us inflammation is
frequent in the legs, and makes some of my most hardy men useless. We
have been compelled to slowness very much against my will. I too was
ill, and became better only by marching on foot. Riding exposes one to
the bad influence of the sun, while by walking the perspiration modifies
beneficially the excessive heat. It is like the difference in effect of
cold if one is in activity or sitting, and falling asleep on a
stage-coach. I know ten hot fountains north of the Orange River; the
further north the more hot and numerous they become.

[Just here we find a note, which does not bear reference to anything
that occurred at this time. Men, in the midst of their hard earnest
toil, perceive great truths with a sharpness of outline and a depth of
conviction which is denied to the mere idle theorist: he says:--]

The spirit of Missions is the spirit of our Master: the very genius of
His religion. A diffusive philanthropy is Christianity itself. It
requires perpetual propagation to attest its genuineness.

_9th November, 1872._--We got very little food, and kill a calf to fill
our mouths a little. A path east seems to lead out from these mountains
of Tanganyika. We went on east this morning in highland open forest,
then descended by a long slope to a valley in which there is water. Many
Milenga gardens, but the people keep out of sight. The highlands are of
a purple colour from the new leaves coming out. The donkey began to eat
to my great joy. Men sent off to search for a village return
empty-handed, and we must halt. I am ill and losing much blood.

_10th November, 1872._--Out from the Lake mountains, and along high
ridges of sandstone and dolomite. Our guide volunteered to take the men
on to a place where food can be bought--a very acceptable offer. The
donkey is recovering; it was distinctly the effects of tsetse, for the
eyes and all the mouth and nostrils swelled. Another died at Kwihara
with every symptom of tsetse poison fully developed.

[The above remarks on the susceptibility of the donkey to the bite of
the tsetse fly are exceedingly important. Hitherto Dr. Livingstone had
always maintained, as the result of his own observations, that this
animal, at all events, could be taken through districts in which horses,
mules, dogs, and oxen would perish to a certainty. With the keen
perception and perseverance of one who was exploring Africa with a view
to open it up for Europeans, he laid great stress
