By means of a small steamer, purchasing the ivory of the Lake and River above the cataracts, which together have a shore-line of at least 600 miles, the slave-trade in this quarter would be rendered unprofitable,--for it is only by the ivory being carried by the slaves, that the latter do not eat up all the profits of a trip.

An influence would be exerted over an enormous area of country, for the Mazitu about the north end of the Lake will not allow slave-traders to pass round that way through their country.

They would be most efficient allies to the English, and might themselves be benefited by more intercourse.

As things are now, the native traders in ivory and malachite have to submit to heavy exactions; and if we could give them the same prices which they at present get after carrying their merchandise 300 miles beyond this to the Coast, it might induce them to return without going further.

It is only by cutting off the supplies in the interior, that we can crush the slave-trade on the Coast.
