The So-called Catrail

Abstract

In many districts of our country, from the South of England northwards, there exist works of unknown antiquity called black-dykes, devil's-dykes, Grim's dykes, and other such names. They consist of a trench with an accompanying mound, of widely varying dimensions, and run across country with a curiously winding course, being frequently traceable for many miles. The most famous in Scotland has become known as the Catrail. The conception of a continuous line, or of a series of more or less\r\nconnected sections forming a unit, appears to be without foundation. It is argued that five separate parts can be identified and these are described in detail.
