Since I just read
Hair IV, and
Beards V, in
The Nature of Middle-Earth, I thought I might as well add the following. At one point,
Tolkien notes (Beards V):
"When I came to think of it, in my own imagination, beards were not found among Hobbits (as stated in text); nor among the Eldar (not stated). All male Dwarves had them. The wizards had them, though Radagast (not stated) had only short, curling, light brown hair on his chin. ( . . .)"
Okay. Why note "male" Dwarves?
Incidentally, "male Dwarves" looks italicized as typed in NOME, although the general description of the text describes that it is written in a slightly hasty hand. If my eyes do not indeed deceive me with respect to the italicization here, perhaps Tolkien did something to warrant this.
Anyway, Tolkien has clearly forgotten about
Cirdan having a beard, as well as "unpublished" text about
Elves not normally having beards until their third cycle of life. Also published by JRRT himself, the detail that the
Harfoots were
"beardless and bootless" and [later in the text] that the Hobbits of the East-farthing wore dwarf-boots in muddy weather, and that many grew
"down" on their chins . . . leading to the next sentence:
"No Harfoot or Fallohide had any trace of a beard"
The Hobbits with down and dwarf-boots being well known to be Stoors in a large part of their blood.
So, whatever Tolkien meant by
male Dwarves (arguably at least suggesting not female Dwarves), in this late text he seems to have forgotten some of what he published -- at least certainly with respect to Cirdan, if one wanted to quibble with "down" or "trace of a beard" -- and for myself, I would hold him to what was said in Appendix A . . .
. . . about the
"appearance" of Dwarf-women
