Note 965 — BLACK LEAD.
William Johnston translation
In the Cumberland dialect, killow or collow, as well as wad, means black. Therefore when the manganese earth, which is found chiefly at Elton not far from Winster, and when burnt is employed as an oil-colour, but particularly for daubing over ships, is called black wad, that expression signifies as much as black black. See Pennant’s Tour in Scotland, i. p. 42. Gentleman’s Magazine, 1747, p. 583.
