Two shocks at Roseburg
First was felt Tuesday night at 10.
Soon after 5 yesterday morning guests at Hotel in Glendale were aroused.
Roseburg, OR., April 18--(Special)-- Distinct vibrations of an earthquake were first felt in this place last night about 10 o'clock. The vibrations seemed to go from southwest to northeast. The second earthquake was felt this morning a little after 5 o'clock, when it was noticed by W.H. Fisher and others. It was also distinctly felt in Glendale, where it awakened guests in the hotel and elsewhere distinct shocks were felt.

Pictures Moved on Walls
Marshfield, OR., April 18--A slight earthquake was felt here early this morning. No damage resulted, but the shock was sufficient to move pictures on walls. One clock was stopped at 5:20 AM.

Buildings Swayed at Grant's Pass
Grant's Pass, OR., April 18--(Special)-- An earthquake shock was felt here at 5:25 this morning. It lasted a full minute and the motion was from north to south. It was strong enough to swing doors and make buildings sway perceptibly to those who were awake, but not sufficient to arouse sleepers. It was the heaviest shock ever felt in Rogue River Valley.

Tremors felt at Ashland.
Ashland, OR., April 18--Earthquake shocks were felt here about 5 o'clock this morning, which in point of time correspond with the great earthquake at San Francisco. Distinct disturbance of the earth was felt, which could be slighted to no other source.
