WILLIAM HILLOCK CLARK. 413 



I was to start for a suniincr trip to Europe with Prof. Wm. North Rice, 

 and that if lie wanted to study j^eology I coukl never give him a better 

 chanee, if lie would come with us. 



He went home next Sunday and it was a bomb shell in this (luiet 

 methodical family, but he joined us on the trip. I think it had been 

 settled that he should continue abroad for study, for he met me in 

 Xew York with a large Saratoga trunk and a smaller trunk and I 

 persuaded him to cull out what he really needed and send most of tlie 

 material home in the bigger trtmk. 



With my careless and forgetful ways I am afraid I was a trial for him 

 with his methodical and careful habit of doing things, for his interesting 

 letters were sent by his mother down to my home for the amusement 

 of my people, and he often reported how I would plan out everything 

 at night and start in an entirely different direction the next morning. 



It was all taken with pleasant equanimitv- by Clark, and I only 

 learned of it all afterward from the report of his letters. 



He carried the "big Dana" as we called it then, Dana's Manual, 

 and stvidied it faithfully all the way. He took the fullest notes and 

 collected abundantly, and as we studied from Staffa through Scotland, 

 York, Durham, Lyme Regis, Cornwall and down to the Lizard; and 

 as thoroughly through Germany and Switzerland ; he had good oppor- 

 tunity for very varied geological work. 



At the end I advised him to study with Zittel in Munich as the best 

 place for paleontological and stratigraphical work, and he made a 

 fine thesis on taking his degree. 



Now Remson and I had worked together in Gottingen; Professors 

 Harmon Morse and George Huntington Williams were old pupils 

 of mine and so I was naturally interested in Science in the Johns 

 Hopkins, and when Williams needed an assistant I urged Clark for 

 the place, especially, I suggested, because he would never encroach 

 on Williams Optical Lithology work. 



And so he started on his remarkable career in Maryland. 



He married into another old New England family. His wife was 

 Ellen Clark Strong, daughter of Edward A. Strong of Boston, and 

 through her mother descended from the CI arks of Dorchester and 

 Northampton, and so his four children Edward, Helen (Mrs. H. 

 Findlay French) Atherton and Marion are of the purest strain of 

 puritan descent. His wife by her fine artistic ability was of much 

 help to him, especially in coloring his maps. 



It is the more remarkable that this true New England Yankee 

 should have so completely captured the southern State of Maryland.
