Because they come from the southern regions, heated by the 

 hot earth and sands, and as they cross the sea they absorb a large 

 amount of vapour.

388. Why are clouds said to indicate the changes of the 

 weather ? 



Because, as it is the state of the clouds that, to a great extent, 

 determines the state of the weather, the formation of the clouds 

 must predicate approaching changes . 



389. What do cirrus clouds foretell ? 



Cirrus clouds foretell fine weather, when they fly high, and are 

 thin and light. 



They foretell light rain when, after a long continuance of fine 

 weather, they form fleecy lines stretched across the sky. 



They foretell a gale of wind when, for some successive days, they 

 gather in the same quarter of the heavens, as if denoting the point 

 from which to expect the coming gale. (Pig. 5). 



390. What do cumulus clouds foretell ? 



Cumulus clouds, when they are well defined, and advance with 

 the wind, foretell fin e weather.
