     It seems that fate likes to play strange jokes on those who are famous.The manner in which fate

saved Clive of India for his mission in history is a matter of record.Downhearted, ill, and depressed,

Clive, then a young clerk, placed a revolver(左轮枪手) to his head and snapped the trigger time after

time.It refused to fire and he realised that suicide was not to be his lot.A subordinate (下属) took the

same pistol from Clive's hand and fired it six times in succession(连续).

     A somewhat different but disturbing fate laid in store for Robert Todd Lincoln, the eldest son of the

Civil War President.Young Lincoln had received orders to report to Washington.In White House he

was told that his parents had gone to Fords Theatre and they had requested that he join them there.

Robert Todd Lincoln went to the theatre and, just as he entered the building, he was stretched back

by a crowd of excited people, among whom were the stretcher bearerscarrying the dying President.

     During the administration of President Garfield, Robert Todd Lincoln became Secretary of War.

He was a close personal friend of President Garfield and, when the President prepared to leave for a

visit to the seashore at Elberton, New Jersey, Secretary Lincoln accepted an invitation to go along.As

Secretary Lincoln reached the railway station, he encountered the stretcher bearers carrying out the

fatally wounded President Garfield, victim of an assassin's(刺客) bullet.

     Twenty years later, as Robert Todd Lincoln entered the Temple of Music in Buffalo to greet

President McKinley, the President was carried past him by stretcher bearers.Garfield, Lincoln, and

McKinley were the presidents to be assassinated (暗杀), and Robert Todd Lincoln was the only man

who was on the scene immediately after all the shootings.
