At the first indication of its approach, people flee to their houses; doors and windows are shut and every crevice that could allow any dust to enter is tightly stuffed: while the wind lasts no one ventures out. Such unfortunate animals as happen to be overtaken by it have literally to struggle for their lives. The wind is not steady, but comes in fitful gusts, sometimes differing as much as 20° in temperature. The streets are deserted; and were they otherwise, a person could hardly be seen at a few yards distance. Hours pass: that implacable enemy, the dust, sifts in at unknown chinks. By degrees it covers everything. Valuable lace and tapestry are nearly ruined. You put on a skull-cap; yet it penetrates your hair. It finds its way beneath the garments to the skin, producing distressing dryness and roughness. The lips parch and crack. The eyes are red and inflamed. You drink as if famished, and gasp for breath. You are excessively irritable; you reach the verge of complete nervous prostration. At length the ordeal is over. You creep into the street, to find your neighbors looking like corpses; some, it may be, actually dead from nervous exhaustion. Dead birds and animals lie on the earth. It is a case of the survival of the fittest. You pluck a leaf from a neighboring tree; it crumbles to dust in your grasp.
Such are the effects of an unusually protracted wind, even when most favorably situated to encounter it. But if a caravan be overtaken by such in the desert, happy are they who escape. The camels kneel and thrust their

noses into the sand, against each other, into a pack of goods—anywhere to avoid breathing that poisonous blast. The men throw themselves upon the ground behind the camels, and muffle their heads in their garments. The storm is at hand; perchance attended by whirling columns of sand. You raise your head: a thick, dun-colored cloud flies at you; a heat as of red-hot iron, it seems, holds you in its choking grasp. You find your way to your water bottle, and drink deeply. The lurid sun turns the sweeping columns of sand to pillars of fire. Superstitious fear seizes your Arab comrades. Gradually the storm passes on: the men pick themselves up and endeavor to shake the irritating dust and sand from out the folds of their clothing, and the party resumes its way, happy that they are not numbered among the dead whose bones are bleaching by the way. Tales are not wanting of great caravans completely overwhelmed by the sandstorms of the desert.
These storms are met with in their greatest severity in Egypt and Arabia. In Egypt, this wind is called the Khamsin, or fifty, referring to the period of fifty days—the latter part of April, May, and early June—when they may be expected. They never blow through the entire season: rarely so long as fifteen days at a time. In Arabia the simoom may travel from the center of the peninsula toward any point of the compass; the Khamsin of Egypt blows from the southwest. Winds of the same character cross the Mediterranean. In Spain the wind is known as the Solano, or Levanter, or Leveche: in Sicily and Italy it is the Sirocco. The distressing dryness is somewhat modified by the journey across the Mediterranean. The same wind in Syria is called Samiel; and a similar wind which blows from the Sahara southwest to the Guinea coast is called the Harmattan. In California a similar dry hot wind blows from the interior toward the coast, during the hot season, and is called the desert wind. Such occasional hot blasts are experienced in southeastern Dakota, coming from the “bad lands,” or sandy and rocky wastes along the upper Missouri river.
