A wanly glimmering shape drew by; halted.

It was like a rigid serpent cut from a gigantic square bar of cold blue steel.
Its head was a pyramid, a tetrahedron; its length vanished in the further darkness.

The head raised itself, the blocks that formed its neck separating into open wedges like a Brobdignagian replica of those jointed, fantastic, little painted reptiles the Japanese toy-makers cut from wood.
It seemed to regard us--mockingly.

The pointed head dropped--past us streamed the body.

Upon it other pyramids clustered--like the spikes that guarded the back of the nightmare Brontosaurus.
