LATER YEARS 409 



who knew about corals were connected with the editing: 

 of the report on the boring at Funafuti, which had not 

 yet been published, and could not be anticipated. 



In the spring of 1903, Agassiz proposed to Professor 

 H. L. Clark that he should collaborate with him in his 

 work on the Echini. This proposal was accepted by 

 Professor Clark, who became a member of the Museum 

 staff, and most of the Echini collected on Agassiz's 

 trips after 1891 were studied in collaboration, and pub- 

 lished with those collected by the Albatross in Japan 

 and Alaska under the title of : " Hawaiian and Other

 posed memoir on Echinoneus and Micropetalon, pre- 

 pared for publication by A. M. Westergren, appeared 

 in 1911. The condition in which the material for the 

 last-named publication was left, illustrates well Agassiz's 

 methods of work; for although he had been contem- 

 plating it for some time, and the illustrations were near- 

 ing completion, yet not a scrap of text was to be found. 

 Nevertheless, it was probably nearly ready for the press, 

 for Agassiz, like his father, had the habit of carrying his 

 work in his head, indeed, he often carried along in this 

 way and at the same time several pieces of work. 



He was greatly bothered in the summer of 1903 by 

 the old trouble in his leg, brought on again by over- 

 exertion at Calumet that spring, while on his tours of 

 inspection underground. About the middle of June he 

 writes from Newport : —
