"Kelson!" he gasped. "How on earth did you get here? Are you a
projection?"

"Don't worry me with questions," Kelson replied. "I have come to give
you instructions. A paper and ink, quick."

Hamar obeyed with alacrity.

"On you," Kelson wrote, "is conferred the property of invisibility--a
property common in Atlantis, and still possessed by the Fakirs of
Hindoostan, the natives of Easter Island and certain tribes in New
Guinea. You must reach grade three in the scale of concentration, by
concentrating, from five to six o'clock, every morning, on
amalgamating yourself with the ether. You must sit, with your head
thrown back, gazing up into space--allowing nothing to distract your
mind. Wholly and solely, your thoughts must be fixed on the ether.
This property of invisibility can only be successfully practised, when
the third grade in the scale of concentration has been reached. Carry
out these instructions, and, in a week's time, you will then be able
to experiment--to become invisible at will. But before experimenting it
will always be necessary to repeat the words 'Bakra--naka--taksomana,'
and to swallow a pill, composed of two drachms of Derhens Voskry, one
drachm of Karka Voli and one drachm of saffron. Derhens Voskry and
Karka Voli are a crimson and white species of seaweed, that grows on
the hundred-fathom level, thirty miles west-southwest of the Aran
Islands, Galway Bay. Mr. John Waley, employed by the Brazilian
Government for repairing cables, will procure these ingredients for
you. To become visible, you've only to repeat the words,
'Bakra--naka--taksomana,' backwards."

"But how about my clothes?" Hamar asked. "Will they disappear too?"

"Everything!" Kelson answered. "Hat, boots, tie and breeches. All you
have on! Good-night!" And walking out of the room, he leaped into the
air, and flew downstairs. But though Hamar listened attentively, he
could not hear him leave the building--there was no sound of any door.

When they met the following mid-day in Cockspur Street, Kelson
remembered nothing of his visits.

"All I know is," he said, "that the moment I got into bed, I fell
asleep, and suddenly found myself standing in a kind of brown desert,
talking to a tall man with most peculiar features and eyes, and a
dazzling, white skin. He informed me he had been an animal-trainer in
the State of Ballyynkan, Atlantis, and was ordered to give me
instructions as to the taming of the present day wild beast.
