152 ON THE STORM EXPERIENCED THROUGHOUT THE UNITED STATES 



than the supply from the upper, and the tarometer began slowly to descend. 

 On the afternoon of the 19th the changes in the direction of the wind were 

 very slight. At Fort Brady the wind changed from north-east to south-east, 

 conforming now to the general direction of the winds in that quarter. 



On the morning of the 20th the barometric maximum passed through the 

 eastern extremity of Maine. The winds in the eastern states were accordingly 

 light, and exceedingly variable. At about half of the stations, however, the 

 wind was from the south, and at about one-half of the remainder it was south- 

 west. The irregularity at the remaining stations I ascribe to the lightness of 

 the wind, and to the fact that the influence of the barometric minimum at the 

 west was just beginning to be felt, but had not yet had time to impress upon 

 the winds any strong and steady impulse. On the southern border the winds 

 generally continue to blow from the north. The barometric minimum now 

 coincides nearly with the bed of the Mississippi river. Upon the west of this 

 line, the wind blows from the north and north-west; upon the east side it blows 

 from the east, south, and south-east. The winds in this section blow with 

 great strength, and their directions, as might be expected, are far more regular 

 and uniform. By the afternoon of the 20th the line of barometric minimum 

 had advanced farther to the east. The number of stations west of this line at 

 which the wind now blew from the north and north-west was increased. In 

 the eastern states the general direction of the winds was substantially the same 

 as in the morning. The wind at New Bedford and Halifax, the only stations 

 in this section at which, in the morning, it blew from the north, now blows from 

 ttie south. Oxford and East Hampton were the only stations, in the morning, 

 at which the wind blew from the north-west. At the former of these it is now 

 south, and at the latter south-west. On the eastern section of the storm the 

 wind now every where, with but a few trifling exceptions, blows from some 

 southern quarter. 



On the morning of the 21st the barometric minimum had arrived nearly at 

 New York city. In all the western and middle states the general direction of 

 the winds is from the west and north-west. At a few places it is north, and at 

 a few others south-west. But no where is it from the south, south-east, or east, 

 and at only one station, Jefferson Barracks, from the north-east. Even this 

 observation may be suspected to be a mistake, or must be ascribed to local 

 situation, when it is found that at St. Louis the wind was from the west. The
