APPENDIX.
No. I.
The preceding sheets having been submitted to my friend
Mr. Charles Thomson, Secretary of Congress, he has
furnished me with the following observations, which have too
much merit not to be communicated:
(1.) p. 15. Besides the three channels of communication mentioned between the western waters and the Atlantic, there are two others, to which the Pennsylvanians are turning their attention; one from Presque Isle on Lake Erie, to Le Bœuf, down the Alleghaney to Kiskiminitas, then up the Kiskiminitas, and from thence, by a small portage, to Juniata, which falls into the Susquehanna: the other from Lake Ontario to the East Branch of the Delaware, and down that to Philadelphia. Both these are said to be very practicable: and, considering the enterprising temper of the Pennsylvanians, and particularly of the merchants of Philadelphia, whose object is concentered in promoting the commerce and trade of one city, it is not improbable but one or both of these communications will be opened and improved.
(2.) p. 18. The reflections I was led into on viewing this passage of the Patowmac through the Blue Ridge were, that this country must have suffered some violent convulsion, and that the face of it must have been changed from what it probably was some centuries ago: that the broken and ragged faces of the mountain on each side of the river; the tremendous rocks, which are left with one end fixed in the precipice, and the other jutting out, and seemingly ready to fall for want of support; the bed of the river for several miles below obstructed, and filled with the loose stones carried from this mound; in short, every thing on which you cast your eye evidently demonstrates a disrupture and breach in the mountain,
