12 NOKTHWESTERN BOUNDARY OF UNITED STATES. [bull. 17 1. 
the Northwest Boundary Commission, deposited by me in the Department at the 
close of the work in October, 1869. 
I have therefore the honor to request that you allow me to withdraw these records 
and papers temporarily. Before leaving for the field they will be returned to the 
Department, 
I have the honor to be, very respectfully, your obedient servant, 
Archibald Campbell, 
Commissioner, Northern Boundary Survey. 
Hon. Chas. Hale, 
Acting Secretary of State. 
Upon that letter is indorsed: "Papers, etc., herein referred to sent 
to Mr. Campbell 27th June.*' 
A search of the records of the Index Bureau of the State Depart- 
ment fails to reveal any other entry touching these papers. If they 
were returned no record was made of such return. It is certain that 
these papers were in the possession of the Northern Boundary Com- 
mission in 1872. Beyond that there is no trace. It would therefore 
be natural to look for them among the papers of the Northern Bound- 
ary Commission, which were sent to the State Department on June 
30, 1870. But a search among these papers made by me in March, 
1900, was unsuccessful. The missing manuscript was not found. 
Prof. C. L. Doolittle, now at the Flower Observatory at Upper 
Darby, Pennsylvania, was connected with the Northern Boundary 
Survey. In response to an inquiry as to whether he had any informa- 
tion touching the report desired, he writes, among other things, under 
date of March 12, 1900: 
My connection with the northern boundary began after active operations had been 
going on for a year. We then had our office at Detroit. After field operations were 
completed we removed to Washington. It is not a great exaggeration to say that I 
saw every scrap of paper to be found in the Detroit office. At all events, this report 
was not to be found there. I remember hearing such a report spoken of, but it was 
then said to be stored away with other Government archives at Washington. 
(c) Archibald Campbell, the commissioner, died in the city of Wash- 
ington July 27, 1887. To his son, Charles Campbell, now an employee 
in the Department of State, I am indebted for information as to the sur- 
vey. I have also conferred with Gen. J. G. Parke, Corps of Engi- 
neers, U. S. A. (retired), who was chief astronomer and surveyor of 
the Northwestern Boundary Survey Commission, and with Mr. William 
J. Warren, chief clerk in the office of the Chief of Engineers, U. S. A., 
who was secretary of the commission. To both of these gentlemen, 
and especially to the latter, I am indebted for information used in pre- 
paring this account. Mr. G. Clinton Gardner, the assistant astrono- 
mer and surveyor from 1857 to 1868, is now a civil engineer in Peru, 
South America, while Mr. Joseph S. Harris, general assistant North- 
west Boundary Survey from 1857 to 1861, is now president of the 
Philadelphia and Heading Railroad. To both of these gentlemen I am 
indebted for letters relating to the boundary and its survey. I have
