They had no idea of the value of time and carriage, and it was somewhat difficult for me to convince them that the reason of the difference of prices lay entirely in what they themselves had done in coming here, and that, if the Portuguese should carry goods to their country, they would by no means be so liberal in their prices.

They imagined that, if the Cassange traders came to Linyanti, they would continue to vend their goods at Cassange prices.

I believe I gave them at last a clear idea of the manner in which prices were regulated by the expenses incurred; and when we went to Loanda, and saw goods delivered at a still cheaper rate, they concluded that it would be better for them to come to that city, than to turn homeward at Cassange.
It was interesting for me to observe the effects of the restrictive policy pursued by the Cape government toward the Bechuanas.

Like all other restrictions on trade, the law of preventing friendly tribes from purchasing arms and ammunition only injures the men who enforce it.

The Cape government, as already observed, in order to gratify a company of independent Boers, whose well-known predilection for the practice of slavery caused them to stipulate that a number of peaceable, honest tribes should be kept defenseless, agreed to allow free trade in arms and ammunition to the Boers, and prevent the same trade to the Bechuanas.
