travellers' tales that other men tell. Childe Roland is not the only
traveller who has challenged the Dark Tower.

In the Middle Ages Nicolai Leontievitch Markovitch would have been
called, I suppose, a Magician--a very half-hearted and unsatisfactory
one he would always have been--and he would have been most certainly
burnt at the stake before he had accomplished any magic worthy of the
name. His inventions, so far as I saw anything of them, were innocent
and simple enough. It was the man himself rather than his inventions
that arrested the attention. About the time of Bohun's arrival upon the
scene it was a new kind of ink that he had discovered, and for many
weeks the Markovitch flat dripped ink from every pore. He had no
laboratory, no scientific materials, nor, I think, any profound
knowledge. The room where he worked was a small box-like place off the
living-room, a cheerless enough abode with a little high barred window
in it as in a prison-cell, cardboard-boxes piled high with feminine
garments, a sewing-machine, old dusty books, and a broken-down
perambulator occupying most of the space. I never could understand why
the perambulator was there, as the Markovitches had no children. Nicolai
Leontievitch sat at a table under the little window, and his favourite
position was to sit with the chair perched on one leg and so, rocking in
this insecure position, he brooded over his bottles and glasses and
trays. This room was so dark even in the middle of the day that he was
often compelled to use a lamp. There he hovered, with his ragged beard,
his ink-stained fingers and his red-rimmed eyes, making strange noises
to himself and envolving from his materials continual little explosions
that caused him infinite satisfaction. He did not mind interruptions,
nor did he ever complain of the noise in the other room, terrific though
it often was. He would be absorbed, in a trance, lost in another world,
and surely amiable and harmless enough. And yet not entirely amiable.
