An  examination  of  the  map  and  of  Bollaert 's  re-
port which  accompanies  the  map,  reveals  that  the
authors  thereof  did  not  visit  the  region  of  Camarones
except  that  part  of  it  that  is  next  to  the  sea.  Thus
while  all  the  points  on  the  road  between  Pisagua  and
Isluga  appear  in  detail,  the  region  that  stretches  to
the  north,  is  left  to  the  fancy.  The  ravine  of  Cama-
rones, also  called  Taraguire  and  Cara  on  this  map,  re-
ceives two  tributaries  from  the  southeast:  the  Tanca
and  the  Guayhuasa  (Guayguase)  which  appear  as  ris-
ing on  either  side  of  the  Chulluncani  hill  which  is
drawn  almost  thirty  kilometres  to  the  south  of  its
true  position.  Then,  it  is  evident  that  the  Tanca
Eiver  (the  stream  Veco  on  our  map)  and  the  Guay-
guase are  indirect  and  secondary  tributaries  of  the
Camarones  River.
The  northern  boundary  of  Tarapaca,  according  to
Bollaert 's  map,  commences  on  the  seacoast  at  18°  57',
far  to  the  north  of  the  mouth  of  the  Camarones,  goes
on  almost  parallel  until  it  falls  into  the  ravine  of
Taltapia  (Taltape),  and  from  there  it  continues  as
far  as  Chulluncani  hill.  Because  of  the  erroneous
position  of  this  hill,  the  boundary  line  traced,  falls
to  the  south  of  the  Guayguase  River,  but  it  is  quite

evident  that  no  positive  deductions  can  be  made  from
a  map  as  erroneous  as  this  one  is,  at  this  point.
