chapter 6 documents

while reading the documents I found the Christian topography very confusing  . I found how they baring for gold oddly weird and confusing they said if the  owner likes the meat he takes  the gold  but if he was unsatisfied he left the gold ? who is he leaving the gold for the owner of the meat or the native ?  the travelers can spend up to five days more of less in one country to barging and they have to come armed because the tribes might see them passing as a threat ... that is kind of scary . the  travel for 6 months in that 6 months are they barging the whole time ?
