"At about 4 o'clock yesterday morning a slight tremor of Mother
Earth was felt by several persons who happened to be out of bed at the
time. But the motion was so slight as to cause some doubt as to its
real character. At 22 minutes to six o'clock-one hour and 38 minutes
later on-there was a violent and unmistakable disturbance of the sublunary
sphere. The shock seemed to travel from east to west. -It was accompanied
by a loud rolling sound as if of a heavy cart being driven rapidly
through the streets, and ended with a bang! like the report of a cannon
fired a mile or two away. The force of the shock and accompanying noise
and clatter woke nearly everyone who chanced to be asleep at the time.
Houses rooked, crockery rattled, and doors and windows shook violently.
In some houses crockery was thrown from the shelves and broken. In
Langley & Co.'s drug store a number of glass chimnies were shaken from
the shelves and smashed. We have heard of no damage to persons or
dwellings. From New Westminster we hear that the shock was not felt
there."
