Read the poem by Kenneth Slessor then answer the questions.
Wild Grapes
The old orchard, full of smoking air,
Full of sour marsh and broken boughs[1], is there,
But kept no more by vanished Mulligans [2],
Or Hartigans, long drowned in earth themselves,
Who gave this bitter fruit their care
Here's where the cherries grew that birds forgot,
And apples bright as lone stars; now there is not
An apple or a cherry; only grapes,
But wild ones, Isabella grapes they're called,
Small, pointed, black, like boughs of musket-shot.
Eating their flesh, half-savage with black fur.
Acid and gipsy-sweet, I thought of her,
Isabella, the dead girl, who has lingered on
Defiantly when all have gone away,
In an old orchard where swallows[3] never stir
Isabella grapes, outlaws of a strange bough,
That in their harsh sweetness remind me somehow
Of dark hair swinging and silver pins,
A girl half-fierce, half-melting, as these grapes,
Kissed here - or killed here - but who remembers now?
[1] Mulligans/Hartigans – Irish last names
[2] Boughs – main branch of a tree
[3] Swallows – small birds
What is the significance of the 'old orchard'?
