Thus we see that. 60 per cent of all the high winds came from 
the northwest ; 75 per cent came from the west and northwest; 
87 per cent came from the west, northwest and north; while 
only 4 per cent came from the northeast, east and southeast. 
In order to determine whether these high winds bear a con- 
stant relation to centers of low pressure as indicated by obser- 
vations near the level of the sea, I prepared a table showing 
for each date the position of the nearest center of low pressure. 
This table is so large that I have not thought it expedient to 
publish it entire, and I have endeavored to abridge it in such a 
of velocity for each direction of the wind. For the northwest 
winds I have employe only velocities a at one hun lre d 
miles per hour; for the west wind, I have employed velocities of 
Mount Washington there was generally a Jow center near Hali- 
fax, Sydney, Quebec, Father Point or Cape Rozier. In the 
case of No. 88 (which is the continuation of No. 11) the low 
“enter had already passed beyond our stations of observation.
