Transcription: February 28, 1864 Victoria Daily Colonist, Victoria, B.C., March 14, 1864 "SHOCK OF AN EARTHQUAKE "We have received the following from a rural correspondent:--'The shock of an earthquake was felt on Thorne's Creek, three miles east of Fort Langley, on Sunday the 28th of Feb. last at 7 1/2, in the evening. It was accompanied by a hoarse thundering rumble, and lasted for about thirty seconds. The sky was at the time clear and brilliant and the atmosphere calm and mild. So frightful was the commotion of its quick and awful rockings as to make it a moment of great suspense as to whether the beholder would be buried with the log shanty, which cracked, rolled and tottered around him, in a conglomerated mass of hetrogenious ruin. Its course was across the Creek, from north to south.--Ib' "(Query. Has Artemus Ward strayed up to the neighborhood of Thorne's Creek?--Ed. ) "
