"The lighthouse on the Isle of May is situate at the entrance of the Firth of Forth, in North lat. 56° 12´, and long. 2° 36´ west of London. From the lighthouse Fifeness bears by compass N. by E. 1/2 E., distant five miles; and the Staples Rocks, lying off Dunbar, S. by W. 1/2 W., distant ten miles. The light, being formerly from coal, exposed to the weather in an open grate or choffer, was discontinued on the night of the 1st of February, 1816, when a light from oil, with reflectors, known to mariners as a Stationary Light, was exhibited. The new lighthouse tower upon the Isle of May is contiguous to the side of the old one, and is elevated 240 feet above the medium level of the sea, of which the masonry forms 57 feet, and is therefore similar to the old tower in point of height. The new light is defended from the weather in a glazed light-room, and has a uniform steady appearance, resembling a star of the first magnitude, and is seen from all points of the compass, at the distance of about 7 leagues, and intermediately, according to the state of the atmosphere." In the summer of 1814, shortly after the May had been acquired by the Northern Lights Board, Sir Walter Scott accompanied the Commissioners on their visit of inspection. In the Diary which he kept during the cruise, the following entry occurs under date of the 29th of July, the day on which the lighthouse yacht sailed from Leith:--"Reached the Isle of May in the evening, went ashore, and saw the light--an old tower, and much in the form of a border-keep, with a beacon-grate on the top. It is to be abolished for an oil revolving-light, the grate-fire only being ignited upon the leeward side when the wind is very high.... The isle had once a cell or two upon it. The vestiges of the chapel are still visible. Mr. Stevenson proposed demolishing the old tower, and I recommended 'ruining' it 'à la picturesque', i.e., demolishing it partially. The island might make a delightful residence for bathers."[229] Scott's romantic suggestion was not, however, adopted. The old lighthouse tower on the Isle of May was reduced in height to about 20 feet, and by direction of the Board was converted into a guardroom for the convenience of pilots and fishermen. The square, battlemented, white building is still standing at the present day. Above the door there is a tablet with a figure of the rising sun over the date 1636. It is surmounted by a lion holding an escutcheon, on which the armorial bearings--probably those of the builder--are no longer decipherable. In the vaulted room within the tower there is an old iron grate with the initials A. C., which suit Alexander Cunningham, and are doubtless his.
