are located near the houses, and their cultivation is left 
to the men. Women gather the leaves. 
As in the case of coca, tobacco has a part in the mys- 
ticism of these Indians. Tobacco-concentrate, ambira, 
which, like coca, is kept in a gourd, is prepared by a long 
steeping of the leaves and by mixing the resulting liquid 
with yuca-starch (Manihot utilissima) and sugu (Sorghum 
sp.). There is a certain similarity between the use of to- 
bacco in this form and that characteristic of the Witotos 
of the Amazonas, and, in fact, there is some analogy in 
the mythology of these two groups of Indians (50). 
Motilon: linguistic family Karid, according to Rivet 
(38). 
The Yuco, as they call themselves, who live in the 
Sierra de Perijéa, Departamento del Magdalena, belong 
to the Karib group, but the famous ‘‘Motilones’’ of the 
Catatumbo appear to be Arawaks (82). 
This tribe grows tobacco in a rather primitive manner. 
In preparing tobacco, they merely hang leaves from the 
rafters of the houses to dry. ‘The dried tobacco is care- 
fully kept in baskets by the men. Smoking is done only 
in pipes. Both sexes and all ages smoke, children pass- 
ing from their mother’s breast to pipes. The pipes are 
of clay with a wooden stem (83). 
It seems that the Yuco knew of coca and chewed it 
until very recently. It has now completely disappeared. 
Yuco coca-chewing was probably due to commercial re- 
lations with the Indians of the Sierra Nevada, for the 
Yuco did not grow coca, notwithstanding an appropriate 
climate, and, significantly, it was that fringe of the Moti- 
lones nearest Sierra Nevada which knew of the coca- 
chewing custom. 
Chimila: linguistic family Arawak, according to 
Reichel-Dolmatoff (81).
