the Governor's understanding of the situation, he did not communicate it to the Sultan and Temenggung. It is unclear whether the correspondence was limited to Peak Rock or extended to other potential sites for the lighthouse such as Pedra Branca, and whether the sovereignty of Johor over any place chosen for the lighthouse was ceded to the British Government or only a permission to build, maintain and operate a lighthouse was granted. On 22 August 1845, Governor Butterworth wrote again to the Government of India, indicating he trusted that construction of the lighthouse on Peak Rock would begin soon "as a light in that quarters is becoming daily of more paramount importance". Between 1824 and 1851, at least 16 sizeable vessels were wrecked in the vicinity of Pedra Branca and Point Romania (on the Johor coast). However, in April 1846, the Lords of the Admiralty in London informed the Court of Directors of the East India Company they were inclined to think that Pedra Branca was the best point for the lighthouse. John Thomson and Captain S. Congalton, commander of the East India Company's steamer called the Hooghly, carried out surveys in May and August. In a report dated 25 August, they said they were "decidedly of opinion that Pedra Branca is the only proper position for a Light to be placed ... for the safety of Shipping whether entering or departing for the Straits of Singapore ..." The following day, Governor Butterworth wrote to the Government of India stating that the Government "will at once perceive that Pedra Branca is the only true position" for the lighthouse. On 30 October 1846, the President in Council in India approved Pedra Branca as the site for the lighthouse. The East India Company gave its approval on 24 February 1847, and on 10 May of that year the Government of India asked Governor Butterworth to take measures for the construction of the lighthouse. There is no evidence that the authorities in Singapore thought it necessary or desirable to inform the Johor authorities of the decision about the siting of the lighthouse or to seek any consent for its erection. Although the private subscribers wishing to commemorate Horsburgh had raised a sum which, with compound interest, came up to more than 7,400 Spanish dollars when it was paid over to the Singapore authorities, there was still a shortfall of funds for the building
