Everywhere, but far north in particular, the summer night has a loveliness to which the least sensitive must in some degree yield, creates a spell which must trouble even a dulled imagination, as moonlight and the faintest rippling breath will trouble unquickened pools into a sudden beauty. It is a matter of temperament, of mood and circumstance rather, where one would find oneself, at the rising of the moon, in the prolonged twilights of summer. To be in a pinewood shelving to a calm sea breaking in continuous foam: or among mountain solitudes, where all is a velvety twilight deepening to a green darkness, till the sudden moon rests athwart one hill-shoulder like a bronze shield, and then slowly is lifted and dissolves into an amber glow along all the heights: or on great moors, where one can see for leagues upon leagues, and hear nothing but the restless crying of the curlew, the screech of a heron, the abrupt unknown cries and fugitive sounds and momentary stealthy rustlings of nocturnal solitudes. Or, again, on a white roadway passing through beech-woods: or on a gorse-set common, with the churring of a nightjar filling the dusk with the unknown surge and beat in one’s own heart: or on the skirts of thatched hamlets, where a few lights linger, with perhaps the loud breathing and trampling of cattle: or in a cottage-garden, with mignonette and cabbage-roses and ghostly phlox, or dew-fragrant with musk and southernwood: or in an old manor-garden, with white array of lilies that seem to have drunk moonlight, and damask and tea-rose in odorous profusion, with the honey-loving moths circling from moss-rose to moss-rose, and the night-air delaying among tall thickets of sweet-pea. Or, it may be, on quiet sea-waters, along phantom cliffs, or under mossed and brackened rocky wastes: or on a river, under sweeping boughs of alder and willow, the great ash, the shadowy beech. But each can dream for himself. Memory and the imagination will create dream-pictures without end. Of all these midsummer-night creatures alluded to here or in the preceding article there may be none more allied to poetic association than the nightjar, but surely there is none more interesting than the owl itself, that true bird of the darkness. That phantom-flight, that silent passage as from the unseen to the unseen, that singular cry, whether a boding scream or a long melancholy hoot or a prolonged too-whoo, how blent they are with one’s associations of the warm husht nights of summer. But is not the nightjar also of the same tribe? Fern-owl is a common name; also jar-owl, heather-owl. I have heard it called the heather-bleat, though probably that name commonly indicates the snipe. How well I remember from childhood that puzzling riddle “_The bat, the bee, the butterflee, the cuckoo and the gowk, The heather-bleat, the mire-snipe; how many birds is that?_”
