The rope fitted to the harpoon was beautifully made of plantain fibre,
and the float was a huge piece of ambatch-wood about fifteen inches in
diameter. They speared the hippopotamus from canoes, and these large
floats were necessary to be easily distinguished in the rough waters of
the lake.
My men were perfectly astounded at the appearance of the lake. The
journey had been so long, and "hope deferred" had so completely sickened
their hearts, that they had long since disbelieved in the existence of
the lake, and they were persuaded that I was leading them to the sea.
They now looked at the lake with amazement--two of them had already
seen the sea at Alexandria, and they unhesitatingly declared that this
was the sea, but that it was not salt.
Vacovia was a miserable place, and the soil was so impregnated with
salt, that no cultivation was possible. Salt was the natural product of
the country; and the population were employed in its manufacture, which
constituted the business of the lake shores--being exchanged for
supplies from the interior. I went to examine the pits: these were about
six feet deep, from which was dug a black sandy mud that was placed in
large earthenware jars; these were supported upon frames, and mixed with
water, which filtering rapidly through small holes in the bottom, was
received in jars beneath: this water was again used with fresh mud until
it became a strong brine, when it was boiled and evaporated.
