DAYS AND NIGHTS IN THE
MOON.
Their Wonderful Extremes Of
Heat and Cold.


London Times.
DIR. KLEIN. german astronomer. hal
recently called the attention of asfrono
, mers 10 lunar crater. some three mile,
wide, which ha~ not before been obsery
led. and which, he iecis sure. WAS not ii
existence two years ago. Astronomer,
have long since given up nll hopes o
tracing either the signs d; actual life
upon the moon or traces OF the past ex-
istencc ol living creatures there. But
there are still among them those who
believe that bv seduOus aud careful
scrutiny processes Of material change
may be recognized in that seemingly
inert mass. Ia reality. perhaps the
wonder rather j. that signs OF change
should not be often recognized, than
that from time 10 time new crater
should appear or the walls Of old craters
fall IN. The moons surface i exposed
10 variations or temperature compared
with which those affecting the surface
of our earth are altogether trifling. Ii
j. true there is no summer or winter in
the moon.
Sir W. IIerscheI has spoken Of the
lunar seasons a. though they resemble
our own. bnt ia reality they are very
different The SUM midday height at
any lunar station j. only about three de-
grees greater ia summer than In winter
whereas our summer sun i fortv-seven
degrees higher ia the sky az noon than
our winter ~un. In fact midsummer's
day on the moon does not differ more
from a midwintcr's day. as far as the
suns actual path on the sky j. concerned.
than with W. the 18th Of March differs
from the 25th. or the 18th Of September
from the 37th. Ii j. the change from
day "a night which chiefly affects the
moons surface. In The lunar year OIL
seasons. lasting 3a6 2-3 Of our days. each
lasting tweniy-ninc and three-quarters
of ours. Thus day lasts more than a
and j. followed by night OIL
equal length. Nor is this all. There Is
