Of the common trees of the plains of India—the nim, mango, babul, tamarind, shesham, palm, and plantain—not one is to be found growing on the hills. The lower slopes are covered with sal trees like the Bhabar. These cease to grow at elevations of 3000 feet above the sea-level, and, higher up, every rise of 1000 feet means a considerable change in the flora. Above the sal belt come several species of tropical evergreen trees, among the stems and branches of which great creepers entangle themselves in fantastic figures. At elevations of 4000 feet the long-leaved pine (Pinus longifolia) appears.
From 5000 to 10,000 feet, several species of evergreen oaks abound. Above 6000 feet are to be seen the rhododendron, the deodar and other hill cypresses, and the beautiful horse-chestnut. On the lower slopes the undergrowth is composed largely of begonias and berberry. Higher up maidenhair and other ferns abound, and the trunks of the oaks and rhododendrons are festooned with hanging moss.
Between elevations of 10,000 and 12,000 feet the silver fir is the commonest tree. Above 12,000 feet the firs become stunted and dwarfed, on account of the low temperatures that prevail, and juniper and birch are the characteristic trees.
There are spots in the Himalayas, at heights varying from 10,000 to 12,000 feet, where wild raspberries grow, and the yellow colt’s-foot, the dandelion, the blue gentian, the Michaelmas daisy, the purple columbine, the centauria, the anemone, and the edelweiss occur in profusion. Orchids grow in large numbers in most parts of the Himalayas.
Every hillside is not covered with foliage. Many are rugged and bare. Some of these are too precipitous to sustain vegetation, others are masses of quartz and granite. On the hillsides most exposed to the wind, only grass and small shrubs are able to obtain a foothold.
“On the vast ridges of elevated mountain masses,” writes Weber in The Forests of Upper India, “which constitute the Himalayas are found different regions of distinct character. The loftiest peaks of the snowy range abutting on the great plateaux of Central Asia and Tibet run like a great belt across the globe, falling towards the south-west to the plains of India. Between the summit and the plains, a distance of 60 to 70 miles, there are higher, middle, and lower ranges, so cut up by deep and winding valleys and river-courses, that no labyrinth could be found more confusing or difficult to unravel. There is nowhere any tableland, as at the Cape or in Colorado, with horizontal strata of rock cut down by water into valleys or cañons.
The strata seem, on the contrary, to have been shoved up and crumpled in all directions by some powerful shrinkage of the earth’s crust, due perhaps to cooling; and the result is such a jumble of contorted rock masses, that it looks as if some great castle had been blown up by dynamite and its walls hurled in all directions. The great central masses, however, consist generally of crystalline granite, gneiss, and quartz rock, protruding from the bowels of the earth and shoving up the stratified envelope of rocks nearly 6 miles above sea-level.
The higher you get up. the rougher and more difficult becomes the climbing; the valleys are deeper and more cut into ravines, the rocks more fantastically and rudely torn asunder, and the very vitals of the earth exposed; while the heights above tower to the skies. The torrents rushing from under the glaciers which flow from the snow-clad summits roar and foam, eating their way ever into the misty gorges.”
Those who have not visited the Himalayas may perhaps best obtain an idea of the nature of the country from a brief description of that traversed by a path leading from the plain to the snowy range. Let us take the path from Kathgodam, the terminus of the Rohilkhand and Kumaun railway, to the Pindari glacier.
For the first two miles the journey is along the cart-road to Naini Tal, on the right bank of the Gola river.
