For the remaining 75 to 100 yards, to the extreme left (n. w.) side 

 trees lay toward the east. Observations made at several different 

 points along the path of the storm showed that generally the trees on 

 the right (s. e.) side of the path had fallen in directions varying from 

 north to northeast, while on the extreme left (n. w.) side of the 

 track, their directions varied considerably. Over the section of the 

 path where the storm seemed to have assumed the form of a true 

 tornado, the trees, within a distance of from 100 to 200 yards from 

 the left side of the path, lay in directions varying from east to south- 

 east, and generally between 200 and 300 yards from that side, (about 

 the line of meeting between the whirling wind and the inflowing 

 current from the west) the trees lay more toward the south — while 

 over portions of the (.ath where there was little or no evidence of 

 the whirling movement, the trees lay toward the north or northeast. 



The "tornado centre," in every case where its position could be 

 determined, (as is usual in tornadoes) was found to be much nearer 

 the left (n. w.) than the right (s. e.) side. In the cross sections of 

 the path made at different points, the distance of the " centre " 

 from the left (n. w.) side, was found to be equal to one-third the 

 total width of the path. And in one cavse where there was no whirl- 

 ing motion of the storm, the line along which the two wind currents 

 met, as indicated by the position of trees and debris, occupied 

 about the same relative position as to distance from the two sides of 

 the storm path. 



One noticeable feature about the path of the storm, especially 

 that section over which the storm was most violent, was the evi- 

 dence of a strong wind having followed the tornado blowing in the 

 direction that the tornado was moving. Ov^er a space along which 

 must have been the tornado centre, varying in width from 100 to 

 200 yards, the trash, light timbers, and sand were piled up against 

 the southwest side of trees that had fallen across the track toward 

 the northwest. The soil in many places looked much as though it 

 had been washed over by running waters. Some heavy logs and 

 timbers appeared to have been rolled considerable distances toward 

 the northeast, after the trees had been blown down. The violent
