We now come 10 the timber bridge, OF which there
is but one span up, lover the Navigation Co.'S canal
on the eastern side of the river. This work, as have
already remarked is to be- run over on tops the rails
will he IS feet above the surface OF the water In
w.
feet above that in the river. There IA one abdtment
and one pier finished, the remaining piers being Just
out of water, and the other abutments foundation
course has not vet been laid. The finished abutment,
Ike the piers Of the brick vaduc, is at right angles to
the lire Of the road while the pier completed (which
suppose will be similar TO the other when they are
fnsLeO is built parallel 10 the course of the stream.
Tie abntm mt is built entirely of stone laid 10 courses;
while the pier from the water up to the skewback-
some Al or d. fee-s also Of stone, with batter; and
ficm there up it is of brick, built ''plm, and bu. s1

work, which rs much heavier.
This span from center to center, if l6s feet built OF
three of HOses trusseS, placed feet apart In the
clear each truss s 90 feet high between top and bottom
chords Tie lower chord Is composed of tmbers,
two by Ii in and two by 16 in. while the upper
is Of three pieces IL by - in. and two by ~ in.
The panels are each II feet long and the pier pane
feet 70 great is the skew of this bridge that the
upper truss of this span hos lG panels the middle one
49, and the lower II. There are five l. nch verti
cal wrought iron rods to each of two panels both
ways from The ends the rods decrease in number,
for every two panels from both ends appro ich
the center Of the span. The horizontal braces be-
tween the lower chords by ill.,. placed angle
downward neither one being cut they cross one above
the other; this Is an improvement, as well as the
wrought iron connecting the continuous pieces of the
chords, where they abut one against another The
arch in this bridge has rise of some 40 feet, to within
feet inches Of the top chord Richard B. Osborne,
esq, is the able Chief EOgincer OF thir road.
Tat part of the Union Canal between this place
end within few miles of Lebanon it is intended to
enlarge TO the same dimensions a. the remainder OF
the work from Lebanon to Middetown, and of the
branch canal TO Pinegrove. II ia expected when the
widening of this the EASTERN Division is completed,
most of he lumber which is boated TO market from
along the North and West Branches of the Susquc-
hanna will 90 by here on its way to Philadelphia.
The course now is to continue down on the Susque-
hanna Canal to Chesapeake Bay, thence across the
pepinsuIa by the Delaware and Chesapeake Canal to
the Delaware, some forty miles below Philadelphia,
whence II is lowed TO the city.
When however, the work on the Union Canal IL
finished the large North and West Branch Canal boats
will be able TO run through it to this place, aud from
here TO Philadelphia by the Schuylkill Canal, which
also widened some ten years since.
The contractors in widening this end of the Union
Canal have commenced operations this season. The
high professional reputation of the Chief Engineer,
james Worral, esq., well as that Of lis Chief Aesis-
tant Mr. Hother llage, is surc guarantee that the
work will reflect credit upon themselves and the ASsis-
tant Engineers stationed along the line.
Tie Legislature of this State, during the Session
last ended incorporated the Reading and Iehigh Rail-
road to extend from here to Allentown; and at the
time write there is corps OF engineerr under charge

In doing this they placing the tracks six feet apart
so that ere long they will accommodate their passen-

the only objection to the otherwise comfortable apart
