Tjaard Kruger was succeeded in office by a most clever and interesting celebrity, Dr. Leyds, Secretary of State, who was the only man who made the department a success. He showed the unfailing tact of the born diplomat. He was a great reader of character and formed a pretty accurate estimate of a person in a surprisingly short time. He conducted his affairs so delicately and diplomatically that he won universal esteem and the staunchest and most loyal adherents. He would hand over disagreeable work to a subordinate so gracefully that it gave the impression that he was relegating the work, not because it irked him, but because he had found a man more capable than himself--the man whom he had long sought.
Dr. Leyds' letters of instructions to his agents were clear, precise, and exacting, and provided for every possible contingency; yet had they fallen into the hands of the unauthorised they would have conveyed little. These letters bespoke the diplomat. They would have come safely out of an investigation by a committee of suspicious spy-hunters.
When he required to "draw" any person he would instruct his agents to ascertain carefully that person's tastes, habits, prejudices, and amusements. These he would study to the minutest trifle, and by skilful play upon a weakness, or by the evidence of a similar taste, he would successfully penetrate to the most exclusive and jealously guarded sanctum sanctorum.
Mr. Hamil Grant is an author who may be congratulated upon his carefully-compiled work, entitled, "Spies and Secret Service," which contains the history of espionage from earliest times to the present day. He shows how the practice was used by Joshua, David, Absalom, and the mighty warriors whose deeds of valour are recorded in the Old Testament. He quotes Alexander Mithridates, the King of Pontus, who made himself the master of twenty-five languages and spent seven years wandering through countries he subsequently fought and vanquished. He traces developments from Alexander the Great, who lived 300 years before Christ and was the first known to start secret post censorship; from Hannibal, who could never have crossed from Andalusia over the Pyrenees and the Alps into the plains of Piedmont to fight the battle of Trebia (218 B.C.) without the assistance he received from the intelligence scouts who preceded him. He points out how Cæsar and the great generals who conquered Europe invariably used scouts and intelligence agents. He quotes Napoleon's admission of indebtedness to Polyænus for original strategic ideas of espionage; whilst he has much to say in proving that no war of either ancient or modern times was successful without it.
