In 1813, Dr. Strachan succeeded Dr. Stuart as incumbent of the church; and in 1818 he induced the congregation to effect some alterations in the structure. From an advertisement in an early _Gazette_ of the year 1818, it will be seen that the ecclesiastical ideas in the ascendant when the enlargement of the original building was first discussed, were much more in harmony with ancient English Church usages, than those which finally prevailed when the work was really done. With whomsoever originating, the design at first was to extend the building eastward, not southward; to have placed the Belfry at the west end, not at the south; the Pulpit was to have been placed on the north side of the Church; a South Porch was to have been erected. The advertisement referred to reads as follows:--"Advertisement. Plans and Estimates for enlarging and repairing the Church will be received by the subscribers before the 20th of March, on which day a decision will be made, and the Contractor whose proposals shall be approved of, must commence the work as the season will permit. The intention is: 1st. To lengthen the Church forty feet towards the east, with a circular end; thirty of which to form part of the body of the Church, and the remaining ten an Altar, with a small vestry-room on the one side, and a Government Pew on the other. 2nd. To remove the Pulpit to the north side, and to erect two Galleries, one opposite to it, and another on the west end. 3rd. To alter the Pews to suit the situation of the Pulpit, and to paint and number the same throughout the Church. 4th. To raise a Belfry on the west end, and make a handsome entrance on the south side of the Church, and to paint the whole building on the outside. Thomas Ridout, J. B. Robinson, Churchwardens. William Allan. Feb. 18, 1818." The intentions here detailed were not carried into effect. On the north and south sides of the old building additional space was enclosed, which brought the axis of the Church and its roof into a north and south direction. An entrance was opened at the southern end, towards King Street, and over the gable in this direction was built a square tower bearing a circular bell-turret, surmounted by a small tin-covered spire. The whole edifice, as thus enlarged and improved, was painted of a light blue colour, with the exception of the frames round the windows and doors, and the casings at the angles, imitating blocks of stone, alternately long and short, which were all painted white.
