This is a scarce large format 1936 geological survey of Hong Kong issued by the British Ordnance Survey and the War Office. The map covers all of Hong Kong, as well as Lan Tao, Lamma, the New Territories, and Kowloon. Color coding throughout identifies different soil and bedrock types. They city of Hong Kong, today's Central, is identified as Victoria.

The map is a composite complied from existing British intelligence maps, Admiralty Office charts, the Tate Survey of 1899-1900, and the New Territory Survey of 1902-1903. It was updated in the 1920s and 1930s by S. J Schofield, M. Y Williams, and Reginald Walter Brock, to whom this addition of the map is primarily attributed. We have been able to identify five other examples of this map, in various editions, located at the University of Illinois, the University of Hong Kong, the University of Minnesota, the University of Oxford, and at the National Library of Australia.


Reginald Walter Brock (1874 - 1935) was a Canadian geological and cartographer active in Canada and Hong Kong in the late 19th and early 20th centuries. Brock was born in Perth, Ontario. He enrolled in the Queens University of Toronto in 1893 attaining a M. A. in Geology. He continued his studies in Heidelberg. His first geological survey work the 1897 Dawson Survey of British Columbia. In 1907, he was appointed Director of the Geological Survey of Canada, a position he held until 1914. In 1914, he took a position as Dean of Applied Science at the newly created University of British Columbia. At the outbreak of World War I, he joined the Seaforth Highlanders with the rank of Major and served in Palestine under General Allenby. From 1922 – 1927 his talents were harnessed by the British Ordnance Survey to update the geological survey of Hong Kong. After completing the Hong Kong Survey, he returned to the Queens University of Toronto where he served as Dean until he death in tragic 1935 plane crash. Learn More...

The British Ordnance Survey (1791 - present) is the national mapping agency of Great Britain and is one of the largest producers of maps in the world. This non-ministerial department of the government of the United Kingdom is responsible for producing maps of Great Britain and many of its overseas possessions. The history of the Ordnance Survey goes back as far as 1747, following the Jacobite rising, when King George II commissioned a comprehensive military survey of Scotland to assist further campaigns. The result, produced by Paul Sandby, John Mason and William Roy, was the Duke of Cumberland's Map, the first military quality map of the British Isles. This grew into the Principal Triangulation of Great Britain (1783-1853) under William Roy, and eventually lead to the creation of the Ordnance Survey in 1791. Today the Ordnance Survey produces a large variety of paper maps and digital mapping products. Its large scale maps, issued to the scale of 1:10000, available in sheet map form until the 1980s, are now only available digitally. All maps produced by the Ordnance Survey are in copyright for 50 years after publication. Learn More...
