Yikes! Could someone help me find critiques on William Cullen Bryant?

I need four professional critiques on William Cullen Bryant for a project, and can only find one by Edgar Allan Poe. They can be about him, or, if need be, about a piece of his poetry. He's a relatively popular poet, so I'm not sure why I'm having a hard time finding critiques... Anything you could find or recommend would be beyond helpful. Thank you!
