1878. | United States Survey of the Territories. III 
Survey was instructed, in connection with its regular work, to visit 
and report upon these ruins, and in pursuance of this objeet made 
a hasty tour of the region about the Mesa Verde and the 
Sierra el Late, in South-western Colorado, the results of which 
trip, as expressed by Bancroft, in the Native Races of the Pacific 
Coast, “ although made known to the world only through a three 
or four days’ exploration by a party of three men, are of the 
greatest importance.” A report was made and published, with 
fourteen illustrations, in the Bulletin of the United States Geolog- 
ical and Geographical Survey of the Territories, second series, 
No. I. 
The following year the same region was visited by Mr. W. H. 
Holmes, one of the geologists of the survey, and a careful investi- 
gation made of all the ruins. Mr. Jackson, who had made the re-. 
port the previous year, also revisited this locality, but extended 
his explorations down the San Juan to the mouth of the De 
Chelly, and thence to the Moqui villages in North-eastern Arizona. 
Returning, the country between the Sierra Abajo and La Sal and 
the La Plata was traversed, and an immense number of very in- 
teresting ruins were first brought to the attention of the outside 
world by the report which was published the following winter by 
Messrs. Holmes and Jackson, in the Survey, Vol. II., No. 1. 
The occasion of the Centennial Exhibition at Philadelphia led 
to the idea of preparing models of these ruins for the clearer illus- 
tration of their peculiarities, four of which were completed in sea- 
son for the opening of the Exhibition. Since that time not only 
the number of these interesting models has been increased, but 
they have been perfected in. execution, and faithful delineations 
have thus been secured of these mysterious remains of an extinct 
race who once lived within the borders of our western domain. 
A visit to the aéelier of Mr. Jackson, photographer of the Sur- 
vey, enables one to inspect, in miniature size, the dwellings of the 
Mogqui, and in full size a large collection of the ceramics and im- 
plements of those ancient and extinct people of our continent. A 
study of the models will give a very excellent idéa of the ruined 
dwellings themselves. The first of these models, executed by Mr. 
Holmes, with whom the idea originated, represents the cliff house 
_ of the Mancos Cañon, the exterior dimensions of which are 28 
inches in breadth by 46 inches in height, and on a scale of 1.24, 
or two feet to the inch. This is a two-story oe constructed
