Summary. An opportunity arose to carry out a small-scale site investigation to the north-east of Palmer's Farm, Birch. The investigation consisted of a limited geophysical scan followed by trial trenching. The geophysical survey produced several point anomalies, but no distinct outlines of buried features. The areas where anomalies occurred were investigated in the course of the trenching. A fairly close correspondence was found between the incidence of surface finds and the underlying presence of convincingly early archaeological features.
