The entrance to the harbour of Aberdeen is naturally bad, owing to a bar at the mouth of the river, where, at ebb-tide, the depth of water was often not more than two feet. To remedy this evil was, from a very early period, the ardent desire of the citizens, and to some of their first efforts in this direction we have alluded in our notice of [Aberdeen Light-house]. But it is since the commencement of the seventeenth century that the most effective improvements have been made, amongst which we may name the erection of a bulwark on the south side of the entrance, and the removal of a great stone, called "Knock-Maitland," which lay nearly in the middle of the river, both of which were accomplished in succession; the first in 1608, and the latter in 1618. Between 1623 and 1658, the quay was extended eastward, towards Futtie; by which means a considerable portion of ground was redeemed below the Castle-hill, and is now covered with buildings. In 1755 an additional quay was built a good way further down, opposite the village of Torrie. In 1770, further improvements were projected; and, on a report from Mr. Smeaton, recommending the erection of a pier on the north side of the entrance, so that the influx of sand from the north might be prevented, and the removal of the bar effected, by confining the waters of the river Dee within narrower bounds, the work was commenced in 1775, and finished in less than six years. The length of this pier was twelve hundred feet, and it terminated in a round head of sixty feet in diameter. Owing, however, to a departure from Mr. Smeaton's plan, by which the pier was founded too far to the north, it was found that a heavy swell entered the harbour; and to obviate this formidable inconvenience, a bulwark was projected from the pier, to about one-third across the channel.
By these means considerable improvements were effected; but as the trade of the city increased, inconvenience was still felt from a deficiency of water on the bar; and Mr. Telford, having been consulted in 1810, on the means of remedying this evil, recommended that the pier should be extended, and that wet-docks should be formed in the harbour. These works were commenced forthwith, and the pier, carried on to the extent of nine hundred feet beyond the head of Smeaton's pier, and again finished with a round head, was completed in 1816. In the course of the following winter, however, this head was destroyed by the storms; but being rebuilt with a slope towards the sea, it has since stood without very material damage. A breakwater, extending to the length of eight hundred feet, was also built on the south side, by which the mouth of the channel was narrowed, and the entrance protected from the storms of the south-east. Wharfs were built along the south-west side of Futtie; the pier opposite Torrie was enlarged; and, latterly, the quay has been extended westward from the old quay-head; and by raising embankments on the Inches, a considerable range of quay-room has been gained there, which is connected with the town by a swivel-bridge, opposite Marischal-street. By all these combined measures, quay-room has been provided to the extent of about four thousand feet; a tide-harbour has been formed, in which, at spring-tides, the depth of water is about eleven feet at the west-end, gradually increasing to fifteen feet, where it joins the course of the river; while the depth of the water on the bar has been increased to about nineteen feet.
ABERDEEN LIGHTHOUSE.
Immediately to the south of the small bay of Greyhope stands the Girdleness Lighthouse; an erection by which the trade of Aberdeen has been greatly benefitted. The Girdleness, from which it takes its name, is a conspicuous promontory of which the Commissioners of the Northern Lights took advantage to erect this monitory beacon: it was lighted up for the first time on the night of the 15th of October, 1833, and is a lofty, circular tower, built of granite, and crowned with two copper domes, one within the other, in order to prevent the effects which would follow from the condensation of vapour from the heated air of the lamps. The dwelling-houses of the keepers are at the bottom of the tower; and a field of considerable extent has been walled in and cultivated for their accommodation. It is on the larboard, or left-hand side, as we enter the port, and is known to mariners as a double-light, a distinction produced by placing two lights in the same tower, the one above the other. Of these, the lower light is visible in clear weather at the distance of thirteen, and the higher at that of sixteen miles. They are under the charge of two keepers, one of whom mounts guard at sunset, and in case of emergency can summon assistance by means of an alarm-bell, placed in the sleeping apartments, which may be rung from the light-room, by means of an air-blast, through tubes laid for that purpose. This edifice, of incalculable benefit to the cause of humanity, was erected after the design of Robert Stevenson, Esq., and does great honour to his talents. The bay of Greyhope, above-named, is memorable as the scene of many a disastrous shipwreck, particularly that of the Oscar, in which, out of a crew of forty men, only two were saved. This occurred on the 1st of April 1813.
For many centuries after the foundation of Aberdeen, the harbour was nothing more than an open expanse of water, washing the base of the Castle-hill on the north, the rising grounds of Torrie on the south, and communicating with the sea by the narrow and shallow mouth of the river. Of this basin the greater part was left dry at ebb of tide; while several large, but low islands, were never wholly overflowed. The most ancient, and during many years the only erection within the port, was a bulwark extending from the Ship-row southwards, and now known as the Shore-area. Its extremity was called the Quay-head, a name afterwards applied to the wharfs extending from the vicinity of the Trinity Kirk eastward, beyond the present weigh-house. At what time it was built is altogether unknown; but it was in existence in the fourteenth century, and was probably constructed in the preceding age. In 1484, having become ruinous, it was either repaired or rebuilt; and about the same time, beacons for the guidance of ships were erected, and the wreck of a Spanish galley on the southern shore, which had long obstructed the channel, was removed. In 1512, the quay was again repaired; and in 1526, still further operations became necessary, and a great portion of the wharfs was reconstructed. In 1549, repairs being once more required, a stair was added; and in 1582 a crane was erected. In 1621, two corn-mills were built within flood-mark; and about thirteen years later, a weigh-house, which served also for a custom-house, was erected. In the course of the same century, various other additions were made to the wharf, and several municipal statutes introduced for the better regulation of the port. In 1566, a lighthouse, containing "three great flaming lights, to burn from daylight to daylight, between the first day of September and the last day of March," was erected on St Ninian's Chapel, on the Castle-hill.
