heats increase, but the thermometer rarely reaches 90° in the shade, and except in the narrow valleys the air is never oppressive. The autumn is generally very fine. Foggy mornings are common; but they are succeeded by bright pleasant days, without wind or rain. On the whole the climate is pronounced healthy, though somewhat trying to Europeans, who do not readily adapt themselves to a country where the range of the thermometer is as much as 90° or 100°. In the part of Media situated on the great plateau--the modern Irak Ajemi--in which are the important towns of Teheran, Isfahan, Hamadan, Kashan, Kasvin, and Koum. the climate is altogether warmer than in Azerbijan, the summers being hotter, and the winters shorter and much less cold. Snow indeed covers the ground for about three months, from early in December till March; but the thermometer rarely shows more than ten or twelve degrees of frost, and death from cold is uncommon. The spring sets in about the beginning of March, and is at first somewhat cool, owing to the prevalence of the _baude caucasan_ or north wind,a which blows from districts where the snow still lies. But after a little time the weather becomes delicious; the orchards are a mass of blossom; the rose gardens come into bloom; the cultivated lands are covered with springing crops; the desert itself wears a light livery of green. Every sense is gratified; the nightingale bursts out with a full gush of song; the air plays softly upon the cheek, and comes loaded with fragrance. Too soon, however, this charming time passes away, and the summer heats begin, in some places as early as June 18 The thermometer at midday rises to 90 or 100 degrees. Hot gusts blow from the desert, sometimes with great violence. The atmosphere is described as choking; and in parts of the plateau it is usual for the inhabitants to quit their towns almost in a body, and retire for several months into the mountains. This extreme heat is, however, exceptional; in most parts of the plateau the summer warmth is tempered by cool breezes from the surrounding mountains, on which there is always a good deal of snow. At Hamadan, which, though on the plain, is close to the mountains, the thermometer seems scarcely ever to rise above 90°, and that degree of heat is attained only for a few hours in the day. The mornings and evenings are cool and refreshing; and altogether the climate quite justifies the choice of the Persian monarchs, who selected Ecbatana for their place of residence during the hottest portion of the year. Even at Isfahan, which is on the edge of the desert, the heat is neither extreme nor prolonged. The hot gusts which blow from the east and from the south raise the temperature at times nearly to a hundred degrees; but these oppressive winds alternate with cooler breezes from the west, often accompanied by rain; and the average highest temperature during the day in the hottest month, which is August, does not exceed 90°.
