Viloca (con .) 
with very short grass and minute plants lj'ing close tc 
the ground. There are many large gentle slopes which 
are almost without rock,and hence there is practically 
no cover for birds,and in such localites birds seem 
to be entirely absent,with the exception of an occasio¬ 
nal Muscisaxicola,Sicalis uropygialis or Geositta. 
The sides of the valleys are all very rocky,covered 
with masses of boulder which have fallen down from the 
cliffs above, in many cases the floor of the valleys 
are completely choked with massed of large fragments 
of broken rock,from the cliffs and peaks above. 
Among thes rocks there will be considerable tall clumps 
of puna grass and a little Tola,but the latter has 
practically been exterminated for a long distance 
from the camp by the Indians who use it for fuel. 
High up the sides of the valleys on the steep 
slopes will often be found considerable puna grass and 
another low bush,and here will be found Asthenes and 
Diuca and Phrygilus unicolor. Idiopsar and Muscisaxico* 
la are usually amongs the scattered rocks,while 
Chalcostigroa olivacea is found high up(l5,000 to 
16,000 feet amongst huge scattered boulders as a rule, 
perching on top of huge fragments of rock. 
Jt is a heartbreaking region to work in and good 
heart,lungs and legs are absolutely essential. 
The scenery is magnificent,but birds scarce and must 
be sought over very large areas at mxxk the cost of 
much labor.
