Professor Hayden was ever heard of in connection with
that measure. When he returned to Washington in 1871,
he brought with him a large number of specimens from
different parts of the Park, which were on exhibition in
one of the rooms of the Capitol or in the Smithsonian Institute
(one or the other), while Congress was in session,
and he rendered valuable services, in exhibiting these specimens
and explaining the geological and other features of
the proposed Park, and between him, Langford and myself,
I believe there was not a single member of Congress
in either House who was not fully posted by one or the
other of us in personal interviews; so much so, that the
bill practically passed both Houses without objection.

It has always been a pleasure to me to give to Professor
Hayden and to Senator Pomeroy, and Mr. Dawes of Mass,
all of the credit which they deserve in connection with
the passage of that measure, but the truth of the matter
is that the origin of the movement which created the Park
was with Hedges, Langford and myself; and after Congress
met, Langford and I probably did two-thirds, if not
three-fourths of all the work connected with its passage.

I think that the foregoing letter contains a full statement
of what you wish, and I hope that you will be able
to correct, at least to some extent, the misconceptions
which the selfish vanity of some people has occasioned on
the subject.

Very truly yours,
