Transcription: EARTHQUAKE. - On Saturday last, 3:9 [sic 3:09?] o'clock, p.m., was felt a severe shock of earthquake. We did not notice, particularly which way the earth vibrated, but, we are inclined to think that our hair took a decidedly upward tendency as the window rattled with the shock, which lasted about three seconds. Saturday was exrordingly [sic] warm, Sunday was quite cool, the sun being hid behind a thick cloud. About 10 o'clock, the wind sprung up from the westward and blew very heavily until 4:30, p.m., when it was lost in a shower of rain. Since the above was put in type we have been informed that the vibrations of the earthquake were from south to north, and that it was felt most distinctly by persons in the second story, or above the ground floor. There were 47-100ths of an inch of rain noted between Sunday and Monday morning.

Transcription: (Port Townsend) Prof. Dellisser's prognostication in regard to winds and earthquakes is being carried out to the letter - around "these parts" at least. The present has been one of the most extraordinary seasons for violent winds we ever experienced in this county. During the past week the wind has been blowing with unusual severity from almost every point of the compass; and rain and sunshine have been having a tilt, which, judging from appearances, is not yet decided.
