aspired to invade India after accomplishing the feat of carrying an army through it. West of Kafirstan across the Hindoo Kush are, as we have said, passes innumerable, but only three which need be regarded as practicable for an advancing force, all the others more or less converging into these three. These are the Khak, the Kaoshan (or Parwan, also called Sar Alang), and the Irak. The Khak leads from Kunduz _via_ Ghori and the valley of the Indarab to the head of the Panjshir valley. Its elevation is about thirteen thousand feet. It is described as an easy pass, probably practicable for wheeled artillery. The Panjshiris are Tajaks, and, like the Kohistanis generally, are most bigoted Suniu Mohammedans. The rich and highly cultivated valley which they inhabit forms a grand highway into Kohistan and Koh Dahman; but all this land of terraced vineyards and orchards, watered by snow-cold streams from the picturesque gorges and mountain passes of the Hindoo Kush and Paghman mountains,--this very garden of Afghanistan, stretching away southwards to the gates of Kabul, is peopled by the same fierce and turbulent race who have ever given the best fighting men to the armies of the Amirs, and who have rendered the position of Kabul as the ruling capital of Afghanistan a matter of necessity; with their instincts of religious hostility, it will probably be found that the Kohistani, rather than the Hindoo Kush, is the real barrier between the north and the south. The Sar Alang or Parwan Pass leads directly from Kunduz and Ghori to Charikar and Kabul. It is the direct military route between Afghan Turkestan and the seat of the Afghan Government, but is not much used for trade. It cannot be much over eleven thousand feet elevation, and it is known to be an easy pass, though somewhat destitute of fuel and forage. The next route of importance is that which leads from Balkh, _via_ Bamian, to the Irak Pass on the Hindoo Kush, and into the upper watercourse of the Helmund River, and thence by the Unai over the Paghman range to Kabul. This is the great trade route from the markets of Turkestan and Central Asia generally to Kabul and India. The Irak, like the Parwan, is not nearly so high as has been generally assumed, while the Unai is a notoriously easy pass. This route is at present very much better known to the Russians, who have lately frequently traversed it, than to ourselves. Like the Parwan and the Khak, it is liable to be closed for three or four months of the year by snow. During the winter of 1879-80 they were open till late in December, and appear to be again free from snow about the middle of April. Between these main passes innumerable tracks follow the "durras," or lines of watercourse, over the ridges of the Hindoo Kush and Paghman, which afford easy passage to men on
