SOUTHERN BORDER OF CENTRAL COAL FIELD. 



TEMPERATURE. 



The temperature of a district is dependent largely upon the altitude and 

 latitude. As the question of temperature is one that is to be considered in 

 determining the adaptability of a country to agriculture, a table of the tem- 

 perature is here given, the observations having been made at Fort Concho: 





January. 



February. 



March. 



April.

It must be remembered in consulting the above table that the high tem- 

 perature shown does not produce the same effect upon vegetation or animal 

 nature that the like temperature would produce at a lower altitude and one 

 where there was little breeze. In this country the atmosphere so rapidly 

 absorbs the moisture of the body that the heat is not as oppressive as where 

 the absorption is not so great. Such a thing as sun-stroke has never been 

 known in this part of the State.
