     An anemometer constructed by the Soil Mechanics Laboratory of the Western Region, British Railways, has been installed at Dawlish Warren, near Exeter, to obtain a record of the velocity (speed and direction) of the wind. This information is used for the study of the effects of wind erosion on the sand dunes which protect the railway from the sea at that point.
