These, however, are by no means typical of the whole of Britain and research is needed into soils found extensively in Scotland and other parts of Britain which differ greatly in their origin, nature and properties from those which have hitherto been the chief subjects to

... ich British investigators have devoted attention. The various agricultural colleges are taking up the study of the soils of their respective •districts, and when the Farm of Craibstone was acquired as an Experiment Station by the North of Scotland College, a series of soil investigations was immediately commenced. Craibstone is situated about six miles north-west of Aberdeen and is a farm typical of much of the agricultural land of the district and of the North of Scotland generally. The soil is a boulder clay overlying granite and varies much in depth; the subsoil also varies much in depth and texture, passing within a short distance from sand and gravel to clay.
