What differences there are in these running waters. We hear much of ‘blue’ rivers, of the silver flood of azure, and so forth. But few rivers or brooks or burns are blue. Their azure colour is a mirage wrought by distance and the angle of vision, affected by the play of wind, by the quality of light, by the blueness of the sky. Every German poet has sung of the blue Danube, the blue Rhine. These rivers have no quality of blueness, save by reflection from above, at a distance, and at a certain angle of vision. Waters flowing from the Lake of Geneva and from the Lake of Lucerne are blue even on grey days and if looked at on the shadow-side of a bridge. We have many grey-blue and blue-white and azure-shadowed running waters, but we have more that are grass-green and far more that are dappled hazel and nut-brown and golden-brown and amber-shot black-brown. It is not easy to say which of these running waters one loves best: nor need one, nor should one try. It would be like thinking of a garden-close filled with wallflower and mignonette, carnations and sweet-peas, dark violets and yellow pansies and blue love-in-a-mist, white tulips and lilies-of-the-valley and white roses, damask rose and the flusht morning-glory and the pink moss-rose and brier and eglantine, and saying which is best of these, which loveliest, which the most dear to the mind as well as to the eyes. But, still, we have doubtless each some happy choice, some hidden predilection. That will depend on memories and associations. I read somewhere recently that a certain traveller could not anywhere find, could nowhere recall, any stream or river for him so poetical, so lovely in quiet beauty as the Yorkshire Ouse. My knowledge of that river is restricted to a brief intimacy at and near York, and my recollection of it is of a broad turbid stream between muddy banks. But that does not interfere with the giving full credit to that traveller’s loyal affection. He would remember the Ouse among the sands of Egypt or by the yellow flow of the Hooghly or perhaps by the surge of some great river as the Mississippi, and it would flow through his mind in a serene pastoral beauty, bluer than any river that ever flowed in our grey North, and in a changeless light of May or June, with calling cuckoo and thridding swallow unmindful of seasons that come and go, and with green flag and tufted reed and trailing willow-branch as unfading as the memories to which they are for evermore wed. It would not be the Ouse that you or I look at from the muddy banks on a dull November day, or catch a glimpse of as the North Express whirls by. It would be the Ouse of boyhood and youth and the heart filled with a sweet trouble, perplext by a strange ache. It would be the Ouse at its loveliest, on a rare day, in an hour of the hours, flowing in midsummer-air fragrant with meadow-hay and wild-roses. It would be an Ouse more beautiful still: it would be subtly present in ‘the quiet
