Note 329 — Chapter I · THE AFFGHANISTAN CAMPAIGNS.326

“They now entered upon the passage of the terrible Bolan Pass, a huge chasm, running between precipitous rocks to the length of seventy miles, and rising in that distance to the height of 5,637 feet above the plains below, which are here about 750 feet in height above the level of the sea. The dangerous defiles which abound in these mountains are infested by the poorest and wildest tribes of the country, who live entirely by plunder; but they fortunately refrained from molesting the troops to the extent which they might have done.”—War in Affghanistan.
