While still at Tete the son of Monomotapa paid the commandant a visit.  He is named Mozungo, or “White Man”, has a narrow tapering head, and probably none of the ability or energy his father possessed.  He was the favorite of his father, who hoped that he would occupy his place.  A strong party, however, in the tribe placed Katalosa in the chieftainship, and the son became, as they say, a child of this man.  The Portuguese have repeatedly received offers of territory if they would only attend the interment of the departed chief with troops, fire off many rounds of cartridges over the grave, and then give eclat to the installment of the new chief.  Their presence would probably influence the election, for many would vote on the side of power, and a candidate might feel it worth while to grant a good piece of land, if thereby he could secure the chieftainship to himself.  When the Portuguese traders wish to pass into the country beyond Katalosa, they present him with about thirty-two yards of calico and some other goods, and he then gives them leave to pass in whatever direction they choose to go.  They must, however, give certain quantities of cloth to a number of inferior chiefs beside, and they are subject to the game-laws.  They have thus a body of exclusive tribes around them, preventing direct intercourse between them and the population beyond.  It is strange that, when they had the power, they did not insist on the free navigation of the Zambesi.  I can only account for this in the same way in which I accounted for a similar state of things in the west.  All the traders have been in the hands of slaves, and have wanted that moral courage which a free man, with free servants on whom he can depend, usually possesses.  If the English had been here, they would have insisted on the free navigation of this pathway as an indispensable condition of friendship.  The present system is a serious difficulty in the way of developing the resources of the country, and might prove fatal to an unarmed expedition.  If this desirable and most fertile field of enterprise is ever to be opened up, men must proceed on a different plan from that which has been followed, and I do not apprehend there would be much difficulty in commencing a new system, if those who undertook it insisted that it is not our custom to pay for a highway which has not been made by man.  The natives themselves would not deny that the river is free to those who do not trade in slaves.  If, in addition to an open, frank explanation, a small subsidy were given to the paramount chief, the willing consent of all the subordinates would soon be secured.
