dome nuts, &c. Gazelles were exceedingly numerous, but shy, and
so difficult to approach that they required most careful
stalking. At this season of intense heat they drank twice a
day--at about an hour after sunrise, and half an hour before
sunset.

The great comfort of travelling along the bank of the river in a
desert country is the perfect freedom, as a continual supply of
water enables the explorer to rest at his leisure in any
attractive spot where game is plentiful, or where the natural
features of the country invite investigation. We accordingly
halted, after some days' journey, at a spot named Collodabad,
where an angle of the river had left a deep pool of about a mile
in length: this was the largest sheet of water that we had seen
throughout the course of the Atbara. A number of Arabs had
congregated at this spot with their flocks and herds; the total
absence of verdure had reduced the animals to extreme leanness,
as the goats gathered their scanty sustenance from the seed-pods
of the mimosas, which were shaken down to the expectant flocks by
the Arab boys, with long hooked poles. These seeds were extremely
oily, and resembled linseed, but the rank flavour was
disagreeable and acrid.

This spot was seven days' march from the Nile junction, or about
160 miles. The journey had been extremely monotonous, as there
had been no change in the scenery; it was the interminable
desert, with the solitary streak of vegetation in the belt of
mimosas and dome palms, about a mile and a half in width, that
marked the course of the river. I had daily shot gazelles, geese,
pigeons, desert grouse, &c. but no larger game. I was informed
