HENRI LOUIS FRANCOIS MARINDIN. 225 



On March 24, 1897, he was appointed by President Mc- 

 Kinley to represent the Coast and Geodetic Survey on the Mis- 

 sissippi River Commission, and after that date devoted much 

 time and attention to the duties thus imposed upon him, but 

 continued his regular work on the Survey whenever it was pos- 

 sible to do so. His particular ability was recognized by numer- 

 ous special assignments to duty in connection with harbor boards 

 to establish harbor lines, and in the establishment of speed trial 

 courses for vessels of the navy, and is shown in several scientific 

 discussions of various physical problems relating to hydrog- 

 raphy which have appeared from time to time as appendices 

 to the annual report of the superintendent. 



His death took place March 24, 1904.
