New wharves were at the same time constructed inside the harbour; a new channel for the river was excavated, which further enlarged the floating space and wharf accommodation; wet and dry docks were added; until at length the quay berthage amounted to not less than 6290 feet, 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; an excellent tidal harbour was formed, in which, at spring tides, 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: shipbuilding had made rapid progress; Aberdeen clippers became famous, and Aberdeen merchants carried on a trade with all parts of the world; manufactures of wool, cotton, flax, and iron were carried on with great success; its population rapidly increased; and, as a maritime city, Aberdeen took rank as the third in Scotland, 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, also situated on the east coast of Scotland, at the entrance to the Frith of Tay. There are those still living at the place who remember its former haven, consisting of a crooked wall, affording shelter to only a few fishing-boats or smuggling vessels--its trade being then altogether paltry, scarcely deserving the name, and its population not one fifth of what it now is. Helped by its commodious and capacious harbour, it has become one of the most populous and thriving towns on the east coast. [Image] Plan of Dundee Harbour. The trade of the place took a great start forward at the close of the war, and Mr. Telford was called upon to supply the plans of a new harbour. His first design, which he submitted in 1814, was of a comparatively limited character; but it was greatly enlarged during the progress of the works. Floating docks were added, as well as graving docks for large vessels. The necessary powers were obtained in 1815; the works proceeded vigorously under the Harbour Commissioners, who superseded the old obstructive corporation; and in 1825 the splendid new floating dock--750 feet long by 450 broad, having an entrance-lock 170 feet long and 40 feet wide--was opened to the shipping of all countries.
