One of Agassiz's great pleasures in the 

 summer of 1847 consisted in excursions on 

 board the Coast Survey steamer Bibb, then 

 employed in the survey of the harbor and 

 bay of Boston, under command of Captain 

 (afterward Admiral) Charles Henry Davis. 

 Under no more kindly auspices could Agas- 

 siz's relations with this department of govern- 

 ment work have been begun. "My cabin," 

 writes Captain Davis, after their first trip to- 

 gether, " seems lonely without you."
