normally is". He warned that, the Royal Commissions' completion of their inventories "cannot be expected before much of the matter of their inquiry has been either damaged or destroyed". Antiquities had been shown on OS maps from the late eighteenth century (at least two of the iconic features of these maps were introduced first in Wales: Gothic script for antiquities in 1812 and Egyptian typeface for Roman remains in 1816). Until the end of the Great War the identification and interpretation of antiquities had taken place in consultation with local experts and antiquaries, but in 1920 the Survey had appointed its first archaeological officer, O. G. S. Crawford, who built up a small but expert group, including W. F. Grimes, who later became chairman of the Welsh Commission. Throughout the 1950s and 1960s the OS archaeology branch amassed a considerable body of material on antiquities, which went far beyond what was required for mapping. The sites index included a short description and interpretation of each site, with bibliographical references and field observations. These were usually accompanied by a measured plan, normally at the appropriate basic mapping scale but sometimes supplemented with enlarged surveys and cross-sections to aid interpretation and help in draughting the published map. In 1983 the Survey's archaeological division was transferred to the three Royal Commissions along with its invaluable sites index and responsibility for surveying, interpreting and maintaining a record of archaeological sites depicted on OS maps. In Wales since then the Royal Commission itself has continued to provide mapping information to the Ordnance Survey for basic scales and for derived mapping such as the popular 1/50,000 scale Landranger series. The supply of this information is an invaluable product of the Royal Commission's archaeological survey projects, ensuring that every user of Ordnance Survey maps can appreciate the historic sites depicted. The consultants in 1988 estimated that only 11 per cent of the Commission's resources were allocated to Wales's National Monuments Record. They accordingly recommended an adjustment of the balance with the Commission's publications programme: increased priority should be given to the National Monuments Record "as the destination of... survey data" for Wales, and computer-based technologies should be developed for "the storage, retrieval and dissemination of data". Along with improved management structures and an emphasis on staff training to ensure the future capacity of the Commission, here was a clear remit for the new chairman, Professor J. B.
