CLOUDS. 1 35 



Q. Why are these monster masses called 

 CUM'ULUS CLOUDS ? 



A. From the Latin word, cum'ulus (a 

 mass or pile). 



Q. Wliat do CUM'ULTTS clouds FORESHOW ? 



A. When these piles of cloud are 

 fleecy, and sail against the wind, they 

 indicate rain; but when their outline is 

 very hard, and they come up with the 

 wind, they foretell fine weather. 



Cumulus clouds should be smaller towards evening % 

 than they are at noon. If they increase in size at sun-set, 

 a thunder-storm may be expected in the night. 



Q. What are STA'TUS CLOUDS ? 



A. Creeping mists, especially preva- 

 lent in a summer's evening : these clouds 

 rise at sun-set in low damp places, and 

 are always nearer the earth, than any 

 other sort of cloud. 



Q. Why are these mists called STRA'TUS clouds ? 

 A. From the Latin word, stratus 

 ("laid low," or "that which lies low"). 



Q. How are the INTERMEDIATE CLOUDS sub- 

 divided ? 



A. Into two sorts. 1. The Cirro- 

 Cum'ulus ; and 2. The Cirro-Stra'tus.
