stances, in the printed records of the Weather Bureau from which these 

 returns are made up. 



Beferring to the fifth table, we have an exhibit of the number of days 

 of perceptible winds from all quarters (without considering calms); the 

 prevailing direction for the month, and the percentage of prevailing 

 winds, calculated from the totals of actual days of wind for the month, as 

 above. 



A study of these tables reveals the fact that the prevailing direction 

 of the winds in the cotton States, as far as we are able to judge from 

 the thirteen stations, is almost without exception southerly for six months 

 of the year from March to August, ranging from 31 to 93 per cent. 

 Further, that the prevailing direction for the remaining months Feb- 

 rua IT, September, and October is quite variable. During the month of 

 February, however, southerly winds prevailed in Charleston, Savannah, 

 Lake City, Vicksburg, New Orleans, Indianola, and Galveston. In Mo- 

 bile the northerly and southerly winds were equal, and of the remain- 

 ing five stations, three indicate a northerly direction, and one, each, east 

 and west. For the month of September the winds are southerly at 

 Shreveport, Indianola, and Galveston, east at Key West, and northerly 

 at the remaining stations. The October winds at Vicksburg, Indianola, 

 and Galveston are southerly; at New Orleans the southerly and north- 

 erly winds are equal, and in the remaining States the latter direction 

 prevails. The highest percentage of northerly winds is 83 per cent, and 

 the lowest 35 per cent.
