_The Broad Arrow_ (Vol. iv., p. 315.).--I forget where it is, but
remember something about a place held by the tenure of presenting the
king with
"---- a Broad-Arrow,
When he comes to hunt upon Yarrow."
I would however suggest, that the use of an arrow-head as a government
mark may have a Celtic origin; and that the so-called arrow may be the
[Arrow symbol] or _a_, the broad _a_ of the Druids. This letter was
typical of superiority either in rank and authority, intellect or
holiness; and I believe stood also for king or prince.
