This is also well shown by the map, Plate 13. 



The great number and great strength of the N. W. winds at the top of Mount 

 Washington is another proof of the great mass of air which moves in this direction. 

 We have no observations during the winter on so high a mountain in the Southern 

 States, but it is probable that we should not find the N. W. winds as prevalent 

 there ; it is more likely that the W. or S. W. would be the most frequent. 



The mean direction of the winds in the four seasons is given in the following 

 table, and also in plates 8 and 11 : —

The much more southerly direction of the wind in the five last regions, belonging 

 to the S. Atlantic States, is seen at a first glance, while from New York to N. E. 

 Virginia it is more W. S. W. Everywhere it is between S. and W. in summer, 

 varying from nearly due south to nearly due west. The mean direction in the 

 spring is nearly the same as in the winter, somewhat to the southward. The ratio 

 of resultant is greater in the Middle and New England States than in the south, 

 both winter and summer, but especially in winter. 



A noticeable feature is the northerly direction in autumn in the South Atlantic 

 region. It is at least 2A° more northerly than in winter. This may be considered 

 as an approach to the trade-wind region. The belt of highest pressure on the 

 ocean has its most northerly position in September. As the indraught of air 

 towards the continent, which produced southerly winds in summer, ceases in the 

 autumn months, the air follows points of attraction further southward ; that is.
