476 ACROSS AFRICA. [Chap 



to a swan-sliot. I asked whence they came, and he said that 

 some of his slaves at Katanga found them while clearing ont 

 a water-hole, and brought them to him, thinking that they 

 might do for shot. He said he had not looked for more, as 

 he did not know such little bits were of any use. 



The natives, too, know of the gold ; but it is so soft they do 

 not value it, preferring " the red coj)per to the white." 



I heard, when at Benguela, that gold had been found in cop- 

 per brought from Katanga, and that a company was buying all

 university missions are pushing their way forward. 



Missionary efforts, however, will not avail to stop the slave- 

 trade, and open the country to civilization, unless supplemented 

 by commerce. Commercial enterprise and missionary effort, in- 

 stead of acting in opposition, as is too often the case, should 

 do their best to assist each other. Wherever commerce finds

The philantln-opic efforts of His Majesty the King of the 

 Belgians, if they meet with the support they deserve, although
