Pale  beryl sky, with clouds	
Hued like dove's wing,	
O'ershadowing	
The dying day,	
And whose edge half enshrouds	        
The first fair evening star,	
Most crystalline by far	
Of all the stars that night enring,	
Half human in its ray	
What blessed, soothing sense of calm	        
Comes with this twilight,—sovereign balm	
That takes at last the bitter sting	
Of day's keen pain away.
