Having missed the narrow entrance to
the canal, she had struck the dam stem on; the force of the current
immediately turned her broadside against the obstruction, the floating
islands and masses of vegetation brought down by the river were heaped
against her and, heeling over on her side, she was sucked bodily under
and carried beneath the dam. Her crew had time to save themselves by
leaping upon the firm barrier that had wrecked their ship. The boatmen
told me that dead hippopotami had been found on the other side, that had
been carried under the dam and drowned.
Two days' hard work from morning till night brought us through the
canal, and we once more found ourselves on the open Nile on the other
side of the dam. The river was in that spot perfectly clean; not a
vestige of floating vegetation could be seen upon its waters. In its
subterranean passage it had passed through a natural sieve, leaving all
foreign matter behind to add to the bulk of the already stupendous work.
All before us was clear and plain sailing. For some days two or three of
our men had been complaining of severe headache, giddiness, and violent
pains in the spine and between the shoulders. I had been anxious when at
Gondokoro concerning the vessel, as many persons while on board had died
of the plague, during the voyage from Khartoum.
