Such feebleness of limbs thou provest,
That now at every step thou movest,
Upheld by two; yet still thou lovest,
My Mary!

And still to love, though press'd with ill,
In wintry age to feel no chill,
With me is to be lovely still,
My Mary!

But ah! by constant heed I know,
How oft the sadness that I show
Transforms thy smiles to looks of woe,
My Mary!

And should my future lot be cast
With much resemblance of the past,
Thy worn-out heart will break at last,
My Mary!

Even love, at least the power of manifesting love, began to betray its mortality. She who had been so devoted, became, as her mind failed, exacting, and instead of supporting her partner, drew him down. He sank again into the depth of hypochondria. As usual, his malady took the form of religious horrors, and he fancied that he was ordained to undergo severe penance for his sins. Six days he sat motionless and silent, almost refusing to take food. His physician suggested, as the only chance of arousing him, that Mrs. Unwin should be induced, if possible, to invite him to go out with her; with difficulty she was made to understand what they wanted her to do; at last she said that it was a fine morning, and she should like a walk. Her partner at once rose and placed her arm in his. Almost unconsciously, she had rescued him from the evil spirit for the last time. The pair were in doleful plight. When their minds failed they had fallen in a miserable manner under the influence of a man named Teedon, a schoolmaster crazed with self-conceit, at whom Cowper in his saner mood had laughed, but whom he now treated as a spiritual oracle, and a sort of medium of communication with the spirit-world, writing down the nonsense which the charlatan talked. Mrs. Unwin, being no longer in a condition to control the expenditure, the housekeeping, of course, went wrong; and at the same time her partner lost the protection of the love-inspired tact by which she had always contrived to shield his weakness and to secure for him, in spite of his eccentricities, respectful treatment from his neighbours. Lady Hesketh's health had failed, and she had been obliged to go to Bath. Hayley now proved himself no mere lion-hunter, but a true friend. In conjunction with Cowper's relatives, he managed the removal of the pair from Weston to Mundsley, on the coast of Norfolk, where Cowper seemed to be soothed by the sound of the sea, then to Dunham Lodge, near Swaffham, and finally (in 1796) to East Dereham, where, two months after their arrival, Mrs. Unwin died. Her partner was barely conscious of his loss. On the morning of her death he asked the servant "whether there was life above stairs?" On being taken to see the corpse, he gazed at it for a moment, uttered one passionate cry of grief, and never spoke of Mrs. Unwin more. He had the misfortune to survive her three years and a half, during which relatives and friends were kind, and Miss Perowne partly filled, the place of Mrs. Unwin. Now and then, there was a gleam of reason and faint revival of literary faculty, but composition was confined to Latin verse or translation, with one memorable and almost awful exception. The last original poem written by Cowper was The Castaway, founded on an incident in Anson's Voyage.

Obscurest night involved the sky,
The Atlantic billows roared,
When such a destined, wretch as I,
Wash'd headlong from on board,
Of friends, of hope, of all bereft,
His floating home for ever left.

No braver chief could Albion boast;
Than he with whom he went,
Nor ever ship left Albion's coast
With warmer wishes sent.
He loved them both, but both in vain;
Nor him beheld, nor her again.

Not long beneath the whelming brine
Expert to swim, he lay,
Nor soon he felt his strength decline,
Or courage die away;
But waged with death a lasting strife,
Supported by despair of life.

He shouted; nor his friends had fail'd
To check the vessel's course,
But so the furious blast prevail'd,
That pitiless perforce
They left their outcast mate behind,
And scudded still before the wind.

Some succour yet they could afford,
And, such as storms allow,
The cask, the coop, the floated cord,
Delay'd not to bestow;
But he, they knew, nor ship nor shore,
Whate'er they gave, should visit more.
