The work planned for the expedition is as 
follows: 
I. In topography: 
1, To make a topographical map on a scale 
of 2 miles to the inch, with a contour 
interval of 100 feet, of the Cuzco basin. 
2. To connect that part of the Vileabamba 
survey made by the topographer of the 
1911 expedition with his trans-Andean 
eross section from Abancay to Camana. 
. To make a map of the so-called Vilea- 
bamba country which lies north of Cuzco 
between and including the valleys of the 
Apurimaec and Urubamba rivers. Some 
portions of this were finished by Mr. Kai 
Hendriksen, topographer of the 1911 ex- 
pedition, but owing to the difficulties of 
the route he was only able to make a 
beginning. 
Every effort will be made to complete 
the map of Vileabamba, placing on it not 
only the ancient and modern sites, but 
also the data for further physiographical 
and geological study. 
4. To map the routes connecting the later 
Inca capital of Vitcos with the rest of 
Peru. ; 
5. To discover and identify the places men- 
tioned in the Spanish chronicles and in 
the early accounts of Peru, particularly 
the places connected with the 35 years of 
Inca rule after the advent of Pizarro. 
As many of these place names have 
changed, it will be necessary to identify 
the places by a careful comparison of 
their situation and surroundings with the 
itineraries and descriptions given in the 
chronicles. 
II. In geology: 
1. To make a careful survey of the Cuzco 
basin and its vicinity, with special refer- 
ence to the age of gravel deposits where 
human and other remains were found on 
the expedition of 1911. 
2. To make a geological reconnaissance of 
the Vilecabamba country, continuing the 
work already begun. 
III. In meteorology: 
1. To establish and equip meteorological

stations at Cuzco and at Santa Ana, sta- 
tions at which continuous observations 
may be made for several years, these ob- 
servations to be supplemented by field 
observations taken by various members of 
the expedition wherever practicable. 
IV. In pathology: 
1. To study the various diseases throughout 
the region visited, and their geographical 
extent. 
2. To study the effect of coca chewing. 
V. In osteology: 
1. To study the bone deposits in the Aya- 
huayeco quebrada where human and other 
bones were found on the 1911 expedition. 
2. To collect osteological material not only 
in the Cuzco gravels, but also in the 
mountains of Vilcabamba. 
VI. In forestry: 
To make a reconnaissance survey of the 
Vilecabamba region between the Apurimace 
and the Urubamba valleys. 
VII. In anthropology: 
1. To take photographs and physical meas- 
urements of native types throughout the 
region visited, with particular reference 
to a study of the distribution of the more 
important groups. 
2. To collect material for a study of the dis- 
tribution of types of cranial deformation. 
VIII. In archeology: 
1. To make a thorough investigation of the 
region round about and north from Cuzco 
and Pisac, photographing, measuring and 
describing whatever architectural ma- 
terial presents itself. 
2. To continue the investigation of the 
ruins discovered on the expedition of 
1911. 
3. To penetrate still further into the jungles 
of the Pampaconas Valley and beyond, to 
see whether any more remains of Inca 
occupation can be found. 
The expedition will include a geologist, an 
osteologist, a surgeon, three topographers and 
three assistants, besides the director. The 
geologist will be Professor Herbert Gregory, 
Silliman professor of geology in Yale Univer- 
sity, and the osteologist, Dr. George F. Eaton,
