10 NORTHWESTERN BOUNDARY OF UNITED STATKS. [bill. 174. 
(b) Manuscript records in the State Department, consisting of the 
original notebooks, observations, computations, plattings, sketches, 
maps, correspondence, etc. 
(c) The memories of some of the surviving participants in the survey. 
These will be discussed in the order indicated above. 
(a) In the Statutes at Large are contained all laws enacted by Con- 
gress touching the boundary, including also all the treaties. For the 
original treaty of June 15, 1816, see vol. 9, pages 869-870; for the 
act creating the commission to survey and mark the boundary, vol. 11, 
page, 42; for various appropriation acts, vol. 11, pages 42, 159, 312, 
403, and vol. 12, page 20. 
On November 12, 1859, Lieut, (now Gen.) John G. Parke, chief 
astronomer and surveyor, made a short report of progress. This is a 
document of 7 pages and is printed as Senate Ex. Doc. No. 16, Thirty- 
sixth Congress, first session. It is here reprinted as Appendix B. 
Nothing further, in official documents, appears for nine years. The 
civil war turned attention to more urgent matters and this subject was 
dropped. In February, 1868, however, President Johnson sent to the 
Senate a long communication on the San Juan boundary question. 
This document (Senate Ex. Doc. No. 29, Fortieth Congress, second 
session) of 280 pages, though dealing chiefly with the water boundary, 
nevertheless throws considerable light on the history of the land 
boundary. 
On January 13, 1869, the House of Representatives, by a resolution, 
requested information as to expenditures by the Northwestern Bound- 
ary Commission. In response, a message from President Johnson 
was laid before the House of Representatives on February 13, 1869. 
(House Ex. Doc. No. 86, Fortieth Congress, third session.) This 
document of 102 pages is almost wholly given to a detailed tabular 
exhibit of expenditures. There is, however, a letter of 4 pages from 
the commissioner, Hon. Archibald Campbell, summarizing the entire 
history of the survey. This is apparently the nearest approach to a 
report on this subject that has ever appeared in print. 
Finally, in 1889, Capt. George M. Wheeler, U. S. A., published in 
his report upon geographical surveys west of the one hundredth 
meridian (vol. 1, pp. 614-619) a short account of the Survey of the 
Northwestern Boundary of the United States 1857-1861. 
(b) The manuscript records of the survey are nearly all contained in 
two blue chests stored in the division of manuscripts in the library of 
the State Department. Some of the maps being too large to go into 
these chests are kept elsewhere in the library. The memoranda, notes, 
correspondence, maps, etc., in this collection are the chief source of 
information from which this account has been prepared. But unfor- 
tunately the most important document of all was not found there, and 
a diligent search has failed to bring it to light. This paper is the final 
report, written on foolscap paper and consisting of four parts, one by
