By casting the eye on the wood cut, it will be seen at a 

 glance that the wind blew on all sides towards the point of 

 greatest rain. 



But what is not a little remarkable, the wind was much 

 more violent all round the borders of the storm, than near 

 the centre. 1 At Harrisburg and Gettysburg it was gentle, 

 and at Emmettsburg it was tempestuous. It is true it did 

 not begin to be tempestuous till four o'clockj P. M., and at 

 Philadelphia it did not begin to blow very hard at the sur- 

 face of the earth, till about eleven, A. M. At seven, A. M., 

 it was very calm, though the low clouds were flying with 

 great velocity from the south east, exactly towards the 

 region of the great rain. 



1 It has since been ascertained that during the day of the 20th, the wind at 

 Silver Lake was so variable that it was difficult to know from what point it 



prevailed most.
