navigation.
The object of my Invention is to provide in such cases a port, harbour,
or landing stage at a sufficient distance from the shore to be clear of
such obstructions, and yet in safe communication with the shore during 5
all weathers. I effect this by constructing at sea or at a suitable distance
from the shore a pier or harbour or landing stage, with one or more
shafts or towers communicating with the shore by a subway or tunnel
formed under the bed of the water. I place in the shafts suitable
staircases, lifts,-or-tackle,-by-which-communication-between-the-subway-1
and the landing stage or pier is effected.
The pier, harbour, or landing stage may be built in masonry or formed
of piles and framing, according to any of the known methods of
construction adopted for marine works.

filed by the said Robert Richardson in the Great Seal Patent Office
on the 24th August 1870.
