“One man crosses the path in the common direction which is suggested by the purpose he has in view, or by mere accident. If others follow in the same track, which they are likely to do after it has once been trodden, a parth is made………. Before a custom is formed, there is no juristic reason for its taking one direction rather another, though doubtless there  was some ground of expediency or religious scruple, or of accidental suggestion. A habitual course of action formed gathers strength and sanctity every year….. There can, in fact be no doubt that customary ruled existed among people long before nations or states had come into being”, observed.
