The hill-station of Darjiling, the well-known sanitarium, where the health of Europeans is recruited by a temperate climate, is about 370 miles to the north of Calcutta. The ridge "varies in height from 6,500 to 7,500 feet above the level of the sea, 8,000 feet being the elevation at which the mean temperature most nearly coincides with that of London, viz., 50°." {193} The forests around Darjiling are composed principally of magnolias, oaks, laurels, with birch, alder, maple, holly. Dr. Hooker draws especial attention to the absence of _Leguminosae_, "the most prominent botanical feature in the vegetation of the region," which, he says, is too high for the tropical tribes of the warmer elevation, too low for the Alpines, and probably too moist for those of temperate regions; cool, equable, humid climates being generally unfavorable to the above-named order. "The supremacy of this temperate region consists in the infinite number of forest trees, in the absence (in the usual proportion, at any rate) of such common orders as _Compositae, Leguminosae, Cruciferae_ and _Ranunculaceae_, and of grasses amongst Monocotyledons, and in the predominance of the rarer and more local families, as those of rhododendron, camellia, magnolia, ivy, cornel, honeysuckle, hydrangea, begonia, and epiphytic orchids." We regret that want of space prevents us dwelling longer on the scenes of tropical Himalaya, so graphically described by Dr. Hooker. We will conclude this imperfect sketch with our traveller's description of the scenery along the banks of the great Rungeet, 6,000 feet below Darjiling:
