How the Work 10 Done.
The guano workers are practical
all Peruvlans of the ancient stock, an'
many of them come down from MI
mountains to engage In this wos [;
Often there are few In the camp VII
can speak Spanish and the fOrema
can communicate with the employee
only by signs or through an lnterpt
ter.
The extraction OF guano Is q vi
simple process. Where the matehj
Is comparatively recent, the only d
plements required are the pick an'
the shovel, screen and few sack
The surface cake Is first broken
and thrown into small heaps. Whs1
several contractors have a concessl
from the government covering
same island, there is much rivalry
getting the best guanO mounded'
this is the only recognized method
establishing a claim to Il partieul
field.
The guano is subsequently ptchi
through slantlng wire screens 70
move the gravel, and then sacked
embarkation by lanchas, which a
strongly constructed lighters In y
form of rowboats, adapted for use
the heavy swell liable TO prevail aOO
the islands.
A very common method OF COVE
ing the guano to the lighter Is BY meal
of the andarivel, an aerial trolley q
sIsting of two stout wire cables "
pended between a frame at the 'Op
