Very hard. 



Stormy. 



Hurricane. 



The first ranges from the slightest motion in the air, to about 

 that degree of force required to raise a flag to about an angle of 45° 

 with the staff. 



The second continues from that, until the flag flies parallel to 

 the earth. 



The wind is " stiff," when it offers material resistance to proceed- 

 ing against it. "Hard" when the trees bend and groan under it. 

 "Very hard" when green leaves are stripped off the trees, and all 

 light articles on the ground are whirled up in the air. " Stormy" 

 when branches are torn from the trees, and these themselves, when 

 with no depth of root, prostrated. And a " hurricane" there can 

 be no mistaking. 



In observing the clouds, I have only written down the predo- 

 minating form of cloud visible at the time. 



When "nimbus" is recorded, it was positively raining at the time 

 of observation.
