Attention has been called to the fact
that the streams In certain cultivated
nortions OF northern Texas now run
during the part of the year when they
were formerly dry. This is not attrlo-
uted to any change in the rsSnfall, but
to a more even absorption OF water over
the cultivated areas.
In Japan, according to a Government
report. 5S3 earthquakes occurred during
the nine and half years preceding De-
cember. 1884. The record is evidently
incomplete, however, as Prof. Milne
has been able to trace an average of an
earthuuake a day in Nsgsski, in the |
extreme south Of Japan.

A meteorological station is about TO
be established among the highest noun
tains of Mexico, at an altitude OF near
ly2O,OOO feet above the sea level. AS
access to such a place is difficult and
often impossible, the recording appara-
tus will have to be made almost indie
pendent of human attention, and, as
far as possible, all the instruments will
be made to run year without stepping.
French experiments on the the trans
mission of power by electricity have re-
suited less successfully than was hoped.
Theoretically the plan is feasible, but
it is found to be more economical and
practicable for manufacturing purposes
to use the power directly at the source
OF supply. Modern railway facilities
make It cheaper to transport goods than
power, with its attendant loss OF fifty
per cent.-not to mention It's uncertain.
