G. H. Luce. A Polar plain Doleful with crisp encrusted snows , Where if a morsel melt , a twinkle shows It straight is ice again . Those hoops of steel That gird and grapple mackerel skies , Which , as the outer impulse heaves and sighs , Swell and recoil and reel, Those gorgeous bars Have warped at last their brittle skein ; And from the rifted estuaries of rain And threshold of the stars, Deathless and stark And riveted with trenchant dew , Blossoms the flowery armour of the blue Beleaguering the dark . 106
