The pacific vocations of the Seri are few. They are totally without
agriculture, and even devoid of agricultural sense, though they consume
certain fruits and seeds in season; they are without domestic animals,
though they live in cotoleration with half-wild dogs, and perhaps
with pelicans; and they are without commerce, save that primitive
and inimical interchange commonly classed as pillage and robbery.
Accordingly, their pacific industries are limited to those connected
with (1) sustentation, chiefly by means of fishing and the chase;
(2) navigation and carrying, (3) house-building, (4) appareling, and
(5) manufacturing their simple implements and utensils; and these
constructive industries are balanced and conditioned by the destructive
avocation of (6) nearly continuous warfare.
