Reports upon the survey of the boundary between the territory of the United States and the possessions of Great Britain from the Lake of the woods to the summit of the Rocky mountains . ervations, with a sextant. It was in a prominent and convenient position for connecting with thepoint marked observatory, and with the most northwestern point, involv-ing no timber cutting. Confirmatory evidence in the shape of a letter from Mr. Barclay, Com-missioner of the Commission of 1824, who describes the original monumentas having been an oaken center post, surrounded by a crib-work of logsseven feet square. This coincides with the description, given by the Indians, of the mon-ument, and accounts for the relative positions of the depressions discoveredby Major Farquliar. As the evidence that the traces found were those ofthe remains of the old monument was considered satisfactory, the site wasaccepted by the Chief Astronomers of the Joint Commission, and a stationthere erected was connected with the due south line through the NorthwestPoint, and with the astronomical station, by means of a triangle whosebase-line, upon the opposite slioro of the bay, was tliree times carefully.

Tlie correction to the measured angles is all applied to theangle at the monument, because that angle was measured with a six-inchNegus theodolite, with verniers, whose least count was thirty seconds, andthe angles at the base-stations were measured by careful repetitions, withan eight-inch Wiirdemann transit, with verniers reading to ten seconds. It was agreed between the Chief Astronomers of the British and UnitedStates Commission, that the due south line should be laid off jointly. Observations for azimuth of the base-line were made by CaptainAnderson, upon Polaris near elongation, and by myself, upon Polaris atgreatest eastern and western elongations.
