Yet another of the important public works of the colony, upon which the labour of Indian convicts was employed some five years earlier, was at the construction of the lighthouse on "Pedro Branca," called the "Horsburgh," after the celebrated hydrographer of that name. The design was by Thompson, and the selection of the site by Sir Edward Belcher, R.N., and most of the detail work was under the direct supervision of Mr. J. Bennett, a civil and mechanical engineer, who afterwards, as we have said, played a prominent part in the direction and control of the labour and industrial training of the Indian convicts in the Singapore jail. He had, as an assistant, Mr. Magaelhaens of the Convict Department, and both the officers and the convicts lived on board of a "Tonkong," or a large boat, which was anchored close to the rock. The convicts were chiefly employed in the capacity of blasters and dressers of stone. The foundation stone was laid with masonic honours by the Worshipful Master Brother M. F. Davidson, on the 24th May, 1850, in the presence of the Governor, Colonel Butterworth, and a large party from Singapore; and the work was completed and the lamps lighted on the 27th September, 1851. The _Free Press_ spoke of it as an edifice of which Singapore might well be proud. "The granite blocks which form the walls were quarried and shaped at Pulo Ubin, the timber used in the building was the growth of our island, the brass rails of the staircases were moulded and turned in this settlement, and last, not least, the architect and engineer acquired the skill and experience which enabled him to erect so rapidly the chaste and stately building during a long and useful career as Government Surveyor at Singapore." Both the quarrying of the stone at Pulo Ubin, and the felling of the timber required in the erection of this lighthouse, were by the work of Indian convicts. In 1845 the foundation stone of a second lighthouse was laid on a reef near a small island at the eastern entrance to the Straits of Malacca called "The Coney." It was also laid with masonic honours by the Worshipful Master and Brethren of the Lodge Zetland in the East, No. 748, in the presence of the Governor, Colonel Butterworth, and many of the British and foreign residents at Singapore. This lighthouse was named after the eminent founder of the settlement, Sir T. Stamford Raffles, and was completed in 1856. It was built by free labour, but many convicts were employed, as at the "Horsburgh," as stone cutters, blasters, and as labourers, under the charge of an officer of the Convict Department.
