The Lithics section of the Prehistoric Group recently reassessed the Grinling-Collins collection of lithic tools held in GuildfordMuseum. Little is known about Charles Grinling (1860-1947) (below) who moved to ‘Merriedown’, Peaslake at the end of WWI, except that he is said to have excavated at Holmbury Hill (pers. Comm.: K Winser), although there does not appear to be any record of this activity. In due course he met and encouraged Patrick Collins in his interest in lithics. Collins (c1921-1991) lived at Weyside, Wonham Way, Peaslake, and joined the Surrey Archaeological Society in 1935, eventually becoming a well known and respected archaeologist in Northern Ireland. He moved from ReadingMuseum to join the newly established Archaeological Survey of Northern Ireland in 1950, and lectured at Queen’s University Belfast. Collins was primarily responsible for prehistoric sites and carried out a number of pioneering excavations on megaliths. He was interested in ancient technology and an international authority on the production methods of flint tools. His memory was honoured in 2003 when the public archive facility, Waterman House, in Belfast was opened with the naming of the research room as ‘The Pat Collins Reading Room’.
