plankton, has found if floating Imt onco. At Turkey Lake it is said to 

 float in srreat <inantities. tbo -whole lake appearing^ cnnvded full of dark 

 srreen spheres the size of a large i)inlicad. and on a short visit to Tippe- 

 canoe Lake I noticed the same piienomenon. I have not had opiwrtunity 

 to compare the richness of vegetation of Turkey and Tippecanoe Lakes 

 witli that of Eagle Lake. It is possHile that the condition Eivularia 

 assumes depends tipon the abundance or scarcity of plants which will 

 serve as places of attachment. In assuming this attached position it es- 

 cai)es the plankton nets, and so its abtmdance is lial)le to be underesti- 

 mated; for as there is difficulty in manipulating the net among tlie water 

 Aveeds. direct comparison of its abundance would be impossible to obtain. 



A.S an agent in the dissemination of seeds the lake acts only to a limited 

 extent, as a floating seed would need sufficient surface projecting above 

 the water in order to be wafted far. ;Many such seeds as acorns, hazel 

 nuts and butternuts were floating in the water, but all of them were de- 

 cayed. In the case of winged seeds, however, it was different. A number 

 of small seedlings of the soft maple were found growing along the shore 

 about high-water line, and the seeds had evidently been deposited there 

 by the waves. The year of 1899 was somewhat noteworthy for the very 

 heavy crop of elm seed, especially white elm. In the early summer of that 

 vear. in the vicinity of Fort Wayne, the writer noted woodland ponds, 

 the surfaces of which were entirely covered with the seeds of this species. 

 In the same summer, but later, there was found at the high-water line of 

 the lake just north of the laboratories a row of small seedling elms gi-ow- 

 ing as thickly as they could stand. There was another long, thick i-^w in 

 a. corresponding position along the southeast shore of the lake. In the 

 summer of 1900 quite a number of the elms were found. They had in- 

 creased well in size and looked quite thrifty. If undisturbed they: may 

 form the beginning of a forest, much like the present low-ground forest 

 'along the lake shore. There was no elm seedlings of 1900 noted: the crop 

 of seed in the fore.sts was not by any means so large during that summer. 



Below is appended a list of plants noted in the vicinity -of Eagle Lake. 

 The list of plants occurring in the neighboring forests, or at any distance 

 from the lake, is not intended to be complete, as observations- werevjnade 

 here only incidentally as time could be taken from the lake work. It is 

 believed that all the phanerogams of the lake have been noted. The order 

 and synonymy is that of Britton and Brown's Illustrated Flora. -Wher- 

 •ever these names differ from those of the sixth edition of Gray.'S' Manual
