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 . ion of this joint commission, the chiefastronomers of the English and United States commissions were in accordin this view, that the parallel of latitude, as defined by astronomical obser-vation at successive points, was, for the pm-pose required, a true parallel,and the only one that would fulfiU the practical condition of being readilyrecovered. The question as presented, and which at the time gave rise tomuch discussion, was whether to define upon the groimd an astronomicalparallel of latitude, as above described, or a uniform line depending uponthe mean of the astronomical stations. The recommendation of the chiefastronomers was based on the following grounds: 1st, that the portion ofthe parallel of 49° included within the operations of the commission, beingonly about one-twentieth of the entire circle of latitude, was not sufficientto fix, with any mathematical accuracy, the true position of the mean line BOUNDARY COMMISSION DIAGRAM sh ovrmo ETHOOapTRAClNG PARALLEL.
