I
When the clouds hide the sun away
The tall slate roof is dull and grey,
And when the rain adown it streams
'Tis polished lead with pale-blue gleams.
When the clouds vanish and the rain
Stops, and the sun comes out again,
It shimmers golden in the sun
Almost too bright to look upon.
But soon beneath the steady rays
The roof is dried and reft of blaze,
'Tis dusty yellow traversed through
By long thin lines of deepest blue.
Then at the last, as night draws near,
The lines grow faint and disappear,
The roof becomes a purple mist,
A great square darkening amethyst
Which sinks into the gathering shade
Till separate form and colour fade,
And it is but a patch which mars
The beauty of a field of stars.

It stands so lonely in the sky
The sparrows never come thereby,
The glossy starlings seldom stop
To preen and chatter on the top.
For a whole week sometimes up there
No wing-wave stirs the quiet air,
The roof lies silent and serene
As though no life had ever been;
Till some bright afternoon, athwart
The edge two sudden shadows dart,
And two white pigeons with pink feet
Flutter above and pitch on it.
Jerking their necks out as they walk
They talk awhile their pigeon-talk,
A low continuous murmur blent
Of mock reproaches and content.
Then cease, and sit there warm and white
An hour, till in the fading light
They wake, and know the close of day,
Flutter above, and fly away,
Leaving the roof whereon they sat
As 'twas before, a peaceful flat
Expanse, as silent and serene
As though no life had ever been.
