It was long the wisdom of Anglo-Indian statesmen to preserve a situation which contained so many elements of finality, and so many guarantees of peace. When the northern savages, impelled by fanaticism or allured by plunder, descended from the mountains and invaded the plains, they were met by equal courage and superior discipline, and driven in disorder to their confines. But this was found to be an inadequate deterrent, and the purely defensive principle had to be modified in favor of that system of punitive expeditions which has been derided as the policy of "Butcher and Bolt." Gradually, as the circumstances altered, the methods of dealing with them changed. The punitive expeditions had awakened an intense hostility among the tribesmen. The intrigues of Russia had for some time been watched with alarm by the Indian Government. As long as the border could remain a "No-man's land"--as it were a "great gulf fixed"--all was well; but if any power was to be supreme, that power must neither be Russia nor Afghanistan. ["We shall consider it from the first incumbent upon the Government of India to prevent, at any cost, the establishment within this outlying country of the political preponderance of any other power."--Letter from Government of India to the Secretary of State, No.49, 28th February, 1879.] The predominance of Russian influence in these territories would give them the power to invade India at their discretion, with what chances of success need not be here discussed. The predominance of Afghan influence would make the Amir master of the situation, and enable him to blackmail the Indian Government indefinitely. A change of policy, a departure from the old frontier line, presented itself with increasing force to responsible men. To-day we see the evils that have resulted from that change. The dangers that inspired it have been modified.
