From the point of view of the _Pawn_, the surface of the Chess-board
takes on the topographical aspect of a country which as it is entered,
constantly becomes wilder and more rugged.
The march of the Pawn always is along a valley situated between
impracticable natural barriers, and the possible movements of the Pawn
always decrease as the distance traveled increases.
Unhindered by either kindred or hostile corps, the Pawn may reach any
point of junction in the kindred Logistic Horizon, which is contained
within its altitude, in a minimum of five and in a maximum of six moves.
It may march only in one direction, except in capturing, when it may
acquire the option of acting in three directions.
The weakness of the topographical horizon of the Pawn originates in its
inability to command the adjacent country. Therefore, it is exposed to
unopposed attack along verticals and horizontals by the hostile King,
Queen and Rooks; along diagonals by the adverse King, Queen and Bishops,
and along obliques by the adverse Knights.
