Here we see illustrated the immense power which the direct 

 action of the sun exercises, a circumstance which, as Humboldt 

 long ago remarked, it is very necessary that we should always 

 remember to take into account when questions connected with 

 temperature are under consideration. Comparing one station 

 with the other we see that it is amongst the hills, where the air 

 is thinner and lighter than in the low country, that the direct 

 action of the sun produces the greatest effect; but then to 

 counter-balance this, the cooling process also goes on there with 

 the greatest rapidity. The average daily range of temperature 

 in the shade is not conspicuously different at the two stations at 

 any period of the year, but the fall upon the ground at night 

 below the minimum of the air is notably the least throughout 

 the year at the upland station, especially in Winter and Spring.
