638 KANSAS CITY REVIEW OF SCIENCE. 



hibits, all of which will be displayed in the National Museum after the close of 

 the exposition. 



Among other objects of interest and wonder will be the series of models of 

 the towns of the existing Pueblo tribes, and of the ruins, cliff-dwellings, and 

 towns of the pre-historic peoples. An entirely new series of these has been made 

 on a scale of one-sixtieth — large enough to show much of the interesting details 

 of their architecture and habits of life. The model of the Pueblo of Zuni, the 

 largest, is upward of twenty feet long. Appended to this display will be a num- 

 ber of models of the mounds, earthworks, etc., of the mound-builders. A series 

 of the relics of stone, clay, metal, various tools and implements, and a represen- 

 tation of the skeletons obtained from the mounds. This branch of the work is 

 under the special supervision of Prof. Cyrus Thomas, who has been engaged 

 during the past four or five years investigating the origin and possible history of 

 these unknown people. 



The Geological Survey will furnish a number of models of the more im- 

 portant geologic and typographic features of the far west, — the Grand Cafion 

 of the Colorado, the Yellowstone Park, the Yosemite Valley, and the grand dis- 

 trict of the Rocky Mountains. There will also be a number of models of the 

 great mines of Colorado, Nevada, and California. 



A fine collection of the largest and most elegant photographs ever made will 

 be shown by the transparencies, and will be an exceedingly attractive feature of 

 the exposition. There will be 150 of these pictures which will illustrate chiefly 

 the people and scenery of the far west. They will be returned to the National 

 Museum after the close of the exposition. 



There will also be sent from the United States Geological Survey specimens 

 representing the ancient life of the globe, the fishes and reptiles of strange form, 

 some of them of immense size, the multitude of remarkable quadrupeds which 

 have become extinct, the infinitely varied forms of shell fish which have inhabited 

 the seas of former geological periods, and remains of the mighty forest trees that 

 once covered a large portion of the earth's surface, and which have been suc- 

 ceeded by those which now decorate the earth. This exhibit will include min- 

 erals of nearly every kind known to science, from the beautiful and costly gem 

 to the common clay of the potter; ores of every metal known to human industry, 

 representations of the mines whose wealth is fabulous, maps and charts showing 

 the location of all this natural wealth, the extent and methods of its development, 

 and giving plain indications of their future productiveness. 



The space required for the exhibits of the interior department is as follows : 

 For the Patent Office, 15,650 square feet floor and 1,800 feet wall space. Geo- 

 logical Survey, 10,000 square feet floor and about 1,500 wall space. Pension 

 Office, 600 feet floor and seventy-five feet wall. General Land Office, 300 feet 

 floor and 1,400 feet wall. Commissioner of Railroads, 2,000 feet wall space and 

 floor space to view exhibits. Census Office, 300 feet wall and floor space to 

 view exhibits. The total floor space required is 35,000 square feet.
