be far
cheaper.

There is now reasonable promise that
electricity will soon be filling an i'm
portant office in the dairy. Professor q
Tolomei a noted Italian scientist, has
lately made some important tests. He
reports that when electricity was ap-
piled directly to fresh milk the sourlng
was delayed, sweetness being retained
from six to nine days, whereas q portion
OF the same milking not treated with
electricity was distinctly acid on the
third day. The electrified milk eOagu-
lated exactly like ordinary milk, and
not like milk that has been boiled, but
the coagulated milk had no acid quail
ties about it. He thinks milk might be
kept sweet year by repeating the cleo
trical application once in every three or
four days. The theory IS that electricity
destroys the germs that bring on the
acid condition.
Should this prove correct there exists
a strong probability that meats and other
substances liable to "spoil'' might be
preserved in the same waY. Possibly
the body of a deceased person might be
kept perfect for any time desired by a
repeated application of electricity.

have telescope of sixty inches diameter
and eighty feet in length, NJ. Camille
Flammarion saws: "To what unexpected
discoveries would this supreme effort OF
your great nineteenth century lead?
This is a question which it is impossible
to answer, but we have the right to
dwell on the word unexpected. 1t
must not be forgotten that 1t was when
searching for the limits of the colors in
the solar spectrum chat Fraunhofer dis
covered spectral analysis, and that it
was while seeking the parallax of the
stars that Sir William HerschelI discov-
cred the orbits of double stars, and it
was when seeking for Asia that Christie
pher Columbus discovered America In
any event, such a telescope will enable
us to see for the first time the seven
tenth magnitude stars, which must be-
over the depth of heaven in a
carpet of 8l8 900 900 stars, while the
moon will be brought, so to speak,
within touching distance.

In these notes We, hoping to interest
The young people, have had good deal
10 say about planets. The asteroids are
another grade of very small planets that
We have not heretofore found an occasion
'or mentioning. There are said to be 290
If them, all running on regular orbits
around the sun, but all too small to be
een with the naked eye. In recent
'ears there has been quite craze among
for hunting them, but now
he hunt seems to have been relinquished
o small group of specialists, one of
whom, NJ. Palissa, has detected no less
han seventy Of these tiny worlds in his
ixteen years of work. Mr.. Peters of
;linton, n. Y, has discovered forty
light; Mr.. Luther, twenty-fi five. in about
orty years, the brothers Henri-whose
attention is now absorbed in astronomi-
al photography-seven each, and NJ.

Professor F. W. Clark to have the fol-
