So much of the property of James Smithson as has been received in
money, and paid into the Treasury of the United States, being the
sum of $541,379.63, shall be lent to the United States Treasury and
invested in public debt securities with maturities requested by the
Smithsonian Institution bearing interest at rates determined by the
Secretary of the Treasury, based upon current market yields on
outstanding marketable obligations of the United States of
comparable maturities, and this interest is hereby appropriated for
the perpetual maintenance and support of the Smithsonian
Institution; and all expenditures and appropriations to be made,
from time to time, to the purposes of the Institution shall be
exclusively from the accruing interest, and not from the principal
of the fund. All the moneys and stocks which have been, or may
hereafter be, received into the Treasury of the United States, on
account of the fund bequeathed by James Smithson, are hereby
pledged to refund to the Treasury of the United States the sums
hereby appropriated.
