Stone Cat {Schilbcodes gyrinus) 



A female stone cat, full of nearly ripe eggs, was taken as late as 

 July I, 1910, near the head of Quiver Lake near the east shore. 



Grass Pike (Bso.v vcruiiculatus) 



Large numbers of grass-pike fingerlings are easily taken in May 

 and June in Danhole's field. By the 25th of May, 1910, they had 

 grown to a length of 2 to 2^ inches, and were doubtless, before that 

 time, formidable enemies of the myriads of carp fry in the field, 

 practically none of which were over Y^ inch long on the first of June. 



Top-MiNNOW^s (Funditlus nofatits and F. dispar) 



On May 25, 191 1, about two dozen Fundidn^s notatiis, males and 

 females, were observed swimming actively, pursuing one another, 

 and occasionally jumping clear of the water, in weed-filled shallows 

 toward the head of Dierker Lake. Two males at times pursued the 

 same female, one trying hard to drive the other off. Examination 

 of the females showed the ovaries full of eggs of large size and loos- 

 ened from the membrane. 



Gravid females of Fnndidus dispar, on the point of spawning and 

 attended by males, were taken May 23, 191 1, in shallow water, full 

 of weeds and alga^, just outside of Riley Smith's Marsh, above the 

 head of Quiver Lake. 



SiEVERSiDE {Labidcstlics sicculiis) 



During the second week of June, 191 1, the fry of this species, % 

 to % inch long, were abundant, in schools, in water 2 to 3 feet deep, 

 on the ridge between Flag and Thompson's lakes. They swim near 

 the surface, with a very characteristic wriggling movement. They 

 seem to keep to the open spaces between the clumps of smartweed 

 and Potaiiiogcton. 



Speckled Crappie (Pouio.ris sparoides) 



May 2, 191 1, a nest of this species was found in water 10 inches 

 deep near the north end of Danhole's field. It was hollowed out 

 under the leaves of a water-parsnip, and surrounded by smartweed 

 and bog rush {J uncus). Some of the eggs were adhering to fine roots 

 in the bottom of the nest, but most of them were on the leaves of the 

 water-parsnip, at a level of 2 to 4 inches aliove the bottom of the nest.
