channel separates opposing shores, the Eastern Empire of Great Britain
from that of Russia. The western end of this tumult of ground is formed
by the peaks of the Hindu Kush, to the south of which is the scene of
the story these pages contain. The Himalayas are not a line, but a great
country of mountains. By one who stands on some lofty pass or commanding
point in Dir, Swat or Bajaur, range after range is seen as the long
surges of an Atlantic swell, and in the distance some glittering snow
peak suggests a white-crested roller, higher than the rest. The
drenching rains which fall each year have washed the soil from the sides
of the hills until they have become strangely grooved by numberless
water-courses, and the black primeval rock is everywhere exposed. The
silt and sediment have filled the valleys which lie between, and made
their surface sandy, level and broad. Again the rain has cut wide, deep
and constantly-changing channels through this soft deposit; great
gutters, which are sometimes seventy feet deep and two or three hundred
yards across. These are the nullahs. Usually the smaller ones are dry,
and the larger occupied only by streams; but in the season of the rains,
abundant water pours down all, and in a few hours the brook has become
an impassable torrent, and the river swelled into a rolling flood which
caves the banks round which it swirls, and cuts the channel deeper year
by year.

From the level plain of the valleys the hills rise abruptly. Their steep
and rugged slopes are thickly strewn with great rocks, and covered with
coarse, rank grass. Scattered pines grow on the higher ridges. In the
water-courses the chenar, the beautiful eastern variety of the plane
tree of the London squares and Paris boulevards, is occasionally found,
and when found, is, for its pleasant shade, regarded with grateful
respect. Reaching far up the sides of the hills are tiers of narrow
terraces, chiefly the work of long-forgotten peoples, which catch the
