186 Lake Maxinkuckee, Physical and Biological Survey 



inkuckee as at many of the small lakes of Indiana. At Eagle Lake 

 near Warsaw, this plant presented two distinct forms, one soft, 

 easily crushed and pale glaucus, and the other bright green and 

 very firm. The soft pale form was very rare at Lake Maxinkuckee, 

 but appears to be increasing considerably of late years. At Eagle 

 Lake, too, the bases of the culms were very frequently covered with 

 green sponges, while this was not at all common at Lake Maxin- 

 kuckee. The parts of the plants above water seem to die very 

 slowly and imperceptibly during the winter, and their bases under 

 water remain fresh, succulent, and green down to the white base. 

 On April 14, 1901, bases were washed up fresh and green. They 

 seem to be pulled up somewhat by ice cakes. On April 30 the 

 old bases were noted thickly coated with a much-branched fine 

 sort of alga. By May 3, the plants were observed sticking up well 

 out of the water in Lost Lake. On May 4 they were up and ready 

 to blossom near the Outlet in Lake Maxinkuckee, and were ob- 

 served in about the same condition May 10 in Green's marsh. By 

 May 20 they were in blossom. 



The rush-patches offer a retreat for small floating plants, and 

 the patch north of the Ice-houses contained Wolffia, Spirodela and 

 Ricciocarpus. This was the only place these plants ventured to 

 grow in the lake except in the sheltered region near the Norris 

 Inlet. Muskrats like to keep among rush-patches and use the 

 stems to some extent in their nests. 



40. THREE-CORNERED BULRUSH 



SCIRPUS AMERICANUS Persoon 



Very common, fringing the lake in patches wherever the condi- 

 tions were favorable, as about Long Point, in front of the Barnes 

 cottage, a small patch at Green's pier, a very long patch south of 

 Green's extending to Murray's, south of the pond or marsh south 

 of Farrar's, opposite the spongy spring hill on the southwest shore 

 of the lake, by the green boathouse near Norris Inlet, and from 

 Norris Inlet to beyond the Norris farm, where a long row of tall 

 willows comes down to the lake. From this point to Culver Bay 

 there is none, the descent of land to the water being too sudden. It 

 begins again in occasional patches where the road comes down to 

 the lake near Culver Military Academy, and a patch fringes most of 

 Culver Bay in front of the grounds. It grows east of the Palmer 

 House, and east of Lakeview Hotel and beginning again at the 

 railroad pumping station it extends in pretty continuous patches 

 to the Outlet. It seems to prefer a flatfish bottom of mixed marl,
