BOUNDARIES, AREAS, GEOGRAPHIC CENTERS AND ALTITUDES OF THE UNITED STATES
AND THE SEVERAL STATES
WITH A BRIEF RECORD OF IMPORTANT CHANGES IN
The first edition of the record setting forth the history of the boundaries of the United States and the several States and Territories was prepared by Henry Gannett, assisted by Franklin G. Butterfield, and was published as Bulletin 13 of the United States Geological Survey in 1885. The second edition, revised and enlarged by Henry Gannett, was published as Bulletin 171 in 1900. The third edition, also revised by Henry Gannett, was published as Bulletin 226 in 1904. A reprint of this edition with minor corrections was issued in 1906.
The present bulletin is a revision and enlargement of Bulletin 226 and includes additional matter incidentally connected with boundaries.
It is the desire of the Geological Survey to make this publication a complete record, and therefore suggestions for the addition of any germane material will be welcomed.
