REMINISCENCES BY PROF. H. C. CAMERON. 175 



Philadelphia, met him in the college campus in Princeton. He had 

 not yet reached his home, and standing with his carpet-bag in his 

 hand, he gave the writer an account of the interview, and the rea- 

 sons which induced him to decline a position so well suited to his 

 tastes, his wishes, his attainments. He said it would not be honor-

 desired him to occupy, and where he could accomplish much for 

 science if not for himself; but especially because, if he accepted the 

 chair in Philadelphia, to which a larger salary was attached than he

 first volume of the Smithsonian Contributions, if the entire paper 

 was not accepted.* 



How faithfully the Secretary discharged all his duties is well 

 known. Amid all the corruption of public life at Washington, 

 there was never a spot upon the fair fame of Joseph Henry ; not 

 a breath ever tarnished his reputation. In addition to his duties as 

 Secretary of the Smithsonian Institution, as President of the 

 Light-house Board, he annually inspected the light-houses, and 

 devoted a considerable portion of his vacations for sixteen years to 

 experiments on light and sound for the benefit of the General 

 Government. His only compensation was his expenses. In the 

 desk in the small room that had been fitted up for him near the

 the extended Memoir on "The Ancient Monuments of the Mississippi Valley," 

 by Messrs. SQTJIEK and DAVIS; which work occupied the entire first volume of 

 the Smithsonian Contributions.]
