| Townley and Allen repeat what Smith gives: "Portland. Reported as though localized in eastern part of Portland; rattled dishes, rocked chairs, disarranged books in cases, caused fright. Three shocks" and cite BSSA, 9, 68. 'Earthquake History of the United States' cites BSSA Vol. 53. These have not yet been checked. Newspapers also should be researched. |
