One can scarce overestimate the value of modern methods of communication to the world.  So much of our development has been more or less directly dependent upon it that it is difficult to fancy our situation without the telegraph and telephone.  The diligence with which the ancients sought speedy methods for the sending of messages demonstrates the human need for them.  The solution of this great problem, though long delayed, came swiftly, once it was begun.

Even the simple facts regarding “Masters of Space” and their lives of struggle and accomplishment in sending messages between distant points form an inspiring story of great achievement.

COMMUNICATION AMONG THE ANCIENTS

It was very early in the history of the world that man began to feel the urgent need of communicating with man at a distance.  When village came into friendly contact with village, when nations began to form and expand, the necessity of sending intelligence rapidly and effectively was clearly realized.  And yet many centuries passed without the discovery of an effective system.  Those discoveries were to be reserved for the thinkers of our age.

We can understand the difficulties that beset King Agamemnon as he stood at the head of his armies before the walls of Troy.  Many were the messages he would want to send to his native kingdom in Greece during the progress of the siege.  Those at home would be eager for news of the great enterprise.  Many contingencies might arise which would make the need for aid urgent.  Certainly Queen Clytemnestra eagerly awaited word of the fall of the city.  Yet the slow progress of couriers must be depended upon.

One device the king hit upon which was such as any boy might devise to meet the simplest need.  “If I can go skating tonight,” says Johnny Jones to his chum, “I’ll put a light in my window.”  Such is the simple device which has been used to bear the simplest message for ages.  So King Agamemnon ordered beacon fires laid on the tops of Mount Ida, Mount Athos, Mount Cithaeron, and on intervening eminences.  Beside them he placed watchers who were always to have their faces toward Troy.  When Troy fell a near-by fire was kindled, and beacon after beacon sprang into flame on the route toward Greece.  Thus was the message of the fall of Troy quickly borne to the waiting queen by this preconceived arrangement.  Yet neither King Agamemnon nor his sagest counselors could devise an effective system for expediting their messages.
