Communion with her visible forms, she speaks   

A various language; for his gayer hours   

She has a voice of gladness, and a smile   

And eloquence of beauty, and she glides   

Into his darker musings, with a mild   

And healing sympathy, that steals away   

Their sharpness, ere he is aware. When thoughts   

Of the last bitter hour come like a blight   

Over thy spirit, and sad images   

Of the stern agony, and shroud, and pall,   

And breathless darkness, and the narrow house,   

Make thee to shudder, and grow sick at heart;—   

Go forth, under the open sky, and list   

To Nature’s teachings, while from all around— 

Earth and her waters, and the depths of air— 

Comes a still voice—" (Thantopsis, Bryant)
In this little peice of one of his poems you can see how many times he uses personifications and how he uses very descriptive words to create imagery.
