campaign he had added more to our map information than all the geographers of the "old" Afghan war put together. Some of his exploits were remarkable, as for instance when he explored the Adrak Badrak pass leading from the Lughman valley to Jugdalak with no military escort whatever, trusting only to the tender mercies of an "aboriginal" guard. He thus made himself acquainted with every detail of the direct road from Kabul, _viâ_ the Kabul river, to Jalalabad; and with him our practical acquaintance with that important route has passed away. No sooner had he left Afghanistan than he was attached to the frontier party then working in the Kohat district; there he was Major Holdich's right-hand man. If there was a specially hard frontier nut to be cracked, McNair's powers of assimilating himself to Pathan manners, and of winning the confidence of all classes of natives, which had already carried him through many a perilous undertaking, were most fully utilised for the purpose of cracking it. From Kohat to Dera Ismail he was incessantly engaged in quiet little unobtrusive excursions (with full political sanction _bien entendu_) which resulted in a very complete map of the border, a map which it will be hard to supersede. There is one particularly awkward corner of our frontier--awkward from a military as well as geographical point of view--which thrusts itself forward over the general line into British territory, and which can never fail to attract the attention of the frontier traveller. This is the rocky fastness of Kafir Koh. From red salt hills south of Bahadur Khel the three-headed peak of Kafir Koh is seen standing up like a monument in the southern distance: nor is it less a conspicuous feature when viewed to the north from the Bannu road. At the back of it, to the west, is the direct road connecting the upper Meranzai valley with the Bannu district, of which the existence was known, but not the nature, when McNair took it in hand. Up the sheer face of that square-cut peak, composed chiefly of shifting sand and pebbles, which overtops the rest, McNair did his best to climb. He did not succeed for the reason that no living thing without wings has probably ever succeeded in surmounting it, although there is a legend to the effect that a specially active Waziri robber did once contrive to reach the top--and there remained to starve; but the English explorer at least got far up enough to obtain the clear view he required, and he came back richer in wisdom to the extent of many square miles of most remarkable mapping. His name soon became well known on the border, especially amongst the Waziris, and so much did they appreciate his own appreciation of themselves, that there is a story current that one well-known Mahsud chieftain stopped a Punjab Cavalry detachment near the border line and demanded a passport order from McNair. Perhaps his best achievement about this part of his career
