It is, then, a very fair presumption at the outset that if all these various authorities had satisfied themselves that action in Tibet was necessary, there probably was some reasonable ground for interference. What was it that influenced these sedate authorities, alike in India and in England, to depart from the natural course of leaving the Tibetans alone, to behave or misbehave themselves as they liked? What was it that persuaded these gentlemen that action, and not inaction, intervention, and not _laissez-faire_, were required, and that we could no longer leave this remote State on the far side of the mighty Himalayas severely alone? There must have been some strong reason, for it was not merely a matter of permitting an adventurous explorer to try and reach the “forbidden city.” After thirty years of correspondence what was eventually sanctioned was the despatch of a mission with an escort strong enough to break down all opposition. What was the reason? The answer to this I will eventually give. But to make that answer clear we must view the matter from a long perspective, and trace its gradual evolution from the original beginnings. And, at the start, I shall have to emphasize the point that there has always been intercourse of some kind between Tibet and India, for Tibet is not an island in mid-ocean. It is in the heart of a continent surrounded by other countries. That it is a mysterious, secluded country in the remote hinterland of the Himalayas most people are vaguely aware. But that it is contiguous for nearly a thousand miles with the British Empire, from Kashmir to Burma, few have properly realized. Still less have they appreciated that this contact between the countries means intercourse of some kind between the peoples inhabiting them, even though it has to be over a snowy range. The Tibetans drew their religion from India. From time immemorial they have been accustomed to visit the sacred shrines of India. Tibetan traders have come down to Bengal, Kashmiri and Indian traders have gone to Tibet. Tibetan shepherds have brought their flocks to the pastures on the Indian side of the range in some parts. In other parts the shepherds from the Indian side have taken their sheep and goats to the plateaux of Tibet. Sometimes the Tibetans or their vassals have raided to valleys and plains of India, sometimes Indian feudatories have raided into Tibet. At other times, again, the intercourse has been of a more pacific kind, and intermarriages between the bordering peoples and interchanges of presents have taken place. In a multitude of ways there has ever been intercourse between Tibet and India. Tibet has never been really isolated. And, as I shall in due course show, the Mission to Lhasa of 1904, was merely the culmination of a long series of efforts to regularize and humanize that intercourse, and put the relationship which must necessarily subsist between India and Tibet upon a business-like and permanently satisfactory footing.
