LEECHES IN STOMACH OF LETZWEE 149 
that we were something like two thousand miles from the coast, 
with no appliances for collecting, and only vague possibilities 
of ever being able to transport such frail goods safely to the 
coast. Collecting requires time and opportunity. This must 
be left to those that come after us to fulfil. 
While waiting for Jeluka’s pleasure to visit us, Hammar 
crossed the Loengwe in a canoe, to have a shot at some letzwee 
buck visible opposite, and returned with two that fell to his 
gun. We found that besides the ordinary worm inhabiting the 
letzwee there were also many leeches which clung tenaciously to 
the mucous membrane of the stomach after the buck’s death. 
Hammar also reported that what appeared to be mainland on 
the other side was only an island dividing the Loengwe into two 
branches, which flow into the Chobe under the ever-prevailing 
masses of floating reeds.
