The Geographical Journal for April contains an interesting paper by
Mr. 0. G. S. Crawford on " Archaeology and the Ordnance Survey." Mr. Crawford was recently appointed Archaeology Officer to the Survey, and he explains in his paper the methods which he has adopted, with the collaboration of learned societies and local specialists, for making the Ordnance maps more complete and accurate as records of surviving monuments up to the year 1688. Special attention is being given at the moment to the revision of the maps of Hertford- shire, Wiltshire, and Forfarshire. In the course of time, it is hoped, the Ordnance Survey maps will include a precise representation of all stone circles, barrows, castles, abbeys and other ancient buildings. Mr. Crawford's good work deserves to be better known, for all local antiquaries can help him in details.
