April 29th.—A light shock at Santa Barbara.
May 23d.—A shock at Crescent City.
May 31st.—An earthquake at Santa Barbara at 5h. 10m. In this earthquake there were three distinct waves. The first was accompanied by profound rumbling; the second shock was preceded by a loud, rushing noise like the approach of a strong wind. About four or five seconds elapsed between each shock. The sea was much disturbed, and a heavy surf swell came in soon after the second shock passed. This surf-wave rolled inland some thirty feet beyond the old wreck at the embarcadero. I saw the effect of this wave in July following. The inhabitants were much frightened and left their beds for the open air. Very little damage was sustained.
June 26th.—Two light shocks in Placer County.
July 10th.—One shock at Georgetown.
July 14th.—A shock at Georgetown.
Sept. 14th.—A light shock at Nevada.
Oct. 21st.—A light shock at Monterey.
Oct. 26th.—A smart shock at San Francisco, near midnight. It was felt at Benicia. This shock was followed by a swell in the bay, as vessels at the wharfs swayed heavily on their hawsers.
