period 1842-1934, an average for the 92 years of less than $40,000 
a year. This does not include the cost of building and grounds 
of the new conservatory in 1927, $1,862,538, which would bring 
the average to about $58,500 per year. 
In 1921 Representative Langley introduced a bill (H. R. 2166, 
67th Congress, lst Session) ‘‘ To increase the area of the United 
States Botanic Garden.” Its removal from its old location on the 
Mall was necessitated by an Act of Congress locating the General 
Grant Memorial (completed about 1920) on the site of the Garden. 
The old site (about 12 acres) was between Maryland Avenue (on 
the West) and Pennsylvania Avenue (on the East) and the Cap- 
itol Grounds and Third St., S.W. The new site lies south of 
Maryland Avenue. 
This is chiefly an educational display garden, as the botanical 
research, herbarium, and botanical library are provided for under 
other branches of the Federal Government. In 1933 a new Con- 
servatory, costing $604,000, was completed on the corner of Mary- 
land Avenue and First Street, Southwest.
