O EGYPT AND THE SOUDAN.
mounted infantry. The baggage camels were arranged in column
with from twenty to thirty marching abreast, and with fifty yards
interval between each troop. The guards in front and the mounted
infantry in rear were in close column of companies ready to dismount and form a square at a moment's notice. Lord Wolseley inspected
the whole force, and the little party of cavalry scouts, under Major
Kitchener, with six Arab guides, moved off in front. A quarter
of an hour later the general gave the order, and the great column
got in motion, striking straight across the undulating plain towards
the distant horizon, the two thousand camels with their necks
stretched out, and their long legs moving slowly in apparently
mechanical strides, until the rising dust enveloped them and all
that followed in a gray mist, and finally hid from view the whole
column, which, broad as was its face, extended for a mile in length. No natives accompanied the column, except the guides who went
with the hussar scouts, a few others with a guard of mounted
infantry in the rear, a few servants from Cairo, and the camel-
drivers.
The first regular wells at which the column would arrive were
at Hambok, about forty miles distant, and they are merely holes dug in the sand and deepened as the subterranean waters fall,
until either the sides cave in, or the whole excavation is obliterated by the rush of water down the wady during the rainy season. The water is mostly drawn from these and all similar wells in the Bayuda by means of rough skin bags, and is then poured into
small earthen cisterns made on the surface, at which camels, sheep,
and horses are watered; these wells are rarely more than twenty
to twenty-five feet deep.
Near this point, at thirty-eight miles from Ambukol, the wady,
which has hitherto been flat and sandy, with very gently sloping
sides, becomes much broken, small metamorphic ridges, hills, and
lava-like mounds close in, showing that the belt of metamorphic
rock interveninof between the lower Nubian sandstone and the
extensive granite rocks is beinor traversed. The hills assume
curious forms : some, of black basalt, are almost perfectly conical,
whilst the rock of which they are composed is so magnetic as
