WIND DIRECTION. 



The geographical position of the Islands on the southwestern edge of 

 the persistent area of high barometric pressure which covers the North 

 Atlantic Ocean causes a prevailing easterly wind throughout the year. The 

 group is on the northern edge of the reg-ular trade wind belt, in which there 

 is a steady flow of the atmosphere from the east, or the points between north- 

 east and southeast, with a preponderance of east winds. The relative fre- 

 quency of winds from the different points of the compass during the course 

 of the year is indicated in the following table of statistics covering a period 

 of five years.
