126 HEREDITY AND DEVELOPMENT OF NAVAL OFFICERS. 



at West Point, for over 40 years. He was of pure Irish blood. He lived for 

 a while in Norfolk, Virginia, was graduated at West Point, and earned a distin- 

 guished reputation there. He was sent to France for higher military education. 

 He had no strong bias toward arms, but was very fond of drawing and sought the 

 Military Academy as a means to this end. The following incident illustrates his 

 though tf ulness : Once he was on a board where an objectionable project was 

 offered by an influential officer. A young member of the board asked his advice 

 about opposing it, hesitating on account of the odium that such opposition would 

 bring to him. Mahan advised the young man against such action and then threw 

 the force of his great influence against the proposition and defeated it.
