it becomes their prey.

Mr Oswell, who had arrived too late for the journey, spent the
remainder of the season in hunting elephants, liberally presenting Dr
Livingstone with the proceeds of his sport, for the outfit of his
children.

The third journey was commenced in the spring of 1851, when, rejoined by
Mr Oswell, he set out once more, accompanied by Mrs Livingstone and
their children.

First travelling north, and then to the north-east, through a region
covered with baobab-trees, abounding with springs, and inhabited by
Bushmen, they entered an arid and difficult country. Here, the supply
of water being exhausted, great anxiety was felt for the children, who
suffered greatly from thirst. At length a small stream, the Mababe, was
reached, running into a marsh, across which they had to make their way.
During the night they traversed a region infested by the _tsetse_, a fly
not much larger than the common house-fly, the bite of which destroys
cattle and horses. It is remarkable that neither man, wild animals, nor
even calves as long as they continue to suck, suffer from the bite of
this fearful pest. While some districts are infested by it, others in
the immediate neighbourhood are free, and, as it does not bite at night,
the only way the cattle of travellers can escape is by passing quickly
through the infested district before the sun is up. Sometimes the
natives lose the whole of their cattle by its attacks, and travellers
frequently have been deprived of all means of moving with their wagons,
in consequence of the death of their animals; some, indeed, have
perished from being unable to proceed.

Having reached the Chobe, a large river, which falls into the Zambesi,
leaving their attendants encamped with their cattle on an island, Dr
Livingstone and his family, with Mr Oswell, embarked in a canoe on the
former river, and proceeded down it about twenty miles to an island,
where Sebituane was waiting to receive them.

The chief, pleased with the confidence the doctor had shown in bringing
his wife and children, promised to take them to see his country, that
they might chose a spot where they might form a missionary station. He
had been engaged in warfare nearly all his life, under varying fortunes,
with the neighbouring savage tribes, and had at length established
himself in a secure position behind the Chobe and Leeambye, whose broad
streams guarded him from the inroads of his enemies. He had now a
larger
