region, since it was at a time when heavy 
rams might begin at any moment (Feb. 6 to 10th .) J 
which would flood the Salar with water and make its cross 
ing impossible,in which case it would have been extremely 
difficult to get back to Uyuni, The only way would 
have been a trip of about 80 kilometers south to the 
Paily running from Uyuni to Antofagasta,Chile,and 
to secure the necessary animals for packs and saddle for 
the trip would have almost an impossibility. Very reluct 
antly.I returned to uyuni by a truck belonging to the 
municipality, which makes two or three trips a month out 
whenever the condition of the Salar permits. 
Pulacavo (13,400 feet) 
After our return from Llica,I made a trip up,to 
Pulacayo,going up in the evening and shooting the next 
day and returning the same evening to Uyuni. It is only 
30 kilometers by aito road, from Uyuni,but considerably 
further by the railway. The mine (tin) lies northeast of 
Uyuni,up in the range of low mountains which extends 
westward from the eastern cordillera as far as Uyuni. 
The mine is in a cup shaped valley rim the west side oi 
of a group of peaks rising up to about 14,500 feet. 
The whole region is very dry,no running water sx and 
very few small.springs anywhere near. The water for 
the mine,that is for the consumption of the people,is 
brough nearly 20 kilometers in a pipeline,but the 
water used in the mill of the mine is pumped from the 
mine itself. I collected there above the mine,up to 
the top of the range,and although it was so very dry, 
I found bird life fairly abundant and secured ten 
species of birds,taking the following where were not 
seen around Uyuni: Muscisaxicola albiloraiM.-fln.viniirfrm 
Phrygilus unicolor .and g. erythronotus “
