Paifa area that Hasan took refuge when it petered, out,
skipping tron there into definitely Yeaeni territory*
And it is now in the same region that 'Abdul Wahhab al
Idrisi has joined in or created a fresh revolt, which
may be only a stirring up of the embers of the old.
We have been tempted to think that the area now
in question was that claimed by the Imam under the name
ol Hamazan or Hamdan, when the Saudi delegation were at
San'a. This would make his claim intelligible, i.e., he
would have been asking for the Tihama, the area now in
question and the yahtan country, that of the tribes whose
overlord was Ibn Dhulaym; the whole frontier area
in fact as far as Najran, which he regarded as his own in
any case. This has some value as a working theory but we
must coni ess that all attempts to associate the very
common name Hamdan with the particular area have broken down*
One more point:- The Minister, when at home, told
Johnstone that he though 'Asir Tihama was the approved
Saudi name for the province formed out of the former
Idrisi territory* He now thinks that the more approved
form is Tihamat 'Asir. You may find us using both, as
Asir Tihama is more euphonious and a nicer contrast to
Asir Surat, but the meaning is clear whatever order is
used, i.e., the conjunction of Tihama and 'Asir indicates
the littoral and that part of the highlands of which the
Idrisi was still the ruler in 1926.
Yours ever.
CHANCERY.
