Calm is all nature as a resting wheel.  
The kine are couched upon the dewy grass;  
The horse alone, seen dimly as I pass,  
Is cropping audibly his later meal:  
Dark is the ground; a slumber seems to steal  
O'er vale, and mountain, and the starless sky.  
Now, in this blank of things, a harmony,  
Home-felt, and home-created, comes to heal  
That grief for which the senses still supply  
Fresh food; for only then, when memory  
Is hushed, am I at rest. My Friends! restrain  
Those busy cares that would allay my pain;  
Oh! leave me to myself, nor let me feel  
The officious touch that makes me droop again.
William Wordsworth
