to occur in November. Tliey should therefore be given 

 Weather Record, Ko. II., with its spaces, not only for 

 the daily record of the wind, its direction, and force, but 

 also for the names of the clouds. Instead of writing the 

 names in full, they might now use the proper abbrevia- 

 tions, which are as follows : 



Cumulus .... cu. 



Stratus s. 



Nimbus .... n. 



Cirrus ci. 



Mixed clouds, such as strato-cumulus, have for their 

 abbreviation a combination of the two, in this case s. cu. 



The teacher, at least, should now begin to watch the 

 clouds with reference to their indications of future 

 weather. She herself can best judge when is the appro- 

 priate time to teach what she learns, but certainly she 

 should learn sometime during the year the following 

 facts : 



The commonest cloud form in summer is the cumulus. 

 In Avinter stratus and cirrus clouds prevail. In autumn 

 cirro-cumulus and alto-cumulus are most frequently seen ; 

 and in spring cirro-stratus and cirrus. 



Slowly moving cirrus clouds indicate a probable slight 

 change in temperature. If they are moving rapidly 

 along, the chances are in favor of a decided change. 

 This is likely to be a fall in twenty-four hours, espe- 

 cially when the wind is from the southwest. When the 

 wind is northwest, on the contrary, there is likely to be 

 a rise in temperature within twenty-four hours. 



With cirro-stratus clouds there is some probability of 

 rain; with alto-cumulus and alto-stratus, the likelihood 

 is greater. Cirro-cumulus clouds indicate fair weather.
