nded by lines a little north of the
fortieth parallel and a little south of the thirtieth parallel. San
Francisco is just south of the fortieth parallel, while Naples is just
north of it. The latitude of Calabria, where the terrible earthquakes
occurred in 1905, is the same as that of the territory affected by the
recent earthquake in the United States. This may or may not have some
bearing on the question.

Whatever be thought of all this, one thing is certain, the earthquake
which laid San Francisco in ruins was felt the world over, wherever
there were instruments in position to detect and record it. The
seismograph in the government observatory at Washington showed that
the first wave, on April 18th, came at 8.19--equivalent to 5.19 at San
Francisco; that at 8.25 there was a stronger wave motion, and that from
8.32 to 8.35 the recording pen was carried off the paper. The vibrations
did not entirely cease until 12.35 P. M., during this period there
having been nearly half an inch of to and fro motion in the surface of
the earth.

RECORDS OF FOREIGN OBSERVATIONS.

From far away New Zealand, on the same date, the government seismograph
at the capital, Wellington, recorded seismic waves that apparently
passed round the earth five times at intervals of about four hours each.

Across the Atlantic, at Heidelberg, in Germany, the records showed
vibrations lasting one hour. At Sarayevo, in Bosnia, there was a sharp
shock at 11 A. M., undulating from west to east. At Funfkirchen, in
Hungary, at Laibach, in Austria, in the Isle of Wight, off the coast
of England, and all through Italy, from north to south, the shocks were
felt.

At Hancock, Mich., a shock was felt on April 19th a mile below the
surface in the Quincy mine of such severity that one man was killed and
four injured by a fall of rock loosened by the trembling of the earth.
There is no evidence, however, that this had any connection with the
California disaster, the dates not coinciding.

Turning to the Far East, across the Pacific, seismographs in the
Imperial University of Tokio showed that the earthquake was felt there
eleven minutes later than in San Francisco, and similar instruments in
Manila detected the arrival of the seismic waves twenty minutes after
the San Francisco shock. In this there was a slight difference in time
compared with Tokio, but, considering the distance, near enough to prove
that the disturbances came from the same source.
