Perspective (graphical) on the horizon line. All lines parallel with the viewer's line of sight recede to the horizon towards this vanishing point. This is the standard "receding railroad tracks" phenomenon. A two-point drawing would have lines parallel to two different angles. Any number of vanishing points are possible in a drawing, one for each set of parallel lines that are at an angle relative to the plane of the drawing. Perspectives consisting of many parallel lines are observed most often when drawing architecture (architecture frequently uses lines parallel to the x, y, and z axes). Because it is rare to have
The Parallel was sent out in. Gaines is summoned to examine the capsule, but when he approaches it he is gradually returned to the point at which he left his own universe. He lands his craft safely and reports what happened to his superiors. They are prepared to write it off as a nightmare, but controllers on the ground subsequently receive another transmission—from "Colonel" Robert Gaines.

The Major returns home and happily confirms that his daughter now recognizes him and the white picket fence is absent. The Parallel
