that the Combos practise the art of knitting cotton 
cloth, which they fashion into long cloaks. The cloth, 
of which I saw many specimens, forms a regular, durable, 
and not inelegant web of tolerably close texture. The 
Conibos, like the Indians of Peru, do not grow the 
poisonous kind of mandioca, but simply the sweet kind, 
or Macasheira (Manihot Aypi). I estimate the length 
of the Jutahi at about 400 miles, and that of the Jurua 
at 600 miles. 
We remained at anchor four days within the mouth 
of the Sapo, a small tributary of the Jutahi flowing 
from the south-east ; Senhor E-aiol having to send an 
igarite to the Cupatana, a large tributary some few miles 
further up the river, to fetch a cargo of salt fish. During 
this time we made several excursions in the montaria 
to various places in the neighbourhood. Our longest 
trip was to some Indian houses, a distance of fifteen 
or eighteen miles up the Sapo, a journey made with 
one Indian paddler, and occupying a whole day. The 
stream is not more than forty or fifty yards broad ; its 
waters are darker in colour than those of the Jutahi, 
and flow, as in all these small rivers, partly under shade 
between two lofty walls of forest. We passed, in ascend- 
ing, seven habitations, most of them hidden in the , 
luxuriant foliage of the banks ; their sites being known 
only by small openings in the compact wall of forest, 
and the presence of a canoe or two tied up in little 
shady ports. The inhabitants are chiefly Indians of 
the Maraua tribe, whose original territory comprised all 
the small by-streams lying between the Jutahi and 
the J urua, near the mouths of both these great tribu-
