a bulwark was projected from it�察�so as to occupy about one third of
the channel entrance。
The trade of the place continuing to increase�察�Mr。 Rennie was
called upon�察�in 1797�察�to examine and report upon the best means of
improving the harbour�察�when he recommended the construction of
floating docks upon the sandy flats called Foot Dee。 Nothing was
done at the time�察�as the scheme was very costly and considered
beyond the available means of the locality。 But the magistrates
kept the subject in mind�察�and when Mr。 Telford made his report on
the best means of improving the harbour in 1801�察�he intimated that
the inhabitants were ready to cooperate with the Government in
rendering it capable of accommodating ships of war�察�as far as their
circumstances would permit。
In 1807�察�the south pier´head�察�built by Smeaton�察�was destroyed by a
storm�察�and the time had arrived when something must be done�察�not
only to improve but even to preserve the port。 The magistrates
accordingly proceeded�察�in 1809�察�to rebuild the pier´head of cut
granite�察�and at the same time they applied to Parliament for
authority to carry out further improvements after the plan
recommended by Mr。 Telford�察�and the necessary powers were
conferred in the following year。 The new works comprehended a
large extension of the wharfage accommodation�察�the construction of
floating and graving docks�察�increased means of scouring the harbour
and ensuring greater depth of water on the bar across the river's
mouth�察�and the provision of a navigable communication between the
Aberdeenshire Canal and the new harbour。

The extension of the north pier was first proceeded with�察�under the
superintendence of John Gibb�察�the resident engineer�察�and by the
year 1811 the whole length of 300 additional feet had been
completed。 The beneficial effects of this extension were so
apparent�察�that a general wish was expressed that it should be
carried further�察�and it was eventually determined to extend the
pier 780 feet beyond Smeaton's head�察�by which not only was much
deeper water secured�察�but vessels were better enabled to clear the
Girdleness Point。 This extension was successfully carried out by
the end of the year 1812。 A strong breakwater�察�about 800 feet long��
was also run out from the south shore�察�leaving a space of about 250
feet as an entrance�察�thereby giving greater protection to the
shipping in the harbour�察�while the contraction of the channel�察�by
increasing the ;scour�察─�tended to give a much greater depth of
water on the bar。

The outer head of the pier was seriously injured by the heavy
storms of the two succeeding winters�察�which rendered it necessary
to alter its formation to a very flat slope of about five to one
all round the head。*��9��

New wharves were at the same time constructed inside the harbour��
a new channel for the river was excavated�察�which further enlarged
the floating space and wharf accommodation�察�wet and dry docks were
added�察�until at length the quay berthage amounted to not less than
6290 feet�察�or nearly a mile and a quarter in length。 By these
combined improvements an additional extent of quay room was
obtained of about 4000 feet�察�an excellent tidal harbour was formed��
in which�察�at spring tides�察�the depth of water is about 15 feet��
while on the bar it was increased to about 19 feet。 The prosperity
of Aberdeen had meanwhile been advancing apace。 The city had been
greatly beautified and enlarged�此�shipbuilding had made rapid
progress�察�Aberdeen clippers became famous�察�and Aberdeen merchants
carried on a trade with all parts of the world�察�manufactures of
wool�察�cotton�察�flax�察�and iron were carried on with great success��
its population rapidly increased�察�and�察�as a maritime city�察�Aberdeen
took rank as the third in Scotland�察�the tonnage entering the port
having increased from 50��000 tons in 1800 to about 300��000 in
1860。
Improvements of an equally important character were carried out by
Mr。 Telford in the port of Dundee�察�also situated on the east coast
of Scotland�察�at the entrance to the Frith of Tay。 There are those
still living at the place who remember its former haven�察�consisting
of a crooked wall�察�affording shelter to only a few fishing´boats or
smuggling vesselsits trade being then altogether paltry�察�scarcely
deserving the name�察�and its population not one fifth of what it now
is。 Helped by its commodious and capacious harbour�察�it has become
one of the most populous and thriving towns on the east coast。

The trade of the place took a great start forward at the close of
the war�察�and Mr。 Telford was called upon to supply the plans of a
new harbour。 His first design�察�which he submitted in 1814�察�was of
a comparatively limited character�察�but it was greatly enlarged
during the progress of the works。 Floating docks were added�察�as
well as graving docks for large vessels。 The necessary powers were
obtained in 1815�察�the works proceeded vigorously under the Harbour
Commissioners�察�who superseded the old obstructive corporation�察�and
in 1825 the splendid new floating dock750 feet long by 450 broad��
having an entrance´lock 170 feet long and 40 feet widewas opened
to the shipping of all countries。

Footnotes for Chapter IX。
*��1�А�Hugh Millar�察�in his 'Cruise of the Betsy��' attributes the
invention of columnar pier´work to Mr。 Bremner�察�whom he terms ;the
Brindley of Scotland。; He has acquired great fame for his skill in
raising sunken ships�察�having warped the Great Britain steamer off
the shores of Dundrum Bay。 But we believe Mr。 Telford had adopted
the practice of columnar pier´work before Mr。 Bremner�察�in forming
the little harbour of Folkestone in 1808�察�where the work is still
to be seen quite perfect。 The most solid mode of laying stone on
land is in flat courses�察�but in open pier work the reverse process
is adopted。 The blocks are laid on end in columns�察�like upright
beams jammed together。 Thus laid�察�the wave which dashes against
them is broken�察�and spends itself on the interstices�察�where as��
if it struck the broad solid blocks�察�the tendency would be to lift
them from their beds and set the work afloat�察�and in a furious
storm such blocks would be driven about almost like pebbles。
The rebound from flat surfaces is also very heavy�察�and produces
violent commotion�察�where as these broken�察�upright�察�columnar´looking
piers seem to absorb the fury of the sea�察�and render its wildest
waves comparatively innocuous。

excited extraordinary interest at the time�察�and met with a rapid
and extensive circulation。 But his exposure of kidnapping gave
very great offence to the magistrates�察�who dragged him before their
tribunal as having ;published a scurrilous and infamous libel on
the corporation�察─�and he was sentenced to be imprisoned until he
should sign a denial of the truth of his statements。 He brought an
action against the corporation for their proceedings�察�and obtained
a verdict and damages�察�and he further proceeded against Baillie
Fordyce ��one of his kidnappers�察�and others�察�from whom he obtained
200L。 damages�察�with costs。 The system was thus effectually put a
stop to。

description of the work�察 �is nothing better than loose sand and
gravel�察�constantly thrown up by the sea on that stormy coast��
so that it was necessary to consolidate the work under low water by
dropping large stones from lighters�察�and filling the interstices
with smaller ones�察�until it was brought within about a foot of the
level of low water�察�when the ashlar work was commenced�察�but in
place of laying the stones horizontally in their beds�察�each course
was laid at an angle of 45 degrees�察�to within about 18 inches of
the top�察�when a level coping was added。 This mode of building
enabled the work to be carried on expeditiously�察�and rendered it
while in progress less liable to temporary damage�察�likewise
affording three points of bearing�察�for while the ashlar walling was
carrying up on both sides�察�the middle or body of the pier was
carried up at the same time by a careful backing throughout of
large rubble´stone�察�to within 18 inches of the top�察�when the whole
was covered with granite coping and paving 18 inches deep�察�with a
cut granite parapet wall on the north side of the whole length of
the pier�察�thus protected for the convenience of those who might
have occasion to frequent it。;Mr。 Gibb's 'Narrative of Aberdeen

CHAPTER X。
CALEDONIAN AND OTHER CANALS。
The formation of a navigable highway through the chain of locks
lying in the Great Glen of the Highlands�察�and extending diagonally
across Scotland from the Atlantic to the North Sea�察�had long been
regarded as a work of national importance。 As early as 1773��
James Watt�察�then following the business of a land´surveyor at Glasgow��
made a survey of the country at the instance of the Commissioners
of Forfeited Estates。 He pronounced the canal practicable�察�and
pointed out how it could best be constructed。 There was certainly
no want of water�察�for Watt was repeatedly drenched with rain while
he was making his survey�察�and he had difficulty in preserving even
his journal book。 ;On my way home�察─�he says�察 �I passed through the
wildest country I ever saw�察�and over the worst conducted roads。;
Twenty years later�察�in 1793�察�Mr。 Rennie was consulted as to the
canal�察�and he also prepared a scheme�此�but nothing was done。 The
project was�察�however�察�revived in 1801 duri
