1849 Excerpt: ...of the rising water at the Light House rapidly
communicated to the water at the Custom House. Should this position
prove correct, the ebb tide can have no power on the Bar beyond the
force derivable from its weight of water, with the generally
trivial aid of the stream of the Liffey. Supposing it practical to
remove the Bar, the cause of its formation must likewise be
obviated, to secure any permanent advantage from such removal.
Another Engineer, indeed, in his observations on the drift of sand
on the Bar when disturbed by shoal scrubbers, found that in various
winds, the first ofc the flood carried the sand towards Sutton;
that in the progress of the flood tide the sand was carried
northward, directly upon the North Bull; and lastly, in a
north-west direction towards Clontarf; but at no time of the flood
was it carried into the Harbour. It is not less fortunate than
singular, that an east or south-east wind did not aid a flood tide
in carrying some portion of the agitated sand into the River; but
perhaps a phenomenon so propitious to a favorite theory, may at
some future pei iod submit to the ordinary laws of nature. The
report of the Directors General of Inland Navigation, (December,
1814) states, that comparing the survey of Captain Bligh with the
chart of Messrs. Scale and Richards, they found that although the
water in the Bar had increased, yet that the passage to the
northward of it, called the East Channel, which in 1/65 had 7 feet
water, was, in 1800, so choaked up as scarcely to leave a trace of
it. And on the same authority, we learn between the survey of
Captain Collins, in 1711, and that of Captain Bligh, in 1800, the
Bar had shifted its position upwards of half a mile to the
westward. They add, that the sand had not increased in the Bay in
