United States weather bureau out on oath
street. the old earth was again shaken
somewhere this morning. This latest
tremble comparatively slight in char
| acter as compared with the big quake of
yesterday. and may have been an after
shock of that disturbance, according to
Prof. c. F. Marvin the seismic specialist
of the weather bureau. It's time OF dura-
ton was from 6:33 to $40 o clock this
morning.
days quake was in any way re.ated to
that of yesterday, but he was inclined to
the belief that 1t was. The great shock
of yesterday, which scientists are trying
to locate. has heightened interest in seis-
mic matters, and the weather officials and
those of the coast and geodetic survey
have been besieged with inquiries since
it's occurrence. In this connection Prof.
Marvin said today that prior to two years
ago, before the great San Francisco disas-
ter, a shock like that Of yesterday would
not have attracted much attention. Now
the expectation is that severe shocks will
be associated with something disastrous
sooner or later after information is re-
ceived from distant points of the earth
Felt No Motion.
LAS / watched the pen of the seismo-
graph moving in a most violent manner

/ -
| of yesterday In the same class with the
| San Francisco quake. 1t was greater
than the Kingston shock, but the Mexican
| earthquake of last April and the Valpa-
raise shock of August, 1906. were both
greater than the San Francisco disturb
| ance or that of yesterday. The Kingston
| affair was the least intense of the recent
great earthquakes, according to the seis-
| mograph record.
! Tremors of the big quake of yesterday
are believed to have reached all quarters
! of the globe The needle of the seismo-
| graph at Johns Hopkins University, Balti-
more like that of the weather bureau in
| strument, was shaken entirely off the
| recording cylinder. The sesmograph of
| the State Museum at Albany. n. Y, could
| not record the full swing of the vibra-
| lions. The tremblings lasted for about
| one hour and forty-fve minutes. with a
!
| for four or five minutes.
| II is said to be the belief of some SCI
entists that no great harm has been done
| by the tremendous earth movement; that
| the earthquake was probably at the bot
| tom of the sea, several thousand miles
| from New York city. State Geologist
| Clark, having charge of the seismograph
| at Albany, indefinitely fixes the direction
| as south which would place the seat of
! the disturbance in the neighborhood OF
| Valparaiso, Chile, or southwest which
would locate 1t out in the Pacific ocean.
Near Bermuda-Maybe.
Prof. Harry Fielding Reid. at Johns
Hopkins University, noted that the most
violent tremor was at 9:13 am, and 1t
was during the eleven minutes following
| that the needle was repeatedly shaken off
the recording cylinder. The shock. he
! thought, was of about the same intensity
as that at San Francisco. and from an
| incomplete study of the tracings he
thought that possibly the center of dis
turbance was not more than 1000 miles
away, in the vicinity of Bermuda.
| II is regarded as unfortunate that Prof.
! Marvin was taken at a disadvantage at
| the time Of the occurrence of the shock
| yesterday. 1t was explained that the
| seismograph readings are made two
| Instruments, one recording the east and
| west movements and its companion the
north and south movements. A new in
| strument for north and south readings
was being installed at the moment of the
| first stock. ard the imprint paper had
| been removed from the companion instru-
ment
The replacing of the paper in the east
and west instrument consumed about
| ten minutes, and the needle did not begin
| its work until approximately OH m, or
seven minutes after the first tremor was
| recorded at Albany. when nearly all of
the preliminary tremors had passed
| 1t is upon preliminary tremors that the
| distance and direction of the disturbance
| are estimated, and therefore the govern
| ment's data of only the east and west
| tons is meager. The actual movement
| OF the earth is placed by the weather
| bureau at four-tenths of one inch, and
| the disturbance as one of the most Sc
| we're ever recorded there.
| The bureau has received no advices of
| an earthquake in any part of the world.
| and the officials believe that this quake
was probably in the Pacific ocean. Prof.
| Marvin believes tkat he Will be able from
his data to compute the distance.
In Interest Of Science.
The necessity for an interchange Of
seismographic data and reports be-
tween the United States and foreign
Prof. Marvin, and IL was said Con-
gress Will be asked at its next session
10 authorize the extension of the work.
| SO that this government may at least
get n reproduction of the records from
