The following table, compiled from the Monthly Weather Review 

 of the Dominion Meteorological Service, gives for the months of 

 January and July the average percentage of winds coming from 

 each point of the compass at several stations throughout the island :

The order of the weather changes during the approach of one of 

 these barometric depressions is almost invariable. After a period 

 of stationary barometer, accompanied by light winds, the mercury 

 starts to fall, the wind goes to the eastward with rain or snow, and 

 a period of thick, fogg\' weather sets in. About the time of lowest 

 barometer the southeast wind shifts to the southwest and then to the 

 northwest, blowing with storm force. The former shift is sometimes 

 sudden, the first squall often coming with extra violence, and ship- 

 masters lying off the coast should exercise corresponding watchful- 

 ness. The rise of the barometer is accompanied by overcast, squally 

 weather and storm winds from southwest to northwest, moderat- 

 ing and clearing about the time the mercury attains its highest point. 



The following extract from the log of the St. Georgios I, off 

 Cape Race, November 30-December 3, 1898, will serve to exemplify 

 the character of the weather changes in the southern semicircle of 

 one of these eastward-moving deiDressions. The Beaufort weather 

 notation is employed throughout:
