Locations of certain places

OTOH, CT naturally never regarded the 1954 Map as precisely canonical, since his father didn't draw it: it was a copy of his father's, which would be the Vulgate, and presumptively more 'correct' than CT's rendition.

I can even imagine JRRT observing "You've missed out Himling- but it's not that important." Or CT at the time, having already laboriously done the contour-lines around the coast of the mainland, realizing too late that he'd drawn over the island's location. What I can't imagine is JRRT telling him to leave it out- in that case one would expect it to have been erased or crossed off on Tolkien's original: and in the face of such an explicit instruction, CT wouldn't have put it back in the 1980 Map.

Whatever happened, Christopher Tolkien explains...

'... and I have shown the little island of Himling off the far north-western coast, which appears on one of my father's sketch-maps and on my own first draft. Himling was the earlier form of Himring (...) and though the fact is nowhere referred to it is clear that Himring's top rose above the waters that covered drowned Beleriand. Some way to the west of it was a larger island named Tol Fuin, which must be the highest part of Taur-nu-Fuin.' Christopher Tolkien, Unfinished Tales

Good point.

IIRC, all the new elements in the Baynes map were place-names, chiefly rivers (and I suspect on Tolkien's mind at the time, 'The Rivers and Beacon-hills of Gondor' dating from about then). In other words, he gave PB some names to add to previously nameless features, but not new features.
