A relation between the character Of
dreams and the intensity of sleep has
been shown by the experiments Of N
vaschide. In profound sleep the
dreams refer to latent recollections of
long.past events and matters seeming
" having no connection with the pres
ent; but the dreams Of light slumber
are inspired by recent occurrences and
excitements, and are sometimes con-
nected with what Ii transpiring
around the sleeper.
Coal workings around Cheadle. In
North Stafrordshire. England, have
been traced back a. far as the reign
OF Richard III. The early mining 10
explained By local geological condi-
tions. as the coal-seams instead OF
being hidden under drift as In other
parts Of England-were brought to mo-
tice through dark streaks turned mp
by the plow. A late discovery is an
old level that must have been driven
at least three hundred years ago for
draining q coal tract.
After q series Of experiments with
carrier-p pigeons for conveying intslli-
gence. the German naval authorities
have decided to erect permanent pig
con stations on the coasts Of the North
and the Baltic seas. Every warshlp.
except torpedo-boats. leaving Kiel or
Wilhelmshaven win hereafter carry
consignment Of pigeons. to be released
at varying distances from the land sta
lions 1t is estimated that the birds
have sufficient endurance to fy home
over a distance Of about 1856 miles
from land.
After so much has been said OF the
excellence Of applied science In Ger
many. it il gratifying to leaEA from
Lieutenant Garden. who has returned
from an inspection Of the iron. steel
and machinery establishments Of Eu-
rope, conducted In the interests Of the
ST. Louis Exposition, that even In
German shops the high-grsde work is
done with American tools. For gen.
eral work. he says, German toolsshave
taken the place Of English tools,
which. ten years ago. were employed
in every shop Of Importance; but for
work requiring great precision and
excellence, there is to be found, In
nearly all the leading shops, group
Of American tools.
In the new fire-alarm system Of
Emile Guarini of Brussels, automatic
signals are sent to the engine house
by wireless telegraphy. The rise of
the mercury In q thermometer acts
upon a relay. and sets in motion a
wheel which makes and breaks the
electric circuit by series Of contacts.
A series Of impulses is thus sent
through an induction coil and the US
ual transmitting apparatus. The re-
ceiver at the central station or engine
house includes air and earth conduc-
tors, coherer, battery and Morse in
strument The same receiver can serve
a number of transmitters in different
places. and as the contacts on the
wheel can be varied, the exact location
Of the fire can be indicated.
