party found that not only ihv Zuruniatas, but five of the Maopityans had 
di.sappeared : the remaining one seemed ready to follow suit. After 
proceeding another ten miles down the Wanamu, they turned into the 
Irian, the current of which was broken by a number of drifting trees 
and rapids. On tlie 18tb August they again came across the Maopityans 
who had followed them by land. During the 19th three of| the 
^laopityans again left tbcni clandestinely, so tliat imy lirother found

The height above sea level \vas 704 feet. It was evident from several

their way througli swamp and over liill. they hit on a camping ground 
that could hardly have been left an hour before: half an hour later they 
reached a Pianoghotto village wliere tbey were awaited and welcomed 
by the athletic and well-built inhabitants. In their costume they quite
