short distance north Of this aqucduct the Tuckaho
canal of about 81 miles in length communicating wit
the Tuckahoe coal pits locks into the Tuckahoe creek
along which the boats navigating this canal pass int
the 4th level OF the J. & K. canal the guard loci
near Bosher's dam
Upon the sccond scct:on there are farm bridges on

A good deal Of rock excavation encountered or
this section; the remainder consisted OF clay, grave
ard sand
About half mile above Manakintown ferry road, ;
railroad of about quarter Of mile in length connect
ed with the Dover coal pits terminates upon the Nortl
side of the canal.
At the upper end of this section the canal is carried

The WIRES are circular and all the masonry with the
exception of the arch, coping and waterway Of the
parapets, which arc cat IS rubbe work. This aqnc

slight repairs to adapt it to the new canal
Upon the hrd section there II farm bridges, ono

and the other upon the plantation belonging to Doctor

Between Dover aqucduct and Judcs ferry road, the
construction of the canal has been rendered much
costly By the location of the stage road upon the nor!
bank Of the Old canal To give the proper dimensions
10 tn" cnnal, this road was necessarily thrown mic
the hill, which OccaSoncd GOOD deal Of deep cutting
aad rendered the construction Of Tic dItccs VIII cl

the water from the hill side and convey 1t 10 the
culvcr!s, much more expensive.
The clna is carried over Beaycrdam creek b. an
aGurduct Of the following construction
Seven piers and two ahutmcnts feet IN height are
built IL feet apart upon solid rock foundation to with

Over these piers and abutm"nts floor "a feet IN

to the height of IA feet These walls raised to this
unusual hcg ht to prevent the water from flowing over

was procured from quarry within one hundred yards
of tin aqncduc:, and The remainder from quarry about
one mile below The waterway OF the creek has been

limits were abandoned by the original contractors and
of them, after being relet to new contractors,
were again abandoned.
At Madcn's Adventure, dam constructed of tim

IS protected by guard lock.
