THE CALM. 



The waves are asleep ! sweetly calm is their 

 rest, 



The pearl-beds of ocean are silently press'd ; 

 'ihe crimson- wing' d light, from the western 



sky beaming, 

 O'er the slumbering waters is brilliantly 



gleaming ; 

 The Nautilus floats like a fairy along. 

 No sound, save the mariner's love-burthen'd 



song, 



Or the soft curfew-bell, meets the listening 

 ear — 



The earth and the heavens to each other draw 

 near. 



The sea covers nearly three- 

 fourths of the globe. When the 

 atmosphere is still, the sea is 

 calm, 3 ; but when heat or cold, 

 by disturbing the equilibrium 

 of the atmosphere, causes it to

 municates motion to the sea, 

 producing what are called waves,

THE BREEZE. 



The waves are awaking, their myriads rise, 

 The rays of the morning illumine thnr eyes ; 

 Their crests are all white, and their voices 

 begin 



To speak of the battle, with murmur and din ; 

 They are woo'd by the winds, and the troth of 

 the pair 



Was never excell'd by the loves of the fair. 

 There are legions advancing, and legions have 

 gone, 



And legions unnumber'd ride carolling on.

THE STOEM. 



The waves they are raging, their fury is high, 

 They leap in tbeir wrathfulness up to the sky ; 

 They lash the wild shore, and an echoing 

 moan 



Is heard where the sway of the ocean is known.
