1859 edition. Excerpt: ...one already mentioned between Pittsburg
and Erie, affording very little comfort or facility to those who
have the misfortune to be obliged to travel upon them. But on the
construction of one or two lines of road, the Americans have
bestowed a little more attention. The most remarkable of them is
that called the "National Koad," stretching across the country from
Baltimore to the State of Illinois, a distance of no less than 700
miles, an arduous and extensive work, which was constructed at the
expense of the government of the United States. The narrow tract of
land from which it was necessary to remove the timber and brushwood

Ohio and Indiana, to Illinois. It is in contemplation to produce
this line of road to the Mississippi at St Louis, where, the river
being crossed by a ferry-boat stationed at that place, the road is
ultimately to be extended into the State of Missouri, which lies to
the west of the Mississippi. The "Macadamized road," as it is
called, leading from Albany to Troy, is another line which has been
formed at some cost, and with some degree of care. This road, as
its name implies, is constructed with stone broken, according to
Macadam's principle. It is six miles in length, and.has been formed
of a sufficient breadth to allow three carriages to stand abreast
on it at once. It belongs to an incorporated company, who are said
to have expended about L.20,000 in constructing and upholding
it....
