Proceeding northward, we approached the track of the showers, and, just before we Approach of a Tempest.--A violent Gale.--Misfortunes of an Irish Way- passenger 070 reached Wilbur's Basin, a cloud, black as Erebus, and so low that it seemed to rest upon the hill-tops, spread out above us like the wings of a monster bird; and in its wake huge masses of vapor, wheeling like the eddies of a whirlpool, came hastening on. The experienced boatmen understood these portents, and covering the baggage with strong canvas, lashed it tightly to the vessel. The breeze was still, and a hot, suffocating calm ensued. The passengers, warned by the helmsman, retreated into the cabin, and the windows were closed. The cattle in the fields huddled in groups, and every bird and fowl, conscious of impending danger, sought shelter. A flash of lightning, followed instantly by a crashing thunder-peal, broke over the valley, and seemed to sever the fetters of the wind. A sullen roar was heard in the distance, like the rush of great waters; the trees of the forest began to rock, and from the roads behind us clouds of dust arose and filled the air. In a few moments a tornado was upon us in its strength. It lasted only two minutes, but in its track the results of the labor of the farmer for many days were destroyed.
