er the termination of
the commission with which you are charged for the publication
of the maps and charts of the Amazonian regions.

"For this reason, you will be pleased to deliver to Mr.
Freyre, Minister of Peru in Washington, the referred to
charts, maps and all other articles belonging to the
Government of Peru, which now remain in charge of the
Commission over which you preside; all to be delivered under
inventories and with the necessary forms.

"In regard to the payment of the salaries of yourself and the
other gentlemen who form part of the Commission, I have
ordered the Minister of the Treasury to take measures for the
prompt disbursement of what may be due, and I judge that in a
short times these claims will be completely satisfied.

"With my best wishes, it gives me pleasure to repeat the
expression of my friendship and particular esteem.

"Truly your faithful Servt.,
"PARDO."

In compliance with the directions of President Pardo, the charts made
by the Commission were delivered to the Peruvian Legation at
Washington. These charts were all ready for publication, and had they
been published would have afforded much valuable information in regard
to the Upper Amazon and its tributaries, water courses which are daily
becoming more and more important to commerce, and which are destined
in the not distant future to be navigated by lines of ocean as well as
by lines of river steamers.

The following letter from Colonel Manuel Freyre, Peruvian Minister at
Washington, describes the charts and plans which Tucker delivered to
the Legation, and which it is to be hoped are still preserved:

"_Legacion del Peru._
