"From the information I have received, there is a body of iron ore within seven or eight miles of the coal-bank; and I expect a very advantageous situation for water-works might be found at the confluence of the North Branch and the Savage. Among the great objects contemplated by the Patowmack Company in clearing the navigation of that extensive river, was that of forming an easy communication between the eastern and western waters, which you know are divided by the Allegany Mountains. The space that separates them at present is about sixty miles; but when the obstructions to the navigation down the Patowmack, which, passing through an extensive and fertile country, leads to the seat[Footnote: The writer means intended seat of federal empire.] of federal empire; and thence widening by degrees to the width of twelve miles, empties itself into the bay of Chesapeak.

DEAR FRIEND,
"In some part of the middle states, a climate similar to that of England may easily be found."
Inform our old acquaintance H——, that if he emigrates to America on the strength of this assertion of Cooper, (on which, you tell me he so much depends), he will, on his arrival, find himself egregiously mistaken. The sameness of latitude does not always indicate similarity of temperature: there are many other causes, which contribute to make this a very different climate from that of Great Britain.
The middle states of North America are hotter and colder at intervals, not only than England, but than any part of the Old Continent, under the same parallel of latitude.
Jefferson says, "Our changes from heat to cold are sudden and great. The mercury in Fahrenheit's thermometer has been known to descend from 92 to 47, in thirteen hours."
