| Transcription: 1872- On the evening of December 14th, occurred the most severe earthquake ever experienced in the Puget Sound region. Buildings and trees swayed, clocks stopped, shelf articles were thrown down and people were quite alarmed. On made land, and structures on piles the stock was greater or more felt than elsewhere. Three evenings later the earth again quaked, but less violently. |
