The Lelation of Mollusks to Fish im Oneida Lake 25 
ing soundings. It is a pleasure here to acknowledge the aid 
afforded by this map and to say that it was found ainiformly 
accurate. (See Fig. 1.) All stations were examined care- 
fully, either by wading or from the rowboat where the water 
was too deep for wading. A single station received from an 
hour to a day’s time, according to its importance. A. repre- 
sentative collection of the biota from each habitat has been 
preserved in the collection of the New York State College 
of Forestry. ‘The fishes examined for their stomach contents 
were largely collected by Doctor C, C. Adams and Professor 
T. L. Hankinson during parts of August and September. 
They were mostly from ‘the same feealibies as the mollusks. 
The collecting apparatus consisted of Walker dredges, dip 
nets, water telescopes, vials and bottles of many sizes, mason 
jars and tin containers for large specimens. The photo- 
graphs were all taken with a 5x7 camera. A crowfoot dredge 
(Figs. 49, 50) four feet in length, made in a manner similar 
to those*used on the Mississippi River, was operated success- 
fully for collecting the clams from the deeper parts of the 
lake. This was also found useful in gathering samples of 
the bottom flora. To insure accuracy the description of each 
habitat, and the records of the presence of mollusks on vege- 
tation, were dictated to an assistant in the boat while the 
collector was wading about or making observations from the 
boat. 
Acknowledgments. These studies have been carried on 
under the direction of Doctor C. C. Adams, Forest Zoologist 
of The New York State College of Forestry, and to him and 
to Doctor Hugh P. Baker, Dean of the College of Forestry, 
the writer is indebted for the opportunity of carrying on 
these interesting investigations. The author is especially 
indebted to Doctor Adams for counsel and suggestion during 
the progress of the work which have materially added to the 
usefulness and value of the report. Professor T. L. Han- 
kinson, of the Eastern Illinois Normal School, Charleston, 
Illinois, has identified the fishes and has critically reviewed 
the manuscript of the chapter on ‘ Mollusks as Food of
