While on these two voyages, the author rowed over
five thousand miles, meeting with but one accident,
the overturning of his canoe in Delaware Bay.
He returned to his home with his boats in good
condition, and his note-books, charts, &c., in an
excellent state of preservation.

At the request of the "Board on behalf of the
United States Executive Department" of the
Centennial Exhibition at Philadelphia, the paper canoe
"Maria Theresa," and the cedar duck-boat "Centennial
Republic," were deposited in the Smithsonian
Department of the United States Government
building, during the summer and fall of 1876.

The maps, which show the route followed by
the paper canoe, have been drawn and engraved
by contract at the United States Coast Survey
Bureau, and are on a scale of 1/1,500,000. As the work
is based on the results of actual surveys, the
maps may be considered, for their size, the most
complete of the United States coast ever presented
to the public.

Much credit is due to Messrs. Waud and Merrill
for the artistic results of their pencils, and to Messrs.
John Andrew & Son for their skill in engraving the
illustrations.
