MESUR Y DORTH (MEASURE OF THE LOAF).
Between St. David’s and Fishguard is an object not unlike a milestone, upon which is rudely traced a cross within a circle: the irregular disc being about a foot in diameter. This is known as “Mesur y Dorth,” (Measure of the Loaf); and the tradition is, that St. David caused these figures to be made in order to regulate the size of the loaf of bread in times of scarcity.
