To-night, a first movement, a pulse,

As if the rain in bogland gathered head

To slip and flood: a bog-burst,

A gash breaking open the ferny bed.

Your back is a firm line of eastern coast

And arms and legs are thrown

Beyond your gradual hills. I caress

The heaving province where our past has grown.

I am the tall kingdom over your shoulder

That you would neither cajole nor ignore.

Conquest is a lie. I grow older

Conceding your half-independant shore

Within whose borders now my legacy

Culminates inexorably.

II

And I am still imperially

Male, leaving you with pain,

The rending process in the colony,

The battering ram, the boom burst from within.

The act sprouted an obsinate fifth column

Whose stance is growing unilateral.

His heart beneath your heart is a wardrum

Mustering force. His parasitical

And ignorant little fists already

Beat at your borders and I know they're cocked

At me across the water. No treaty

I foresee will salve completely your tracked

And stretchmarked body, the big pain

That leaves you raw, like opened ground, again
