The seacoast of the State of Maine is rugged and hilly. The primitive rocks of which its geological structure is chiefly composed are broken into ridges which run parallel to the great streams, and therefore in a direction from north to south. These ridges terminate in an irregular line, which to the east of the Penobscot may be identified nearly with the military road to Houlton. From the northern summit of these ridges an extensive view of the disputed territory can in many places be obtained. This is the case at the military post at Houlton, whence a wide extent of country may be seen. A still more perfect view may be obtained from the summit of Parks Hill, at a point about 400 yards south of the road from Houlton to Woodstock and about half a mile east of the exploring meridian line. At the time when that line was run by the British and American surveyors, under the fifth article of the treaty of Ghent, the top of this hill was covered with wood, and they were obliged to content themselves with the view from Park's barn, which is at least 200 feet beneath the summit. At the present moment the latter is cleared, and the view from west-southwest to northeast is unimpeded except by a single clump of trees, which cuts off the view for a few degrees in the northwest direction; but by a change of position every part of the horizon between these points is to be seen. Toward the west are seen ridges parallel to the Penobscot, over which Katahdin towers to a great height, bearing by compass N. 85° W. In a direction N. 75° W. are seen two distant peaks, one of which was identified as the Traveller. All of these eminences lie south of the line claimed by Great Britain. In the north-northwest direction there appear two ridges of comparatively small elevation, which were pointed out as the Aroostook Mountains, but have since been ascertained to lie near the sources of the Meduxnikeag. These lie in the line claimed by Great Britain in 1817. Between these and the other mountains there is evidently no connection, and the rest of the country, as seen from the hill, bears the aspect of a wooded plain. It will be sufficient to refer to this view to be satisfied that all the impressions which have been circulated of a continuous chain of elevations extending along the line claimed by Great Britain are utterly fallacious.
