282). As to the canoe, in order to prevent the sides from opening 
too much, the open ends are firmly tied before being subjected to 
the heat of the flames. Otherwise its manufacture is identical with 
that of a corial. 
794. The following are some of the timbers from which corials 
and canoes are manufactured : 
Nectandra spp. The brown and yellow silverbally or siruaballi 
(Arawak), the former being considered the best available, and does 
not sink. Other local terms are determa, tataroma, etc. 
Cedrela odorata Linn. Brown cedar, tenyari or mara (Arawak). 
One of the canoes employed by Schomburgk during an expedition to 
the interior was 42 feet long and 54 feet wide. It was hollowed out 
of a single trunk of this tree (CC, 31). 
Copaifera pubifiora Benth. Purpleheart. Sinks when swamped. 
Dimorphandra mora Benth. (Mora excelsa). Sinks. 
Goupia glabra Aubl. Kabukalli (Arawak). Sinks. 
Vochysia tetraphylla Aubl. Iteballi. The wood is not durable 
when exposed to the weather, but is soft’ and easily worked (CC, 36). 
Bombax ceiba and B. globosum. Silk-cotton tree. Not durable. 
Some of the largest canoes are made from this tree. Schomburgk 
speaks of them holding 70 to 80 people, as well as two 3-pounders, 
when employed in the Venezuelan revolutionary war. Used by War- 
rau on the Waini (SR, 1, 144). 
Carapa guianensis. Crab wood. It has the same objections as the 
preceding. 
Protium (Icica) guianense March. Incense tree. Easy to work, 
but only of medium quality. Apalai Indians of the Parou River 
(Cr, 304). 
Protium (Icica) altissima. Wapishana (SR, u, 362). 
I only know of the following by their native names: 
Anni. A fine tal] tree with a prickly nut, of which Indians on the 
Cuyuni make their corials (Sc, 167). 
Korohura or kurohara (Arawak). Sinks. 
Tatabo (Arawak). Sinks. 
Bist, A gigantic tree. Used for constructing corials and canoes. 
It yields a resin of a greenish color which is used by the Indians to 
give a gloss to their bows, etc. (ScD, 35). Bisee craft are mentioned 
by Hilhouse (HiB, 328). 
795. If the canoe is to be used for long journeys a tent is added for 
protection, not of the Indians themselves, but of their goods. A 
number of sticks are bent into semicircles and the two ends are fas- 
tened, one against each side of the canoe, so as to make a framework 
for the tent. These are held in place by cross sticks tied on at right 
angles, and on the framework thus made a thatch of palm leaves is
