Peterhead, like the neighbouring ports already noticed, has rapidly increased, within the last twenty years, in all those means which facilitate and secure the advantages of trade and commerce. Though long and deservedly resorted to as a delightful watering-place, remarkable for the salubrity of its air, and the beauty of its situation, the activity of trade was still unknown to its inhabitants. Its only harbour, a small basin dug out of the rock, was rarely enlivened by anything that could aspire to the title of shipping; for in Cromwell's time, about twenty tons of boat-freight was all that its diminutive port could lay claim to. The spirit of its inhabitants, however, with an accurate perception of the natural advantages of the Port, and aided by government in the preparation for a new era in commercial enterprise, has achieved wonders. An air of prosperity animates the whole town: the harbour is filled with goodly traders; imports and exports cover the quays: industry has received a stimulus which communicates its happy influence to everything around; and Peterhead now holds an enviable station among the Ports and Harbours of Great Britain. The point of land on which the town is built, is the most easterly of the mainland of Scotland. It forms the north-east side of a bay, and is connected with the country, on the north-west, by an isthmus eight hundred yards in breadth. On Keith-Inch, so called from the Earl Marischal, are many elegant and substantially-built houses; and on its south-side is an old Castle, erected in the sixteenth century, by George, Earl Marischal, after the model of one which he had seen in Denmark. Down to the close of the sixteenth century, Peterhead was only a small fishing-village, and the stranger who now passes through its populous streets, and busy harbours, will readily perceive how much has been accomplished in the interval.
