his sight was clear, and he felt amazingly
refreshed and awake.
"Gladwin died several lifetimes ago"
said Wraite. "AS for Eva Pryor
Come" broke in Graemantle. There is
no time TO lose over recollectionS of your
Infancy! You had better 30 along with me.
IL will be a good way to get an idea at
once of The new conditions OF earth"
So, barely stopping to ciothe him in soft
silken garments and 10 give him draught
OF concentrated liquid food that seemed TO
make up, in jifry, for the missing nour-
ishment of centuries, he led him To an air
cutter. A short flight in this conve vance
!. bore them over the woods from the retire
ment OF the half-ruined laboratory to an
electric railway, where they bounded, as
though by magic, on to an electric train
moving at dizzy speed. The rest of the
journey Bemis scarcely realized, beyond
sensation OF being swept along as though
with the whizZ Of cyclonic wind. When
this ceased they were in Wisconsin, and
stepped offinto walking balloon which
proceeded with long strides OF its aluminium
legs over a slant of steep upland.
Here in Wisconsin, is the Penokee Range
OF mountains, chiefly remarkable for its
belt of iron ore, forty-three miles in length,
unbroken and very magnetic. This deposit,
averaging 800 feet IN width, extends to an
unknown unfathomed depth. IL was over
the magnetic ridge that they We're now
stalking. As Graemantle explained: 1t con-
taIns probably more iron than all the other
deposits of the United States combined:
but, ewing to the large admiXture of silicon
with the ore. " has never been utilized
1T occurred TO us that we might convert
the whole Fenokee iron deposit into a
gigantic magnet, by winding wire around
it. The Society of Futurity wanted to talk
with other planets; and to do this, we must
produce on earth magnetic disturbances Of
1 nad viz
duce them periodically, too; so that by
their force and their definite order of re
currence they would send shock through
vast distances, and compel the attention OF
dwellers on another sphere. Then they
might respond with similar movements,
which we could record on our magnetom-
eters; and SO we could start a conversa-
ton.
Look at that cleft in the range, right
under u.s. he added suddenly. That's
| Penokee Gap; and there's our station, with
| an engine of 5000 horse power. See those
! telegraph poles?"
Bemis looked, and beheld poles stationed
| like dumb sentrieS alongthe mountain sides,
| as far as the eve could reach Carving a
! great number of copper wires. There are
| 500 turns of that wire, " his new guardian
went on; ''and each turn is Sc miles in
length. They encircle this whole mountain
mass OF iron, which is their core, and make
! 1T colossal magnet, with which We do
our planetary telegraphing'
Alighting at the station, they met Prof
| Glissman, who was in charge-a small, ner-
vous man with elttering ewes that made
| him look as though he wore 4 pair OF spark
I ling Spectaclcs, or would like TO 10 30 If
| hlseyeS had not been so bright and piercing
without them. As he explained the great
! machine he punctuated his remarks with q

not seem much. But the engine drives his
| great dynamo here, which has an ar!nature
| wheel eighty feet in diameter and tie
| aFmature consists Of very fine iron wire
| chemically pure and slightly ONiGiZed over
which is wound copper Wire insulated by
/ Semi-vulcaniZed rubber.
| ''That surface is carried around att he rate
OF p, o0o feet a minute. The current lasts
/ only second or two: but il is sufficient TO
| bring our 800 eighty -siX-miie copper wires
! up to blood heat. Cast your eve, please =
here GlisSman coughed with humility 'on
| the gigantic switch at your elbow 1t is

and chooses the currentin six hundred places
simultaneously, and produces copper arc
seventy feet long
Then, with a fresh glitter of his peculiar
| eyes, he pointed out certain leather belts
! perforated on a definite plan, like JAG
| guard loom card. These belts governed
the motor and current controller constantly,
| with short intervals for return signals
The engines and dynamo" he said ''if
worked continuously, couldn't give more
| than 5000 horse power. But we do not
take electricity from the machine more than
| one-hundredth ufthetime Hence theenorm-
Gus potential energy of the fly wheel is
! capable OF "ausing current to be sent out,
which during lis brief periods equal to one

The experiment, Bemis was told, had been
| going on for some eighty-five years After
! fifteen years, the ma Enometer record Of the
| Penokee station suddenly showed-amid
the ordinary irregular motions registered
on it-a faint periodic motion similar to
the waves { was sending into space I'm
mediately GliSsman, who was then mere
child of thirty-one, reduced the period OF
sending waves from twenty hours o twelve
and thereupon the very same signals came
back from the unknown source and were
recorded on the ma gumeter here
Thus, by other variations. and by years of
toll, an alphabet ana mutual Language
were worked out. And at last" Grie
