The number of elevations within the territory watered by the Aroostook and claimed by Great Britain that have thus been carefully measured amounts to upward of 200.

This survey shows that although the prominent eminences which occur along that portion of the “axis of maximum elevation” of Messrs. Mudge and Featherstonhaugh which lies between the mouth and the source of the Aroostook correspond very nearly in height and position by our measurements with those reported by themselves, yet these eminences are separated one from another by spaces of comparatively low and very often swampy country, so extended as to preclude the idea of a continuous range of highlands in the direction represented upon the map of those commissioners.

If a range or chain of highlands is to be made to appear by drawing a strongly marked line over widely extended valleys or districts of comparatively low country so as to reach and connect the most prominent eminences which may fall within the assumed direction, then such a range or chain of highlands may here be made as plausibly in any other direction as in that chosen by Messrs. Mudge and Featherstonhaugh, for the detached elevated peaks are so distributed as under such a principle to favor any one direction as much as another, and might thus be made to subserve in an equal degree whatever conflicting theories the object in view might cause to be originated.

We may also refer, in further illustration of the character of the country through which a portion of this pretended “axis of maximum elevation” is made to pass, to a panorama view taken in October, 1841, by one of Major Graham’s assistants from the summit of Blue Hill, where crossed by the true meridian of the monument, at the source of the St. Croix.  This position is 1,100 feet above the level of the sea and 47-1/2 miles north of the monument.  It commands a most satisfactory view of the whole country embraced within a radius of 40 to 60 miles, including, as the landscape shows, Parks Hill to the south; Katahdin, the Traveller, and Mars Hill to the southwest; Quaquajo, the Horseback, the Haystack, and one or two peaks beyond the Aroostook to the west; the heights upon the Fish River and the southern margin of the Eagle Lakes to the northwest, and those south of the St. John (except a small angle obstructed by the Aroostook Hill) to the north.

The character of the great basin of the Aroostook, dotted with the detached peaks which rise abruptly from it at intervals of many miles apart, is here exhibited through at least two-thirds of its extent in so satisfactory a manner as in itself to preclude the idea of an “axis of maximum elevation” composed of anything like a connected or continuous chain in this region of country.
