Despite Finberg’s identification of this double-page sketch (continuing on folio 54; D17599) as Port Edgar (with which Gerald Finley and David Wallace-Hadrill have agreed),1 this is identifiable by a number of landmarks as Leith and Granton Harbours. At the left of the page Leith is recognisable from the Martello tower, the now removed old West Pier, the cylindrical Signal House and just to its left the Leith Glass Works. The harbour continues to the right where on folio 54 it merges with Granton harbour. At the very left of the page is the distant outline of North Berwick Law.
