EDDY,s GIFTS TO SCIENCE.
Wonderful SeismOgrnphs and Cloud
Timers.

From the New York Sun.
Although a self-made scientist Will
liam Abner Eddy, kite-fyer, of Bay
own make that record tremors which
get by all other siesmographs on, earth
without making the slightest impress
sion.
Mr.. Eddy was referred to the other
day in an evening newspaper as the
inventor of the siesmograph, a deli
cate instrument for recording earth
quakes and earth tremors.
That's not exactly So" said Scien-
fist Eddy yesterday. The principle
of the sfesnoEraph was discovered
some years ago in Japan and a good
many instruments have been made and
used at scientific stations. But the
advantage of my improvements on the
instruments in use elsewhere is that
they will record more different kinds
of tremors than, for instance, the seis-
mographs on the Isle of Wight or at
Johns Hopkins University
Nobody would dispute Scientist Ed
DIV on that point after seeing the
siesmographs in his cellar and in his
front hall They'll even record the
rumble of a milkshake in any Bayonne
drug store south of Thirty-third street
Mr.. Eddy's house is a two-and-a-halt-
story frame structure in Bergen Point
and nostremors get by without shak-
ing it. IT. -
Two of these seismographs consist OF
long strings that might be used for
either fishing or flying kites, IL they
had not been devoted to science, Whlch
hang from the ceiling OF the top MOOT
down through the stair openings 10 the
ground floor To the lower end Oh each
string is tied boys spinning TOP, Inc
metal spindle of the tops rest llghtly on
two pieces of smoked glass. Thats the
makeup of the upstairs, or parlor'
saier3ooran mis-. Whenever the strings
swing or sway the top splhdieS HioNe
scratches on the smoked glass.
There's nothing to indicate the exact
time at which the scratches are mdue'
hut that Mr.. Eddy thinks, Is or minor
! inonortance. He looks ut the smokeu
| class every time he goes into the mouse
and if there is a. scratch ne hldhes "
memorandum of the fact in noIe pooh
and then calls up the newspapers ~
teIenhone and informs them that thete
has been an earthquake in the vicinity
If New York. Some of the papers al
ways print IT, ne1,, alto
But Mr.. Eddy does not IeiS 49,

sranhs in the hallway. They are 700 90

onened and there is any wind the sels-
,noeraphs make scratches so long tha az
