The tide was slowly rolling in,
The air was grey and cold and thin,
The dog was dawdling and slow,
Beside the patch where wild leeks grow.
A block of polystyrene
Lay on the bank where slime, moss green,
And time and mud and paint thick drizzled
Made it into limestone, chiselled,
Hewn perhaps for the repair,
Of Selby Abbey, upstream, where,
Because the tides confuse the flow,
It had of course, already been.
And pondering where stone might float,
And debris making vessels, boats,
I was not then surprised to see,
A diplodocus, once a tree.
His jaws a branch which had diverged,
His body was in part submerged,
He swam along and kept apace,
And had a dolphin’s sense of fun,
But when I spoke made no reply
Yet seemed to crane his neck and turn his face
And wonder why,
I chose to walk and not to run.
