James River, Va., is formed by the conflu-
ence of Jackson and Cowpasture Rivers, which
rise in the Alleghany Mts., and run in S. W.
courses, nearly parallel to each other, for about
50 miles, until they form a junction near the
N. W. angle of Bottetourt co. The river here
assumes a S. course for a few miles, and receives
Craig's Creek from the S. It then takes a more
easterly direction, bearing first S. E., then N. E.,
about 35 miles, to the W. base of the Blue
Ridge, where it receives the North River from
Augusta co. Here the river begins to break
through the Blue Ridge, and, being now a fine
navigable stream, it traverses a gap in this moun-
tain range about 15 miles N. E. of the Peaks of
Otter. Its general course through the mountains
is S. E., in which course it continues for 30 miles
farther, forming the dividing line between Am-
herst co. on the N. and Bedford and Campbell
counties on the S. Here, traversing another lat-
eral chain of mountains, the river is inflected to
the N. E., and pursues this course 40 miles, be-
tween Amherst and Nelson counties on the N.,
and Appomattox and Buckingham on the S. It
then assumes a course a little S. of E., which it
pursues in general about 70 miles, to the head
of tide water, separating Albemarle, Fluvanna,
Goochland, and Henrico counties on the left,
from Buckingham, Cumberland, Powhattan, and
Chesterfield on the right. It receives the Appo-
mattox River from the S. at City Point, 34 miles
below Richmond. This is the largest tributary
of James River, being about 150 miles long, and
navigable for large merchant vessels 20 miles, to
Petersburg, and for boats through nearly its
whole course. After meeting the tide, James
River increases considerably in width, and con-
tinues by comparative courses about 100 miles
in a S. E. course, until it passes through Hamp-
ton Roads, and merges in Chesapeake Bay,
between Old Point Comfort and Point Willough-
by. The whole distance from the farthest source
of James River in the Alleghany Mts., to its
mouth, following all the windings of the stream,
is about 500 miles. Its comparative length
through the centre of its valley is about 370
miles. A line drawn in a S. S. W. direction from
Old Point Comfort to the Alleghany Mts. 225
miles, will pass very nearly through the centre
of that portion of the valley of James River
which* lies E. of the mountains. Its broadest
part, including those of its confluents, is W. of
the mountains, where it has a width of 90 miles ;
but the mean width of the entire valley is about
45 miles, and its area something over 10,100
square miles. Lynchburg on the S. side, and
Richmond on the N., are the principal places
on James River. The river is navigable for ships
of large size as far as Jamestown. Vessels of
200 tons may go up to Warwick, and of 120 tons
to Rockets, the port of Richmond. 110 miles
from its mouth. Here are falls which entirely
obstruct ship navigation. A canal, however,
connects the tide waters below with the boatable
waters above the falls, at Richmond, which are
thence navigable for bateaux 220 miles. The
first English settlement in the United States was
made on this river in 1608. It was on a point
of land projecting into the river from the north
side, 32 miles from its mouth. A few ruins are
all that now remain of this ancient and once
