Within the last two centuries both these springs have repeatedly disappeared and been recovered, and always retaining their chalybeate qualities till of late. Within the last few years, however, while digging upon the adjacent eminence for the foundations of the west wing of the new infirmary, it would seem as if the course of the water had been disturbed, or some other change produced, the consequence of which is, that now the larger spring appears to possess hardly any chalybeate impregnation, whilst the smaller one is much weaker than formerly. [Illustration: ABERDEEN, FROM ABOVE THE CHAIN BRIDGE.] ABERDEEN, FROM ABOVE THE CHAIN BRIDGE. "Blyth Aberdein! thou beriall of all tounis, The lamp of bewtie, bountie, and blythnes; Unto the heaven ascendit thy renown is Off vertew, wisdom, and of worthines; Benottit is thy name of nobilnes;-- Be blyth and blissful, burgh of Aberdein!"--DUNBAR. The Port of Aberdeen is now universally known among seafaring men as one of the safest and most commodious in Scotland. The skill and practical efforts of both Smeaton and Telford were successively employed upon it; and after an arduous and extensive enterprise, the grand object has been fully obtained. To those who are only acquainted with the harbour under its present aspect it will be difficult to convey a correct notion of its appearance in ancient times. There is reason to suppose that at a period beyond the reach of history, the river Dee must have discharged its waters into the sea at the Craiglug--where the Chain Bridge is seen in the engraving--and that by their alluvial deposits, and the effects of the north-east winds, in accumulating the sands in the neighbourhood, the ground now occupied by the village of Footdee, the shorelands and Sandilands, the Links and the islands in the estuary were gradually raised above the level of the sea. At a less remote period it is believed that the river Don poured its floods into the frith of the Dee: and the conjecture derives strength from the notices of Roman geographers. The occurrence of great changes is attested by various remains which have been disinterred at different periods. Thirteen feet under low-water mark in spring-tides, and twenty-eight feet below the general surface of the Inches, were discovered two human skulls, a large piece of flint, and great quantities of shells and other marine deposits; and in excavating the canal, at a considerable distance from the shore, anchors and other articles of shipwreck were found deeply imbedded in the earth.
