flow THE Ha River Got NAMEi, 
joined stream they nm E. by X. and the Maopityans and Pianoghottos 
call it now Caphu or Kalfu. The junction of both streams is in 1° 2¥ 
lat*]Sr. and 56° 48' 43" long. W. while the barometric records gave a 
height of 540 feet above the sea. According to the reports my brother 
received, later, it seems to admit of no doul)t that the Kaphu is the 
Trombetas, Oriximina, or Curuniz of d'AcuSa, which in 1° 57' lat. S. 
falls into the Amazon in the neighbonrliood of Al»ydos. According to 
Martins, the junction is 451 Paris feet above sea-level, Avhich at all 
events, in my brother's opinion, is given too high : this Avas also the 
case with the Barra do Rio Negro which Martins fixed at 522 feet, al- 
though Fort Sao Joaquim which lies almost ^300 miles from there up 
the Rio Branco with its many cataracts, does not even reach this height. 
As I have previously remarked, the banks of the upper Trombetas, owing 
to recent discoveries, were assigned as the home for the Anmzons, after 
they had been driven out of all the districts previously ascribed to them : 
nevertheless my brother en'quired for them here also in vain, because 
even any tradition of their existence was foreign to the inhabitants of 
this area. 
942. The Wanamu, up which they now travelled, had muddy yellow 
water like the Caphiwuin : the Indians called it Yau-uh in its upper 
course. Its current amounted to about li knots an hour, in connection 
with which its bed was broken through by huge granite rocks. The 
mountains at the foot of which the i-iver turned, reached a height of 300 
feet only at particular spots : and yet the heat increased every midday all 
the more, although of a morning it seldom stood higher than 6S°. The 
Curiau which came from the 'N.W. and was some, 200 feet broad joined 
thie Wanamu in 1° 16" lat. N. Five miles farther up, my brother again 
found the first Indian hieroglyphs, since he left the Essequil)0. He had 
sought for them in vain at the junction of the Caphiwuin : if a later 
traveller should discover them there they were now hidden by the high 
rise of water. 
943. On the 3rd August in 1° 30' N. the expedition reached the 
mouth of a river, the size of the Curiau, and as the somewhat stupid 
guide answered my ^brother's en'quiry as to its name with an equally 
stupid *'HaI" he marked it under this name in his m.ap. A few miles 
farther up they stood once more at the commencement of a complete 
series of wildly-roaring cataracts. Small hills of granite boulders 
heaped one over the other, on both sides of the rebellious waters, were 
covered with a wanton wealth of vegetation and constituted the sources 
of origin of the water-falls. The woodskins had to be emptied at 
several of these, and at the last one yet another of these craft was lost, 
which proved all the more grievous as it contained their last basket with 
cassava-flour. The largest of the falls was in 1° 33' 30" N. and 88 miles 
easterly from the settlement of the ^laopityans. On the 5th August they 
again had to deploi e the loss of a woodskin. 
944. Eighteen days had now passed since they left the Maopityans. 
Hunger had already been their companion for some time, and the longed 
for Pianoghotto settlements Avould not shew themselves, when to-day, 
just as my brother's woodskin was turning a l)end of the river, they saw
