times, I felt a positive sadness when I realized that the great 

 visitation was over, and there was silence in the world again, and 

 all were dead that had so recently lived and filled the world with 

 noise and movement. It was almost a painful silence, and I could 

 not hut feel that I had lived to witness one of the great events of 

 existence, comparahle to the occurrence of a notable eclipse or 

 the visitation of a great comet. Then again the event marked a 

 definite period in my life, and I could not hut wonder how 

 changed would be my surroundings, my experiences, my attitude 

 toward life, should I live to see them occur again seventeen years 

 later.

THE BEHAVIOR OF FFNDULFS I1ETEROCLITUS ON 

 THE SALT MARSHES OF NEW JERSEY 



During the year 1914-'15 the writer was retained as consult- 

 ing zoologist to the department of entomology of the New Jersey 

 Agricultural Experiment Station and engaged in studying the 

 fish enemies of the salt marsh mosquitoes. At that time it be- 

 came evident that Funduhts hrt< roclitiis is the most important 

 predatory fish attacking the salt marsh mosquitoes of northern 

 waters. Much evidence of the efficiency of Fundtdus hcteroclitii^ 

 as a mosquito exterminator has already been published (Chides- 

 ter, 1916) . Certain notes on its behavior under varied condi- 

 tions have been amplified by more recent observations and are 

 herewith presented in connection with the problem of migration 

 in fishes. 



In New Jersey the fish were studied under natural conditions 

 for over a year on the salt marshes near the city of New Bruns- 

 wick. Through the report system of the state inspectors of the 

 Mosquito Commission, much important information was secured 

 regarding conditions in other parts of the state. Experimental 

 conditions were induced in the field by drainage ditches and in 

 the laboratory by the use of aquaria. Other studies were made 

 at Woods Hole, Mass., for several years during a portion of the 



Material and Methods 

 On the salt marshes where the chief study was made there 

 were numerous pools, some permanent, others easily differenti-
