Quotation from: The Gods of Mars

Written by: Edgar Rice Burroughs

Xodar sat, with bowed head, upon a low stone bench near the centre
of the room in which we were. He had not spoken since Issus had
degraded him.

The building was roofless, the walls rising to a height of about
thirty feet. Half-way up were a couple of small, heavily barred
windows. The prison was divided into several rooms by partitions
twenty feet high. There was no one in the room which we occupied,
but two doors which led to other rooms were opened. I entered
one of these rooms, but found it vacant. Thus I continued through
several of the chambers until in the last one I found a young red
Martian boy sleeping upon the stone bench which constituted the
only furniture of any of the prison cells.
