The effect of travel on a man whose heart is in the right place is that the mind is made more self-reliant: it becomes more confident of its own resources--there is greater presence of mind. The body is soon well-knit; the muscles of the limbs grow as hard as a board, and seem to have no fat; the countenance is bronzed, and there is no dyspepsia. 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. No one can truly appreciate the charm of repose unless he has undergone severe exertion. _27th March, 1866._--The point of land which on the north side of the entrance to the harbour narrows it to about 300 yards is alone called Pemba; the other parts have different names. Looking northwards from the point, the first hundred yards has ninety square houses of wattled daub; a ruin (a mosque) has been built of lime and coral. The whole point is coral, and the soil is red, and covered over with dense tropical vegetation, in which the baobab is conspicuous. Dhows at present come in with ease by the easterly wind which blows in the evening, and leave next morning, the land wind taking them out. While the camels and other animals are getting over their fatigues and bad bruises, we are making camels' saddles, and repairing those of the mules and buffaloes. Oysters abound on all the rocks and on the trees over which the tide flows: they are small, but much relished by the people. The Arabs here are a wretched lot physically--thin, washed-out creatures--many with bleared eyes.
