ers of the Chesapeake and Ohio Canal,
to know that these contracts, covering
about IS miles of the canal, enlarged
from 4s to 60 in breadth, and from i've
to six feet IN depth, involve an expendi-
,ure, which is less than the estimate Of
the cost Of this work submitted to Con.

CATION OF the company TO supply water

that the water lime, already discovered

Falls TO within half mile of the knoc

quite $4,000 for aqueducts and culvert.
