Forth of July turns calendar dates & birthdays into structural numbers. Thus May 29th : "Henry's" birthday, also RI Statehood Day, JFK birthday, day after Blackstone's burial, day after saint's day of Guillem de Gellone, Black Wednesday (5.29.1453), etc.

A bald list of such conjunctions seems rather meaningless. But the calendrical "rhymes" are elements in the construction of a narrative & thematic whole : "a 28 / nestled in 29". "Henry" represents the poet in a pattern of orphic returns or resurrections, a "ghost dance" for the American long poem, for the poet-suicides (Crane, Berryman - the author of the "Henry" Dream Songs), for Juliet (the poem is a "coming-forth of Julie"). That the entire poem is completed on 5.28 "fixes" the conjunction Blackstone/Henry/Rhode Island ("the rose" of Stubborn Grew/The Rose).

The structure of the central book of Forth of July, Grassblade Light, consists of 8-in-7 large chapter-panels, each consisting (with variations) of 28 sections of 28 lines each (7 quatrains), centered on a 29th section of 4x4 or 16 stanzas. The entire book is centered on a single stanza at the center of the doubled panel "Ghost Dance", in the following section:

28

 
As the whirring shape of a hummingbird
like a miniature bluejay overhead or
bee suspended over the clover
whispered

 
Love is our North Star high up above

 
I heard and
(as the rustling of that honey-mover
swelled across a grass-clay sheep-door)
lay in the sweet soil listening for your word.

                    
                        4.10.99 [note: Stubborn Grew, the previous book, 
                    was completed on 4.10.98, the year before]

Thus the entire poem is oriented at its center on the "North Star" (in Minnesota, the "North Star State", at the headwaters of the Mississippi) - which as this 28th section relates, represents the "tautology" (A = A) - Love/Word/Cosmos (explained a few days ago on this blog).
