To-day the boundary-line between Bhutan and India lies generally along the summits of the last mountain-chain above the plains. Dense jungle clothes the sides of the hills and descends to meet the upward waves of the Terai Forest, which stretches along the foot of the Himalayas through Assam, Bengal, and Nepal. The mountains are cloven by deep and gloomy ravines through which swift-flowing rivers like the Menass, Raidak, Torsa, and Tista pour their waters to swell the Brahmaputra and the Ganges. Some of these torrents disappear underground a few hundred yards from the hills and leave a broad river-bed empty for miles, except during the Rains. But farther away they suddenly appear again above the surface and flow to the south. The character of the jungle in the region where they reappear is damper and more tropical than near the mountains, and has earned for the forest the title of Terai, which means "wet." Streams which on the level of Santrabari reached the plains, there vanish, to come again above the ground near Rajabhatkawa. [Illustration: CHUNABATTI.] The long belt of the Terai Jungle is nowadays patched with clearings for tea gardens; for the Duars' tea is famous. Mixed with tea grown near Darjeeling at an elevation of six thousand or seven thousand feet it forms a favourite blend. But the sportsman, no matter how fond he may be of the "cup that cheers," cannot view without regret the clearing away of thousands of acres of forests that shelter big game. And an artist would not consider the destruction of the giant, orchid-clad trees with the festoons of swinging creepers compensated for by the stretches of more profitable low green tea-bushes in symmetrical and orderly rows. Nor do the other signs of man's handiwork on a tea garden compensate for the natural beauties they replace. Hideous factories, gaunt drying and engine-houses with stove-pipe like chimneys rising above corrugated iron roofs, villages of dilapidated thatched huts sheltering the hundreds of coolies employed on the estate, and the unbeautiful bungalows of the Europeans in charge. For on each garden there are from one to four Britishers. The larger ones have a manager, two assistants, and an engineer; on the smaller ones the manager perhaps combines the functions of the others in his own person.
