David Livingstone,
The Last Journals of David Livingstone…
“ Africa is a most wonderful country for appetite, and it is only when one gloats over marrow bones or elephant's feet that indigestion is possible. No doubt much toil is involved, and fatigue of which travellers in the more temperate climes can form but a faint conception; but the sweat of one's brow is no longer a curse when one works for God: it proves a tonic to the system, and is actually a blessing. ”
