One of the prominent commissions of which Mr. Clark 
was a member was that named in the act of August 2,1876, 
for the completion of the Washington National Monument, 
of which the other members were the President, the Chief 
of Engineers of the Army, the Supervising Architect of the 
Treasury, and the first vice-president (Mr. Corcoran) of the 
Washington National Monument Society, and on which he 
served until the monument was finished. 
Another of these commissions of which he was a member 
was that for the construction of the building for the Library 
of Congress, under whom the work was begun in 1887-1888. 
The other members were the Secretary of the Interior and 
the Librarian of Congress. 
At the time of his death Mr. Clark was a fellow of the 
Clarendon Historical Society of Edinburgh and of the Amer¬

logical Institute of America, the American Association for 
the Advancement of Science, the Franklin Institute, the 
Washington National Monument Society, and the American 
Forestry Association, as well as the Philosophical Society. 
He was also a trustee of the Corcoran Gallery of Art and 
the only surviving member of the original board of trustees 
of that institution, having been a close friend of the founder, 
William W. Corcoran. He served for years on the art commit¬ 
tee and was chairman of the special committee in charge of 
the erection of the present New Gallery. In business inter¬ 
ests in the city he was president for many years of the Na¬

gave much more than his full share of private and public 
aid to charity, including his valuable architectural services 
in connection with buildings for charitable institutions. 
Trained in boyhood by his uncle Thomas to read and

reader, and his love of and acquaintance with architect¬
