Transcription: May 7. Yakima. Earthquake at Yakima.-- A correspondent, writing from Yakima, says that on the 6th ult., that vicinity was visited by an earthquake which was about as severe as the one in December, 1872. Some think it was harder. There were three shocks; the first was at half-past 3 o'clock, which lasted about eight or ten seconds, and made the houses tremble and creak sufficiently to frighten some persons quite badly and create an excitement among all the post. Five minutes later there was another light shock. The third shock, at fifteen minutes after 4 o'clock, was harder than the first, and lasted about twice as long.
