His strong command of the Hindustani language meant he could easily converse with
Indian convicts which was particularly useful since he had only one assistant, a European warden, the petty officers being selected among the convicts themselves. McNair employed the
Indian convicts in the construction of roads all over
Singapore and buildings like the
St Andrew's Cathedral, Singapore and Government House (known as
The Istana). In 1867, he accompanied Sir
Harry Ord the new governor of
Straits Settlements back to
Singapore, when control of the
Straits Settlements was transferred from the
India Office to the
Colonial Office in
London. He was appointed
Colonial Engineer and through his efforts, the building of the water works which had been plagued with failures, was successfully completed. In 1874, though not a commissioner himself, he was involved with the Commission for the Pacification of
Larut in
Perak comprising then Captain Samuel Dunlop, F. A. Swettenham,
Chung Keng Quee and Chin Seng Yam. Sir Andrew Clarke started the title "Empress of India," and asked Major McNair to translate this. Of the several versions he provided, "Kaisar-i-Hind" was selected and officially used for the first time in Sir Andrew's proclamation, which was at once sent home to the Secretary of State for the Colonies, the Earl of Carnavon. In 1875, Following the murder of J. W. W. Birch and the Perak War it started, he was appointed
Chief Commissioner inquiring into the complicity of the Chiefs of Perak, 1875-1876. In 1882, he was appointed
Acting Resident Councillor to the Governor of
Penang. McNair Street in
George Town is named after him. He resigned his position in 1884 on medical grounds after a distinguished career in the
Straits Settlements spanning many different positions (he had acted as
Colonial Secretary in
Singapore at one time) and locations (he was once in charge of artillery in
Labuan). His several missions to
Siam (now
Thailand) gained him familiarity with its
King of Thailand and was conferred with the
Order of the White Elephant by his majesty King of Siam. On 24 May 1879, he was appointed a Companion of the
Order of St Michael and St George. ==See also==
