Botany and Plant Ecology Studies

Following the discovery of well-preserved fossil plants at Weak Law, North Berwick (Gordon, 1935, p. 280), a search of all the volcanic ashes in the neighbourhood was undertaken and special attention was given to those localities from which plant-remains had been recorded in the past. Isolated specimens had been from time to time discovered, but were usually of an unsatisfactory character—mostly fragments of charred wood such as frequently occur in volcanic ashes. More satisfactory specimens were found by Mr James Whitecross of North Berwick, and were recorded by the late Mr T. Cuthbert Day (Day, 1928, p. 48), from a thin bed of limestone in the ashes of Gin Head, Tantallon, and elsewhere in the vicinity.
