Archibald Campbell, iIk 1 commissioner; one i>\ Gen. J. (i. Parke, 
chief astronomer and surveyor; one by G. Clinton Gardner, assistant 
astronomer and surveyor, and one l»\ J. S. Harris, general assistant. 
For this description of the missing manuscript I am indebted to Mr. 
William J. Warren, Bureau of Engineers, War Department. When 
Captain Wheeler was preparing his account of this survey he made an 
unsuccessful search for this missing report. He says: 1 
I have been unable to trace the manuscript of the final report, including that of 
the chief astronomer and the specialists, which it is believed was made. According 
to the Journal of the Senate of February 9, L871, this reporl was called for bythe 
Senate, but a search of the Senate records and also those of the State Department, 
made al my request by Mr. Dwight, librarian of the State Department, remained 
unavailing on June L5, L887. Mr. William . I. Warren, secretary of the commissioner 
[and] now chief clerk [in the office] of the [Chief of] Engineer[s] [War] Depart- 
ment, recollects to have seen the manuscripl of this reporl a1 the office of the North- 
ern Boundary [Survey], established in L873, as does also Maj. J. V. Gregory, Corps 
of Engineers, a member of thai commission, bu1 it could not be found by Mr. Dwighl 
in the records transmitted at the close of the latter survey to the state Department. 
The search above mentioned ! have now repeated and with like 
result. The manuscript has not been found. 
The existence of the manuscript isattested by Mr. Warren, who gave 
me the description above written. The call for it made by the Senate 
in L871 is set forth in the following extract from the Senate Journal 
of February 9, 1*71. page 25 !: 
Mr. Howard [Jacob M., of Michigan] submitted the following resolution, which 
was considered by unanimous consent, and agreed to: 
II Resolved, That the President he respectfully requested, if not incompatible with 
the public interests, to transmit to the Senate copies of the final report, and the 
accompanying documents, of the commissioner on the part of the United stale.- to 
carry into effect the first article of the treaty with Great Britain of June L5, L846." 
An examination of the records in the office of the Secretary of the 
Senate reveals no other entry concerning it. from which it is concluded 
thai it wa> never sent. Similarly an examination of the records in the 
Index Bureau of the State Department shows the call, bul no action is 
indorsed thereon, thus corroborating the belief that it was not sent. 
When the Northern Boundary Commission was created, in hs7i>, 
Mr. Archibald Campbell was appointed United States commissioner 
of that survey also. He found at the outset that it was desirable i<> 
have for reference the records of the Northwestern Boundary Survey, 
and accordingly wrote to the State Department asking permission to 
withdraw those records for temporary use. 
The follow in g i- a copy of his Letter, which is now on file in the 
Index Bureau of the State Department: 
I', s. Northern Boundary Commission, 
Washington, l>. C, June 
Sir: In preparing for the duties of the boundarj commission it would he of the 
greatest assistance to have the use of the records, notebooks, and other papers of
