the salt water, it affords to the sportsman exciting play for 

 considerable time before it permits itself to be taken. 



Care will have to be observed that this valuable fish is 

 not exterminated in this lake. As railways render the 

 locality more accessible, the beautiful scenery must attract 

 tourists and sportsmen in increasing numbers and lead to 

 extinction of the fish unless the lake continues to be 

 periodically restocked with the fry, and fishing is permit- 

 ted under stringent regulations which are not only made 

 but are also properly enforced. 



Obituary. 



GEORGE HUNTINGDON WILLIAMS. 



George Huntingdon Williams died at Utica, N.Y., on the 

 12th of July, at the age of 38. He was born at Utica, and 

 graduated from the Utica Free Academy, entered Amherst 

 College in 1874 and took his first degree with the class of 

 1878. While in college he caught his enthusiasm for 

 geology from his teacher, Professor B. K. Emerson, and 

 spent a year in graduate studies at Amherst. 



He then went to Gottingen where he perfected his knowl- 

 edge of German and studied for several semesters under 

 Professor Klein. Leaving Gottingen he proceeded to 

 Heidelberg where he continued his studies in minerology 

 and petrography with Professor Rosen busch, taking his 

 Ph.D. degree — summa cum Laude — in 1882. 



The following year he became a Fellow in the Johns Hop- 

 kins University, where he was subsequently appointed 

 Associate, and in 1885 Professor of Inorganic Geology, 

 which position he held at the time of his death. 



Petrography and crystallography were the special de- 

 partments of geology which he cultivated, and his text- 

 book on crystallography is a lucid exposition of the methods 

 of research in this line. At the time of his death he was 

 at work on a treatise on the microscopic structure of Ame- 

 rican crystalline rocks. He was one of the best authorities 

 on these subjects in America, and served as oneof thejudges
