I only read the preface and poems in this collection. The best of these are simply revelatory. I love how Hopkins uses rhythm as an expressive and dramatic tool. I'm amazed by his syllabic ingenuity. He plays with language and rhyme the way the best rappers do. This book has bars. 

The best of the best:

As Kingfishers Catch Fire
The Wreck of the Deutschland
Spring and Fall — "By and by, nor spare a sigh/Though worlds of wanwood leafmeal lie;"
The Bugler's First Communion — "Then though I should tread tufts of consolation/Days after, so I in a sort deserve to/And do serve to God to serve to/Just such slips of soldierly Christ's royal ration."
