region. The year following his residence at Ann Arbor 

 found Mr. Clifford at Johns Hopkins Hospital, studying 

 bacteriology, accompanying the Johns Hopkins expedition 

 to Jamaica, in the spring and summer of that year. The 

 three years following he was Instructor in Botany at 

 Swarthmore College until the end of his third year, when 

 lie was allowed leave of absence for four months, which he 

 spent in Louisiana, British Honduras, Yucatan, Guatemala 

 and Spanish Honduras. In the spring of 1894, Mr. Clifford 

 was appointed Forester of the Geological Survey of New 

 Jersey, and has since been devoting his entire energies to 

 the prosecution of this laudable object, the protection and 

 reforestratiori of the timber lands of New Jersey. As editor 

 of The Forester, he has had the opportunity of molding public 

 opinion both in his own and neighboring states in further- 

 ance of the forestry cause. His " Report on Forestry " from 

 the Annual Report of the State Geologist, for 1894, is both a 

 valuable contribution to botany, especially ecological botany, 

 and to forestry. Mr. Gifford, having pursued the forestry 

 course, in the German Forestry School at Munich, will take 

 his degree from that institution in 1898-'99, as a Doctor of 

 Forestry. A few articles from his pen have appeared in 

 Garden and Forest, as follows : 



1. " Distribution of the White Cedar in New Jersey." IX : 63. 



2. " Reforesting Waste Lands in Holland." IX : 4'23.
