The observations at Cape Rosier and Father Point embrace 
only a period of seven months. A comparison o bh 
servations indicates a decided preponderance of high velocities 
at the more northern stations. In order to determine whether 
the force of the wind gene increases with an increase of 
latitude, I determined the mean velocity of the wind at all the 
ignal Service stations and classified the observations according 
to the latitude of the stations. The elaxig table shows the 
results at all the stations utiing of latitude 30°, except Mount 
Washington and Pike’s
