are of the highest importance I manage daily to 



derive information which foretells the coming storm, and 

 would do so far more accurately had we two other stations 

 distant oue to three hundred miles." 



The hygrometer alone is a reliable instrument for de- 

 termining the weather some time in advance of a change. 

 On the mountain we could assure ourselves as to the 

 weather for twelve to twenty-four hours ; and after sum- 

 mer travel commenced our observations showed practical 

 results daily ; inasmuch as tourists stopping at the hotel 

 availed themselves of the information thus gained in 

 making their arrangements for the ensuing day. 



It is the hygrometer upon which we depend more than 

 the barometer. It is seldom that the readings of the wet 

 and dry bulbs differ more than four or five degrees, quite 

 rare that the difference is greater than ten. In this 

 country as great a difference as thirty-five degrees has 

 been recorded, and in India sixty degrees. I am led to 

 believe that however unfavorable the climate is, in some 

 respects, to health, the exemption from coughs and colds 

 is due to this uniformly moist atmosphere. 



THE WINDS. 



The records show almost constant and exceedingly high 

 velocities. Winds of from thirty to sixty miles an hour 

 are the rule, light winds and calms the exception. In 

 winter, ninety to one hundred miles is not uncommon, 

 while in summer it seldom rises to ninety. The winter 

 gales, which are westerly or northwest when attended by 

 a low temperature, spend their fury in a gentle north wind 

 bringing a moderation of temperature, quite frequently. 

 This has been noticed by Dr. Hayes, by McClintock and 

 Parry. I state the fact, but confess that I am unable to 

 explain the phenomenon. Here, as in the Arctic zone,
