of India which we have spent much to preserve, and it does actually serve a very important purpose in the commercial economy of India. At least one army has traversed this route from the north with the prospect before it of conquering Tibet; but it was a Mongol army, and it was worsted in a most unequal contest with Nature. India (if we include Kashmir) runs to a northern apex about the point where, from the western extension of the giant Muztagh, the Hindu Kush system takes off in continuation of the great Asiatic divide. Here the Pamirs border Kashmir, and here there are also mountain ways which have aforetime let in the irrepressible Chinaman, probably as far as Hunza, but still a very long way from the Indian peninsula. Then the Hindu Kush slopes off to the south-westward and becomes the divide between Afghanistan and Kashmir for a space, till, from north of Chitral, it continues with a sweep right into Central Afghanistan and merges into the mountain chain which reaches to Herat. From this point, north of Chitral, commences the true north-west barrier of India, a barrier which includes nearly the whole width of Afghanistan beyond the formidable wall of the trans-Indus mountains. It is here that the gates of India are to be found, and it is with this outermost region of India, and what lies beyond it, that this book is chiefly concerned. As the history of India under British occupation grew and expanded and the painting red process gradually developed, whilst men were ever reaching north-westward with their eyes set on these frontier hills, the countries which lay beyond came to be regarded as the "ultima thule" of Indian exploration, and Afghanistan and Baluchistan were reckoned in English as the hinterland of India, only to be reached by the efforts of English adventurers from the plains of the peninsula. And that is the way in which those countries are still regarded. It is Afghanistan in its relations to India, political, commercial, or strategic, as the case may be, that fills the minds of our soldiers and statesmen of to-day; and the way to Afghanistan is still by the way of ships--across the ocean first, and then by climbing upward from the plains of India to the continental plateau land of Asia. It was not so twenty-five centuries ago. One can imagine the laughter that would echo through the courts and palaces of Nineveh at the idea of reaching Afghanistan by a sea route! Think of Tiglath Pilesur, the founder of the Second Assyrian Empire, seated, curled, and anointed, surrounded by his Court and flanked by the sculptured art of his period (already losing some of the freshness and vigour of First Empire design) in the pillared halls of Nineveh, and counting the value of his Eastern satrapies in Sagartia, Ariana, and Arachosia, with outlying provinces in Northern India, whilst meditating yet further conquests to add to his almost illimitable Empire! No shadow of Babylon had stretched northward then. No premonition of a yet
