June 25, 1891.

Dear Mr. Marsh, -

Although it may not perhaps be reasonable at my age
to make a long voyage, I cannot resist the desire to see in place the results
of your admirable works. I have just written Mr. Emmons that I intend to go
to the Congress at Washington; and, if it is possible for a man of 63 years
to make the excursion to the Yellowstone Park, I shall go to see that curious
centre that you have all contributed to make illustrious. I am so unhappy
over the death of my wife who was the companion of all my works, that I have
need of diverting myself; I rejoice at the prospect of seeing you again, and
of admiring your collections.

We are wanting entirely in Paris information as to what is to be done
in Washington and on the excursions.
