BORTHWICK TOWER.

The tower stands upon a tongue of rocky land, protected by deep, rugged, and wooded ravines to the south, east, and north. Down two of these flow the heads of the Middleton burn, and, below the castle, unite, to fall into the Gore water, which, gathering its springs from the adjacent Lammermuirs, flows, parallel to the railway, down a pretty pastoral valley by Gore Bridge, to the South Esk. The tower, placed over the juncture of the three streams, is a very marked object from the railway, contesting the attention of travellers with Crichton Castle, in an opposite direction, but in sight, for a few seconds, at the same time.

The platform, covered by the base-court, is an irregular figure, governed by the ground, rounded to the east, and presenting right angles to the north and south-west. Its dimensions are about 80 yards east and west, by 35 yards north and south. There is a large drum-tower at the south-west angle, and another, with a square rear, in the centre of the south front, and there are traces as of a third capping the south-east angle. These towers are 18 feet diameter, have a basement, a first and second floor, and are about 23 feet high above the court, and 35 feet to the field. In the west front, close to the angle-tower, is a gateway; an opening in a very thick low curtain, round-headed, and probably of the date of the tower. It had a drawbridge and portcullis, and may have had a low upper story. Above the door, outside, is a flat entablature, with mouldings in the Renaissance style, and the adjacent bastion and curtain are pierced with long loops, placed horizontally, evidently intended for musquetoons, and therefore insertions. They are similar to those in the north-east bastion of Berwick town wall. The southern bastion has the original vertical loops for bows and arrows. The west is the weak side, for which nature has done nothing. The curtain accordingly is on that side thickened to 12 feet or 15 feet, and there may have been a ditch, now filled up.

The court was divided by a cross wall, north and south, of no great strength, and the tower stood in the western half, from six to eight yards from the three outer walls. The northern curtain is an irregular heap of ruins; upon it, opposite to the tower door, there seems to have been a mass of masonry ascended probably by steps, and serving as an abutment to the stone arch by which the main or first-floor entrance was reached.

The Tower is rectangular, 74 feet north and south by 69 feet east and west, and from 90 feet to 110 feet high, the latter height being to the ridge of the gables. In the west front is a recess, also rectangular, 14 feet broad and 24 feet deep, so that the building in plan resembles the Greek capital Π, and may conveniently be divided into a body and wings. The recess is not quite in the centre, the north wing being 31 feet and the south 29 feet broad. Also, the latter is rather the shorter, so that the north front measures 69 feet, and the south front 68 feet. The arrangement of the chambers is very simple, all being rectangular and parallel to the sides, but the mode of reaching them by staircases is very complex. The walls are of immense thickness, the north or entrance side being 14 feet, and the other from 10 feet to 11 feet. Those of the recess, being protected, are rather less, and in parts only 6 feet. It is remarkable that these thicknesses are continued with little or no reduction, to the top. The style is simple and severe, and although the material is cut stone, of remarkably fine workmanship both inside and outside the structure, there is scarcely any ornamentation. Over the outer door, in a shallow ogee niche, is a saint or bishop in low relief, and within is a handsome canopied niche for a statue and a sort of seat of state or sedile for the lord. The fireplaces also are good, and the two larger ones of magnificent character and dimensions. These ornaments belong to the Decorated style of architecture, and correspond with the known date of the building, the first half of the fifteenth century. The walls rise from a plain plinth, and are terminated by strong corbels, 2 feet apart, and about 2 feet deep, between each of which was a “meurtrière,” and outside it a low parapet, now removed. As usual with Scottish towers, at each angle was a three-quarter low bartisan resting on the corbels, and probably rising no higher than the parapet. Also, the three high-pitched roofs of the body and wings rise above and within the walls, being set back from 6 feet to 8 feet. The chimneys, where they remain, are tall and handsome, and the three well-staircases opening on the roof were housed in cylindrical turrets with conical roofs, of which one remains, wanting only its finial.

The basement is on the ground level, which is about 5 feet below the exterior ward. Above it is a first floor, which in the body is occupied by the great hall, above which is a second floor containing the chapel and upper hall. Above this is a third floor. The divisions of the wings are less lofty. The north contains six floors, the south five. There are five well-staircases in different parts of the building. Two ascend from the ground level to the first floor and there stop. Two others commence at that floor and ascend to the roof, supplying the intermediate floors, and another commences half-way up the height of the hall, threads two walls as a gallery, and finally rises as a well-stair to the roof. There was thus a ready access from the first and upper floors to the battlements in case of danger.

Basement.—In the body are three chambers placed crossways, east and west, side by side, all 23 feet long, the central 14 feet wide, the others 15 feet. The vault springs 14 feet from the floor, and in each, at the east end, is a large arched recess, high up, narrowing to a loop. At the springing line of each vault is a row of strong corbels, evidently to support a floor, a sort of windowless entresol. These lower chambers communicate by doors, and in the south wall of the most southern is a recess or cupboard. The outer doorway, 6 feet wide, at the level of the ground outside, is in the north wall, and is closed by a stout door, within which the passage descends eight steps. In the same wall is a well-stair, which ascends from the basement to the first floor, and there stops. In this, half-way up, is a door into the entresol over the northern chamber, from which level the stair is continued to the first floor. The entresols over the other two chambers were reached by ladders. The whole range clearly was intended for stores, in case of a siege.

From the north and south chambers doors open into the basements of the two wings, also vaulted. The north, the prison, is 18 feet by 12 feet, with a high and narrow loop to the west. In its upper part is also a small door, from the adjacent entresol, which may have opened upon a similar floor above the prison, or may have been an opening to look down into it.

In the left wing is a vault 20 feet long by 12 feet 6 inches broad, and only 8 feet high. This was reached from the adjacent chamber in the body, and contained the well. From this chamber, opening in the south wall, is a well-stair, which rises 10 feet to an entresol, and thence proceeds to the first floor. This entresol, also vaulted, was 18 feet by 12 feet. There is a fireplace and cupboard in the north wall, and in the south a small loop, a mural garderobe, and the door of entrance. From it a rise of 14 feet leads to the first floor, which is thus 24 feet above the basement.
