bushes that fringe the Atbara river.

The heat was intense. As we travelled along the margin of the
Atbara, and felt with the suffering animals the exhaustion of the

Nile overcame its enemies, while the Atbara shrank to a skeleton,
bare and exhausted, reduced to a few pools that lay like blotches
along the broad surface of glowing sand.

Notwithstanding the overpowering sun, there were certain
advantages to the traveller at this season; it was unnecessary to
carry a large supply of water, as it could be obtained at
