Until, however, a number of properly equipped meteoro- 

 logical stations are established at high altitudes nothing 

 of a definite character can be known about our hill 

 climates. 



Dr. Shaw has suggested that the mean temperatures at 

 high altitudes might be ascertained by extra-polation from 

 lower stations, basing the calculations on the generally 

 established fact that the temperature falls V F. for every 

 800 feet. But this method does not enable the effect 

 of wind, which increases in force and frequency rapidly 

 with altitude, to be fully ascertained, and weather stations 

 could alone decide the actual conditions present. At the 

 present time, almost the whole of the meteorological 

 stations throughout the country are below the 800 feet 

 level, and consequently the climate indicated by systematic 

 observations extending over any lengthened period is that 

 of the low-lying and more or less sheltered lands. The 

 regular stations above this level reporting regularly to the
