best treated by change of climate, we have the remedy at hand by passing the 20th parallel on our way south.  But I am not to be understood as intimating that any of the numerous tribes are anxious for instruction:  they are not the inquiring spirits we read of in other countries; they do not desire the Gospel, because they know nothing about either it or its benefits; but there is no impediment in the way of instruction.  Every head man would be proud of a European visitor or resident in his territory, and there is perfect security for life and property all over the interior country.  The great barriers which have kept Africa shut are the unhealthiness of the coast, and the exclusive, illiberal disposition of the border tribes.  It has not within the historic period been cut into by deep arms of the sea, and only a small fringe of its population have come into contact with the rest of mankind.  Race has much to do in the present circumstances of nations; yet it is probable that the unhealthy coast-climate has reacted on the people, and aided both in perpetuating their own degradation and preventing those more inland from having intercourse with the rest of the world.  It is to be hoped that these obstacles will be overcome by the more rapid means of locomotion possessed in the present age, if a good highway can become available from the coast into the interior.

Having found it impracticable to open up a carriage-path to the west, it became a question as to which part of the east coast we should direct our steps.  The Arabs had come from Zanzibar through a peaceful country.  They assured me that the powerful chiefs beyond the Cazembe on the N.E., viz., Moatutu, Moaroro, and Mogogo, chiefs of the tribes Batutu, Baroro, and Bagogo, would have no objection to my passing through their country.  They described the population there as located in small villages like the Balonda, and that no difficulty is experienced in traveling among them.  They mentioned also that, at a distance of ten days beyond Cazembe, their path winds round the end of Lake Tanganyenka.  But when they reach this lake, a little to the northwest of its southern extremity, they find no difficulty in obtaining canoes to carry them over.  They sleep on islands, for it is said to require three days in crossing, and may thus be forty or fifty miles broad.  Here they punt the canoes the whole way, showing that it is shallow.  There are many small streams in the path, and three large rivers.  This, then, appeared to me to be the safest; but my present object being a path admitting of water rather than land carriage, this route did not promise so much as that by way of the Zambesi or Leeambye.  The Makololo knew all the country eastward as far as the Kafue, from having lived in former times near the confluence of that river with the Zambesi, and they all advised this path in preference to that by the way of Zanzibar.  The only difficulty that they assured me of was that in the falls of Victoria.  Some recommended my
