Though not a new thought. the superintendent of
the gas works at Cracow. Austria. has proposed a new
method designed to prevent the freezing of gas pipes.
According to this plan there Is employed n brass
cylinder. soldered upon the Eas main and containing
. basket OF chloride OF lime. The gas on passing
through the basket causes the chloride to deliquesco
and fall to the bottom of the box and there to liquefy.
tho liquid being drawn OF from time to time and the
chloride revivined by heating in a furnace TO drive

scope of this application; at any rate. It ia acknowl.

the effect of increasing its lighting and heating mower
and largely preventing rustinp and burrtinr Of tho
pipes during freezing weather.

The use of gasoline engines to operate mining ma
chinery has lately been discussed at n meeting OF
Ohio engineers, and in a very practical manner.
Heretofore the use OF the gas engine or machine
which emitted a blaze has been considered dangerous
in a mine, but It appears by the report OF the com.
mittee. on this occasion, that application of the same
TO coal mining in certain cases has now been made
and successfully; SO much so. indeed. as to promise a
positive rival Of steam. air. and electricity in mining
operations. An illustration of the comparative ad-
vantage in this respect is seen. for example, in the
case of q fan pump to be located one mile from
the power plant. There would be no conduct OF
steam to this 20 mt on account of the great condensa-
tion. With compressed air the friction would be
enormous; with electricity, while the loss by re-.
distance and leakage would be comparatively small,
constant watching Of the motor would be necessary.
Nothing Of this kind pertains to q gasoline engine.

Astronomers generally now admit that the more
recent studies Of the planets Mercury and Venus tend
to confirm Schiaparelli's opinion, advanced some
years ago. that both of them turn on their axes once
while revolving about the sun. This. however, is q
B very difficult point to settle with certainty, the rea.
son given for this being. and very plausibly. that the
evidence rests upon observation Of the exceedingly
J.; faint markings upon the disks OF the planets, the
4 fact being that very few astronomers have ever seen
them at all with distinctness, and only those who have
made q most persistent study of them and are favored
with vision especially sensitive to such details are
{ competent to express an opinion as to their correct
Interpretation. 1t is argued that II, rs held by some,
the rotation and revolution periods are the same be q
