The effort which such momentary victories demand is almost superhuman; yet to possess the power to exert it is the sole condition upon which a poet may plunge into the world of phantasms. Mr Yeats has too little of the power to vindicate himself from the charge of idle dreaming. He knows the problem; perhaps he has also known the struggle. But the very terms in which he suggests it to us subtly convey a sense of impotence:—

Hands, do what you're bid;
Bring the balloon of the mind
That bellies and drags in the wind
Into its narrow shed.

The languor and ineffectuality of the image tell us clearly how the poet has failed in his larger task; its exactness, its precise expression of an ineffectuality made conscious and condoned, bears equal witness to the poet's minor probity. He remains an artist by determination, even though he returns downcast and defeated from the great quest of poetry. We were inclined at first, seeing those four lines enthroned in majestic isolation on a page, to find in them evidence of an untoward conceit. Subsequently they have seemed to reveal a splendid honesty. Although it has little mysterious and haunting beauty, The Wild Swans at Coole is indeed a swan song. It is eloquent of final defeat; the following of a lonely path has ended in the poet's sinking exhausted in a wilderness of gray. Not even the regret is passionate; it is pitiful.

'I am worn out with dreams,
A weather-worn, marble triton
Among the streams;
And all day long I look
Upon this lady's beauty
As though I had found in book
A pictured beauty,
Pleased to have filled the eyes
Or the discerning ears,
Delighted to be but wise,
For men improve with the years;
And yet, and yet
Is this my dream, or the truth?
O would that we had met
When I had my burning youth;
But I grow old among dreams,
A weather-worn, marble triton
Among the streams.'

It is pitiful because, even now in spite of all his honesty the poet mistakes the cause of his sorrow. He is worn out not with dreams, but with the vain effort to master them and submit them to his own creative energy. He has not subdued them nor built a new world from them; he has merely followed them like will-o'-the-wisps away from the world he knew. Now, possessing neither world, he sits by the edge of a barren road that vanishes into a no-man's land, where is no future, and whence there is no way back to the past.

'My country is Kiltartan Cross,
My countrymen Kiltartan's poor;
No likely end could bring them loss
Or leave them happier than before.'

It may be that Mr Yeats has succumbed to the malady of a nation. We do not know whether such things are possible; we must consider him only in and for himself. From this angle we can regard him only as a poet whose creative vigour has failed him when he had to make the highest demands upon it. His sojourn in the world of the imagination, far from enriching his vision, has made it infinitely tenuous. Of this impoverishment, as of all else that has overtaken him, he is agonisedly aware.

'I would find by the edge of that water
The collar-bone of a hare,
Worn thin by the lapping of the water,
And pierce it through with a gimlet, and stare
At the old bitter world where they marry in churches,
And laugh over the untroubled water
At all who marry in churches,
Through the white thin bone of a hare.'

Nothing there remains of the old bitter world which for all its bitterness is a full world also; but nothing remains of the sweet world of imagination. Mr Yeats has made the tragic mistake of thinking that to contemplate it was sufficient. Had he been a great poet he would have made it his own, by forcing it into the fetters of speech. By re-creating it, he would have made it permanent; he would have built landmarks to guide him always back to where the effort of his last discovery had ended. But now there remains nothing but a handful of the symbols with which he was content:—

'A Sphinx with woman breast and lion paw,
A Buddha, hand at rest,
Hand lifted up that blest;
And right between these two a girl at play.'
