NO June day ever opened with a fairer promise. Not a single cloud flecked the sky, and the sun coursed onward through the azure sea until past meridian, without throwing to the earth a single shadow. Then, low in the west, appeared something obscure and hazy, blending the hill-tops with the horizon; an hour later, and three or four small fleecy islands were seen, clearly outlined in the airy ocean, and slowly ascen-ding - avant-couriers of a coming storm. Following these were mountain peaks, snow-capped and craggy, with desolate valleys between. Then, over all this arctic panorama, fell a sudden shadow. The white tops of the cloudy hills lost their clear, gleaming outlines and their slumbrous stillness. The atmosphere was in motion, and a white scud began to drive across the heavy, dark masses of clouds that lay far back against the sky in mountain-like repose.
