522 WILLIAM SMITH CLARK. 



large assortment of seeds of plants already known, but of special value 

 to Massachusetts from the high latitude from which they were selected. 

 Nothing escaped his scrutiny ; and on the side of Mount Tieni, at an 

 elevation of 3,200 feet, he discovered a new lichen, named by Profes- 

 sor Tuckerman, in his honor, the Cetraria Clarkii. The seeds of the 

 umbrella pine, the Ciadopetis verticellata, which previous to his visit it 

 had been difficult to obtain on account of the veneration in which the 

 tree was held by the natives, he procured in large quantities, sending 

 a man far up into the mountains to fell a tree and gather the cones 

 before they opened and scattered their seeds. 



President Clark received the degree of LL. D. from Amherst College 

 in 1874. He had been a Fellow of the American Academy of Arts 

 and Sciences since 1868, was a member of the Massachusetts Horti- 

 cultural and New England Agricultural Societies, honorary member 

 of the Massachusetts Society for promoting Agriculture, and resident 

 member of the New England Historic Genealogical Society. He 

 was author of the following papers in Liebig's Annalen : " Ueber 

 Chlormagnesium-Ammoniak," 1851; "Analyse des Steinmarks aus 

 dem Sachsischen Topasfels," 1851 ; and "Analysenvon Meteoreisen," 

 1852. He contributed the following articles to the Annual Reports of 

 the Massachusetts State Board of Agriculture : " Report on Horses," 

 1859 and 1860; "Professional Education the Present Want of Agri- 

 culture"; "The Work and the AVants of the Agricultural College," 

 1868; "The Cultivation of Cereals," 1868; "Nature's Modes of 

 distributing Plants," 1870 ; " The Relations of Botany to Agriculture," 

 1872; "The Circulation of Sap in Plants," 1873; " Observations on 

 the Phenomena of Plant Life," 1874; and "Agriculture of Jajian," 

 1878. He translated, for use in the Massachusetts Agricultural 

 College, the Blow-j^ipe Manual of Professor Scheerer, 1869. 



Following the investigations of Hales in the early j^art of the 

 eighteenth century, he carried on a series of novel experiments, in 

 1873-74, relative to the circulation of sap in plants, and the expan- 

 sive force exerted by the vegetable cell in its growth. The squash he 

 had selected for observation, in its iron harness, lifting five thousand 

 pounds before it ceased to grow, excited attention far and wide, and 

 was visited by hundreds. But his best work was as an educator. The 

 years spent as Professor in Amherst College and as President in the 

 Massachusetts and Japanese Agricultural Colleges were not in vain. 

 Bringing to the lecture-room that intense enthusiasm and personal 

 magnetism so characteristic of the man, he quickly established a bond 

 of sympathy between teacher and scholar that was never broken. He
