TABLES OF PREVAILING DIRECTION OF WINDS. 



125 



The following table gives the prevailing direction in each of the ten 

 States for the months indicated, as compiled from the returns, with the 

 ratio of northerly to southerly winds for each : 



*A dash signifies that the northerly and southerly winds for the month are about equal. 

 t Returns meager, and no southerly or northerly winds recorded, as the- case may be. 



As a brief summary of the information contained in the department 

 returns, in relation to direction, the following figures are given, showing 

 the prevailing direction of the winds for the cotton States, as a whole, 

 with the percentages of winds in each point of the compass for the 

 months named. The percentages are estimated per hundred observa- 

 tions : 



After the completion of the work on these returns it was thought ad- 

 visable to verify the statements by records of actual daily observation r 

 obtained from the Weather Bureau of the War Department, and at the 

 same time to make the report more valuable by taking into account,, 

 at the same time, the velocity of the winds, which has hardly been con- 

 sidered in the department returns, or indicated in too vague a manner 

 to be reduced to figures for tabulation.
