core = caw.
door = daw*.
floor = flaw*.
hoar* = haw.
lore* = law.
more = maw*.
oar, ore = awe*.
pore = paw.
roar = raw.
soar, sore = saw, saw.
tore = taw.
yore* = yaw.

Of these 12 words, 6 exhibit stages or symptoms of obsolescence. I
should think it extremely unlikely that _yore_ has been in any way
incommoded by _yaw_; and _flaw_, which is now more or less cornered
to one of its various meanings, was probably affected more by its own
ambiguities than by _floor_; but others seem to be probable examples:
_shaw_ and _lore_, and I think _maw_, are truly obsoletes, while
_hoar_ and _daw_ are heard only in combination. _Awe_ is heard only in
_awful_, and has there lost its significance. I should guess that this
accident has strengthened its severity in literature, where it asserts
its aloofness sometimes with a full spelling [_aweful_] as in speech
two pronunciations are recognized, _awful_ and _awf'l_.

Now how do these words appear in Jones' dictionary? If there is to be
any difference between the _aw_ and _ore_ sounds either the _R_ must
be trilled as it still is in the north, or some vestige of it must
be indicated, and such indication would be a lengthening of the _o_
(=_aw_) sound by the vestigial voicing of the lost trill, such as is
