]>laiikton, h;is >fomul it floating? but oiico. At Turkey Lake it is said to 

 float in .creat (luantities. the whole lake appearins;- erowded full of dark 

 .yireeu spheres the size of a lariie i)inh('ad. and on a short visit to Tippe- 

 canoe T-ake I noticed the same phenomenon. I have not had opportunity 

 to compare the richness of vegetation of Tnrkey and Tippecanoe Lakes 

 with th<it of Eagle Lake. It is possible that the condition Rirnlaria 

 assumes depends upon the abundance or scarcity of plants which will 

 serve as places of attachment. In assuming this attaclu'd position it es- 

 capes the plankton nets, and so its abundance is lialile to be underesti- 

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

 weeds, direct comparison of its almndance wotild be impossible to olttain. 



As 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 Initternuts were floating in the water, but all of them were de- 

 cayed. In the case of winged seeds, however, it was dilfcM'ent. A numl)er 

 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 Avaves. The year of 1S99 was somewhat notewc^rthy for the vci-y 

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

 year, 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 i-ow of small seedling elms grow- 

 ing as thickly as they could stand. There was another long, thick row in 

 a coi'responding iwsitiou along the southeast shore of the lake. In the 

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

 creased well in size and looked ([uite thi'ifty. If mnlisturbed they may 

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

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

 of seed in the forests 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 were made 

 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
