Need help in comparing thistles and Where the picnic was

Comparing what? Gist, rhythm, rhyme, form, theme?


Where the Picnic Was

Where we made the fire,
In the summer time,
Of branch and briar
On the hill to the sea
I slowly climb
Through winter mire,
And scan and trace
The forsaken place
Quite readily.

Now a cold wind blows,
And the grass is gray,
But the spot still shows
As a burnt circle -- aye,
And stick-ends, charred,
Still strew the sward
Whereon I stand,
Last relic of the band
Who came that day!

Yes, I am here
Just as last year,
And the sea breathes brine
From its strange straight line
Up hither, the same
As when we four came.
-- But two have wandered far
From this grassy rise
Into urban roar
Where no picnics are,
And one -- has shut her eyes
For evermore
- Thomas Hardy


Thistles

Against the rubber tongues of cows and the hoeing hands of men
Thistles spike the summer air
And crackle open under a blue-black pressure.

Every one a revengeful burst
Of resurrection, a grasped fistful
Of splintered weapons and Icelandic frost thrust up

From the underground stain of a decayed Viking.
They are like pale hair and the gutturals of dialects.
Every one manages a plume of blood.

Then they grow grey like men.
Mown down, it is a feud. Their sons appear
Stiff with weapons, fighting back over the same ground.
-- Ted Hughes
