Hare-stone = Hour-stone.
Boundary stone in the parish of Sancred (Cornwall), with a heap of stones round it. It is thought that these stones were set up for a similar purpose as the column set up by Laban (Genesis xxxi. 51, 52). Behold this heap, and behold this pillar, said Laban to Jacob, which I have cast betwixt me and thee. This heap be witness, and this pillar be witness, that I will not pass over this heap to thee, and that thou shalt not pass over this heap unto me, for harm. (Anglo-Saxon, hora, or horu stan.) (See HAROLDS STONES.)
