Along the south coast of the Caspian this line of elevation is prolonged as the Elburz range(not to be confused with the Elburz of the Caucasus), and has its culminating point in Demavend, which rises to 19,400 ft.
To S.E., the second section of the Elburz begins, and extends from there to beyond Mount Demavend, east of Teheran.
And Mount Demavend in the N.E., are the ranges Azadbur, Kasil, Kachang, Kendevan, Shahzad, Varzeh, Derbend i Sar and others, with elevations of 12,000 to 13,500 ft., while Demavend towers above them all with its altitude of 19,400 ft.
The eastern foot of Demavend is washed by the river Herhaz (called Lar river in its upper course), which there breaks through the Elburz in a S.-N.
(Russian trigonometrical survey), and ending in Khorasan, the great Elburz range presents on its southern, or inward, face a more or less abrupt scarp rising above immense gravel slopes, and reaches in some of its summits a height of nearly 13,000 ft.; and the peak of Demavend, north-west of Teheran, has a height of at least 18,000 ft.
North of Teheran, flows easterly through the Lar plateau, where it is known as the Lar River, and takes up several affluents; turns to the northeast at the foot of Demavend, leaving that mountain to the left, and flows due north past Amol to the Caspian.
Some fruits are famous and vie in excellence with any that European orchards produce; such are the peaches of Tabri2 and Meshed, the sugar melons of Kashan and Isfahan, the apRIes of Demavend, pears of Natanz, figs of KermgnshAh, &c. Ihe strawberry was brought to Persia about 1859, and is much cultivated in the gardens of Teherfln and neighborhood; the raspberry was introduced at about the same time, but is not much apprecIated.
The lowlands, rising but a few feet above the Caspian, and subject to frequent floodings, are extremely malarious, while the highlands, culminating with the magnificent Demavend (19,400 ft.), enjoy a tolerably healthy climate.
