We see that the center of low pressure generally passes north — 
of Pike’s Peak, and there are only six cases in which the low — 
was south of Pike’s Peak, viz: Nos. 1, 8, 9, 22, 23 and 26. 
In the case of Nos. 1 and 22 the wind on Pike’s Peak was © 
northeast; in No. 23 it was from the south; in No. 26 it was © 
calm ; in No. 8 it was southeast at the time of the last preced- _ 
ing observation ; in No. 9 it was southwest and had been blow- 
ing from some western quarter for a period of forty-eight hours. 
The first five cases accord tolerably well with the results found — 
for the winds on Mt. Washington, but No. 9 seems to indicate 
ee the system of circulating winds which prevailed at that 
te at lower stations did not extend as high as Pike’s Peak. 
We see that one reason why easterly winds are so rare on Pike's ~ 
Peak, particularly during the winter months, is that the low 
centers generally pass north of that mountain. 
receding investigation seems to warrant the following — 
conclusions, which are an extension of those stated on page 19. — 
1. At the height of 6,000 feet the winds circulate about cen- — 
ters of low pressure as they do near the level of the sea, but 
frequently the position of the center of low pressure is sensibly _ 
different at the height of Mt. Washington from what it is at
