From Impatience to Nap

Chaps, here's a book
It's shorter than what you're used to
And it's used, wouldn't know new
If it got hit in the bricolage
As assemblies go, these parts came 
Made to order
From the anvils and crucibles 
Of eons, in years
There will be another song
As the assemblage
Glue string letters-pressed
Make a new block
That will build the structures 
Of a heavier future
