Among his diplomatic instructions Kirilof was told to avail himself of the animosity which existed between the Kirghiz and Bashkirs, to restrain it as much as possible so long as they continued subservient to the designs of Russia; but, in case of disaffection being exhibited on either side, he was to excite their mutual jealousies and thus save the expenditure of Russian troops. The exportation of ammunition was strictly prohibited, nor was Aboulkhair to be supplied with pecuniary assistance to carry on war with the Khivans, or to be encouraged in it. It was considered peculiarly desirable that as much information as possible should be acquired relative to the more distant frontier tribes, and more particularly the Zungars, who possessed Turkistan, and who ranked amongst the most powerful of these. Kirilof, however, had scarcely commenced to carry out these instructions, and had just founded the town of Orenburgh, which has since risen to a position of such importance as the emporium of the Eastern trade of Russia, when he died. Thus had it been reserved for the Empress Ann to take the first step towards accomplishing what Peter the Great had meditated, and was about to attempt after the Swedish war when death terminated his career. It was not long after Kirilof’s death before a revolt among the Bashkirs and Calmucks rendered it necessary for his successor to stimulate Aboulkhair to attack the rebellious tribes. Indeed the subjects of the Khan, unaccustomed to so much tranquillity, desired nothing better than to be let loose upon their old foes, and entered upon the war with such good will that they not only speedily succeeded in suppressing the rebellion, but created some anxiety to Russia lest a portion of her subjects might be altogether extirpated, and the counter-irritation, which she desired to preserve to keep Aboulkhair in check, destroyed; for it was evidently essential to the success of the system that no one tribe should acquire such a preponderance over the others as no longer to dread them, or require the protection of Russia. The ambition of Aboulkhair, however, was sufficiently restrained by the fear of endangering the life of his son, who was retained at St Petersburg as a hostage. Indeed, without these pledges of the good faith of the border tribes, there was no means of insuring their submission longer than it was consistent with their own convenience; and throughout the later history of the Kirghiz, we find them continually intriguing for assistance with their powerful neighbours, sending hostages to Peking as often as to St Petersburg, and endeavouring so to bring to bear the influence of their protectors as to secure their own ends, without permanently compromising their independence. Thus the allegiance of the Kirghiz to Russia was in a great degree nominal, and was resumed and cast off at pleasure. The advantages, however, which Russia derived from
