A sapling must be hedged about for protection, but when it becomes a tree, a hedge would be a hindrance. So there is no need to criticise and condemn the old forms.
A tree there is that from its topmost bough
Is half all glittering flame and half all green
Abounding foliage moistened with the dew;
And half is half and yet is all the scene;
And half and half consume what they renew.
