Fortunately the sky was clear; there was abundance of fuel,
and pots were shortly boiling an excellent stew of ariel venison
and burnt onions. The latter delicious bulbs are the blessing of
Upper Egypt: I have lived for days upon nothing but raw onions
and sun-dried rusks. Nothing is so good a substitute for meat as
an onion; but if raw, it should be cut into thin slices, and
allowed to soak for half an hour in water, which should be poured
off: the onion thus loses its pungency, and becomes mild and
agreeable; with the accompaniment of a little oil and vinegar it
forms an excellent salad.
The following day's march led us through the same dead level of
grassy plains and mimosas, enlivened with numerous herds of
ariels and large black-striped gazelles (Dorcas), one of which I
succeeded in shooting for my people. After nine hours' journey we
arrived at the, valley of the Atbara, in all sixteen hours'
actual marching from Cassala.
There was an extraordinary change in the appearance of the river
between Gozerajup and this spot. There was no longer the vast
sandy desert with the river flowing through its sterile course on
a level with the surface of the country, but after traversing an
apparently perfect flat of forty-five miles of rich alluvial
soil, we had suddenly arrived upon the edge of a deep valley,
between five and six miles wide, at the bottom of which, about
200 feet below the general level of the country, flowed the river
Atbara. On the opposite side of the valley, the same vast table
lands continued to the western horizon.
We commenced the descent towards the river; the valley was a
succession of gullies and ravines, of landslips and watercourses;
the entire hollow, of miles in width, had evidently been the work
of the river. How many ages had the rains and the stream been at
work to scoop out from the flat table land this deep and broad
valley? Here was the giant labourer that had shovelled the rich
loam upon the delta of Lower Egypt! Upon these vast flats of
fertile soil there can be no drainage except through soakage. The
deep valley is therefore the receptacle not only for the water
that oozes from its sides, but subterranean channels, bursting as
land-springs from all parts of the walls of the valley, wash down
the more soluble portions of earth, and continually waste away
the soil. Landslips occur daily during the rainy season; streams
of rich mud pour down the valley's slopes, and as the river flows
beneath in a swollen torrent, the friable banks topple down into
the stream and dissolve. The Atbara becomes the thickness of
pea-soup, as its muddy waters steadily perform the duty they have
fulfilled from age to age.
