slight shocks imuiediately following the severe one, at intervals of ten or fifteen; 

 minutes. Subseiiuently earthquakes occurred on November 1 at 8:15 P. M.;. 

 November 2 at 9:50 A. m., and November 17 at 9:20 p. m. 



A good deal of injury to buildings is reported from Cairo, Illinois. At that 

 place there is reported to have been at least one shock each day during the first 

 five days of November. During one day there were three shocks. 



At Columbus, Kentuck}', the shock was sufficient to crack brick walls and 

 throw off plaster. As at Charleston the first shock was immediately followed by 

 two others of less intensity. One subsecjuent earthquake is reported for Novem- 

 ber 1 at 8:00 p. M. 



From nowhere else do the reports indicate such intense movement as at these 

 three places, and from no other place is there an earthquake reported subsequent 

 to the one of October 31st. As the three places are within a radius of twenty- 

 five miles, the epicentrum can be considered fairly well located. 



Reports from the Indiana gas field and vicinity indicate a movement slightlv 

 more intense than those from other parts of the State, but the increased force 

 was not sufficient to justify the conclusion that it was due to the removal of gas. 

 Three shocks in rapid succession are reported from Portland and Marion; two 

 from Decatur, (joshen, Lafayette and Frankfort. From other places only one 

 is mentioned. The average duration of the shock in six towns and cities within 

 the gas region was -14.1 seconds. The average duration of the shock in sixteen 

 towns and cities outside of the gas field was 43.2 seconds. That the apparent 

 increase of intensity within the gas region and vicinity is not necessarily due to 

 the removal of gas is shown in the reports from Bowling Green and Frankfort, 

 Kentucky, each of which announces three shocks. Frankfort and Indianapolis 

 are about an equal distance from the centre of disturbance. At Batesville, 

 Arkansas; West Plains, Missouri, and Nashville, Tennessee, the shock is reported 

 intense. At Wichita, Kansas, it was scarcely felt. At Atlanta, Georgia, it was 

 slight. 



Following the earthquake' were increased fiows of gas at Portland, Marion, 

 and BlufTton. There were increased fiows of water at Columbus, Shelbyville^ 

 Albion and Wabash. The water in Blue River rose several inches at Columbia 

 City. The water in Pigeon Creek, Warrick County, rose one and a half feet the 

 day following the earthquake, but soon subsided. Phenomena of this kind are a 

 common result of earthquakes. 



The average time of the shock as reported from Indiana was 5 o'clock, 10 

 minutes, and 30 seconds, A. M. There was nt> preceptible difference between the 

 time the wave was felt in the southern part and in the northern part of the State.
