ment is used in a public station or In a
private residence or business place. In
this case now decided, a telephone was
put in the appellants place Of business,
but it did not give satisfaction. The telo-
phone company was notified to TAX the
instrument out. This 1t did not do, but
caused the telephone to be adjusted, and
thereafter satisfactory service was OBJ
tanned. The lessee OF the instrument
wished to keep 1t then, but the telephone
corporation demanded payment for all the
time that the instrument had been in the
~lessee's place, regardless Of the time when
no satisfactory service could be obtained.
In reversing the decision Of the circuit
court the court held that the rule of the
telephone company not to replace a tele-
phone removed for non-payment Of rent
would not stand.
Novel telegraph Key.
Telegraph operators need suffer from par
alysis Of the wrist no longer II they will
use the key just invented by Charles Shir-
ley Of Al Sidney place, Brooklyn, reports the
Brooklyn Eagle. Mr.. Shirley has been
manager of the Postal company for several
years. His efforts to find a remedy for the
telegraph operators dreaded malady lost
grip" resulted In inventing this instru-
ment. 1t is a radical departure from the
telegraph key now in use, which has
afflicted so many operators with paralysis
and Operators writer's cramp. 1t is IN
tended to increase the speed of the opera
tor. It consists of a handle that may be
grasped by the whole hand or operated by
the touch OF any finger or part of the hand.
1t is unnecessary to retain a firm hold upon
this handle and the fingers may be shifted
as desired during transmission. 1t can be
turned completely around at will, so that
any desired position may be secured in
stantly. This little instrument brings into
action new and vigorous muscles which the
suffering telegraphers never knew they had.
Electric Waves from the Sun.
The London Electrician gives an abstract
Of the report of C. Nordman on his expert
ments at the Mont Blanc observatory for
the purpose OF finding out whether the sun
emits electromagnetic rays, or, rather,
whether such rays are capable OF penetrat-
ing to the surface of tho earth. OF course
it is reasonable to SUP pose that electro
magnetic waves Of the Hertzian kind are
actually sent out. In order to obtain the
best conditions It is necessary TO choose
the highest possible elevation, so as 20
escape the absorbing action Of the atmos-
pheIe anu OF aqueous NdpOT. Inc expert
ments, therefore, were conducted at the
station Of the Grands- Mufets, at an altitude
OF more than 5000 feet. A spell OF bad
weather prevented him from conducting the
experiments at the top OF Mont Blanc itself.
The receiver used consisted Of a g~alvano-
meter circuit with coherer and an antenna
175 meters long stretched over the Bosons
glacier. in such a position that at midday
the suns rays fell upon 1t vertically. This
had the double advantage Of protecting the
wire from the electric waves emitted by the
Chamounix railway and from the inter-
ference of waves which would have been
reflected by the ground IL the soil had been
a conductor instead OF a non-eondueting
glacier. The results of the experiments,
made under a cloudless sky on September
10, were entirely negative. The sun. there
fore. either does not send out waves OF this
order or they are absorbed by the suns at
mosphere or by the upper strata OF the
earth's atmosphere to such an extent thai
the registering device was not delicate
enough to record them.
Automatic Telegraph Systems.
Among all the problems which engage
the attention Of inventors. says the Boston
Transcript, there seems to be none more at
t~raetYe than that Of combining telegraph
