postponed from 1903 to 1904, and opportunity was thus offered for the 

 preparation of an adequate display that might ilkistrate the functions 

 of the Institution and its dependencies. 



The Smithsonian exhibit proper is installed in the Government build- 

 ino- in a pavilion which overlooks the space assigned to its various 

 bureaus. It contains memorials and a portrait of the founder, James 

 Smithson, and a complete series of the several hundred puV)lications of 

 the Institution, which represents one of the chief means adopted for 

 carrying out his purpose "The increase and diffusion of knowledge." 

 Portraits of the chancellors and secretaries of the Institution are also 

 shown, as well as that of Mr. Thomas George Hodgkins, the donor of 

 the Hodgkins fund. Printed matter, setting forth the objects to which 

 this fund is devoted and the reports of important original researches 

 which it has aided by means of grants, are also exhibited, with repro- 

 ductions of the Hodgkins gold medal, which is awarded biennially for 

 noteworthy investigations regarding the nature of atmospheric air in 

 connection with the welfare of man. One of the features of the 

 exhibit is a (|uarter-size niodel of the large aerodrome with which 

 experiments were conducted during the summer and autumn of 1903, 

 a model, driven by a gasoline engine, which itself has Hown a distance 

 of nearly a quarter of a mile. The steam-driven model with which 

 experiments were successfully made in 1896 is also exhibited. 



The work of the Astroph3\sical Observatory is illustrated in a 

 graphic manner by the installation of the great coelostat, arranged to 

 throw a beam of sunlight into a darkened room where there is shown 

 a solar image about a yard in diameter, thrown up b}' a 6-inch tele- 

 scope, and the solar spectrum is formed upon the walls by a large 

 concave grating. Bolometric apparatus is in actual operation, while 

 a display of transparencies illustrates the apparatus and results of 

 researches by the Observatory. 



Charts and other objects are displayed explanatory of the useful 

 work carried on by the International Exchanges in distril)uting scien- 

 tific publications throughout the world. 



The various departments of the National ]\Iuseuni are fully repre- 

 sented. Among some of the objects displayed I may mention a resto-
