darter, a few young of each ; Johnny darter, 1 ; map turtle, 1 young ; 

 crawfish, 5. 



October 23, forenoon. Stations, 601 to 607, in upper half of 

 Outlet, in open water with 25-foot seine. Air, 65 ; water, 64. 



Catch: Straw bass, a great many (75 in first haul), each 4 to 

 6 inches long, a few larger; bluegill, many small ones; warmouth, 

 several; red-eared sunfish, many, medium size; pumpkinseed, 3 

 small ones; rock bass, 5 young; grass pike, 2 young; mud min- 

 now, 1 ; Fundulus dispar, 3 ; Johnny darter, Iowa darter, and least 

 darter, several of each; yellow cat, several young. Also a few 

 larval salamanders and cricket frogs. 



November 28, morning. Stations 608 and 609, with 15-foot 

 seine, in front of Barnes cottage just north of Arlington pier, for 

 skipjacks of which about 2 gallons were caught. With them were 

 a few small straw-colored minnows and blunt-nose minnows. 



Besides the more or less regular seining operations detailed in 

 the preceding paragraphs, considerable miscellaneous seining was 

 done at odd times for diverse specific purposes, among which may 

 be mentioned getting material for studies of structure, fish-food, 

 parasites, growth, spawning, enemies, coloration, variation, asso- 

 ciation and distribution. In these cases the seine hauls were not 

 recorded in the regular series and, usually, only those matters 

 especially under consideration were noted. 



This miscellaneous seining, however, yielded much valuable 

 data on many of these questions. 



Late in the summer and early fall many hauls were made at 

 night, chiefly with a short seine and in shallow water along the east 

 side of Long Point. These operations demonstrated that there is 

 a general inshore movement at night, not only of the carnivorous 

 species but of other kinds as well; and many of the fishes caught 

 were of large size. Among those that were frequent in these night 

 catches were large-mouth bass, small-mouth black bass, dogfish, 

 walleyed pike, white sucker and water-dogs. All of these except 

 the sucker evidently come in shore at night to feed on the smaller 

 fry abundant in shallow water, as was demonstrated by an exam- 

 ination of many stomachs. 



Late in the fall and early winter considerable seining was done 

 with a small seine in shallow water both in the day time and at 

 night for the purpose of securing study material of the small min- 

 nows which it was discovered congregate in vast schools at that 

 season. Some of these great schools, consisting of thousands of 

 fish, were found to be made up chiefly of straw-colored minnows 

 with fewer of the variable-toothed minnow, a few of the Cayuga
