A friend writes to me that he thinks that the accounts of strange noises
in the desert would find a remarkable corroboration in the narratives of
travellers through the central desert of Australia. They conjecture that
they are caused by the sudden falling of cliffs of sand as the temperature
changes at night time. - H. C.]
Hiuen Tsang, in his passage of the Desert, both outward and homeward,
speaks of visual illusions; such as visions of troops marching and halting
with gleaming arms and waving banners, constantly shifting, vanishing, and
reappearing, "imagery created by demons." A voice behind him calls, "Fear
not! fear not!" Troubled by these fantasies on one occasion, he prays to
Kwan-yin (a Buddhist divinity); still he could not entirely get rid of
them; but as soon as he had pronounced a few words from the Prajna (a
holy book), they vanished in the twinkling of an eye.
These Goblins are not peculiar to the Gobi, though that appears to be
their most favoured haunt. The awe of the vast and solitary Desert raises
them in all similar localities. Pliny speaks of the phantoms that appear
and vanish in the deserts of Africa; Aethicus, the early Christian
cosmographer, speaks, though incredulous, of the stories that were told of
the voices of singers and revellers in the desert; Mas'udi tells of the
Ghuls, which in the deserts appear to travellers by night and in lonely
hours; the traveller, taking them for comrades, follows and is led astray.
But the wise revile them and the Ghuls vanish.
