EDUCATION AND EXPLORATION 

 BY THE AMERICAN MUSEUM 



The report of President Henry Fairfield 

 Osborn, of the American Museum of Natural 

 History, for the year 1921 is a concise recountal 

 of the accomplishments of the institution and 

 records the firm establishment of the policy 

 inaugurated in 1917 — the policy of a broader 

 and more varied service calculated to prove of 

 scientific and educational value, not alone to 

 the citizens of New York, but also to those of 

 the entire nation. 



The most conspicuous event of the year last 

 past was a favorable attitude adopted by the 

 city administration toward this institution — 

 the decision to begin the construction of addi- 

 tional wings which have been urgently needed 

 for more than fifteen years, but which because 

 of the Ti^ar and the high cost of building imme- 

 diately following, it was found impracticable to 

 start before the current year. At a meeting 

 of the Board of Estimate and Apportionment, 

 held on December 26, 1921, the sum of 

 $1,500,000 was unanimously voted to erect the 

 southeast wing on Central Park West and the 

 southeast court building adjacent thereto as 

 planned in 1875. In providing these additional 

 halls, the city administration is liberally sup- 

 porting the public educational activities of the 

 museum's work. During the past year the 

 museum, which serves alike the schools of the 

 five boroughs, reached 1,500,000 school children, 

 869 natural history collections were in use 

 among the elementary schools. This is exclu- 

 sive of the number of lantern slides distributed 

 which illustrate the work of the museum in all 

 parts of the globe and provide the latest ac- 

 cepted methods of visual instruction in geog- 

 raphy, zoology, forestry and history, totaling 

 210,000, or a service of 182 schools. The num- 

 ber of schools reached outside the museum was 

 477 in all of the boroughs, and the number of 

 scholars was 1,247,515. By the methods initi-
