abundance being in a bay that was a spring-fed swamp before 

 the lake was formed. This difference is in the number of 

 species and in abundance as well, only a few,, such as Eleocharis 

 acicularis and the Mermaid-weed, Proserpinaca palustris, being 

 abundant in all the lakes. Thirty-seven species are found in 

 First Lake, twenty-four in Second Lake and sixteen in Third Lake. 

 All of the plants found in Second Lake are also found in First 

 and all those in Third are also in both Second and First Lakes. 

 An exception may be made in the case of Elodea, — -formerly 

 abundant in First Lake, it seems to have entirely disappeared 

 from there, but has become common in Second and Third Lakes. 

 Fifteen of the plants found are typical shore plants, growing in 

 the water with the plant mostly above water, such as cattails, 

 burweed, pipewort, water plantain, etc. Nine of the plants 

 are rooted with the leaves floating or slightly raised above the 

 surface, as water lilies, water shield, floating heart, etc. Seven 

 of the plants are rooted and entirely submerged, as Elodea, most 

 of the pondweeds and water milfoil. Six are usually free floating 

 plants, as the purple and large yellow bladderworts, and duck 

 weed. In First Lake the new area added by the raising of the 

 level of the water has been occupied chiefly by the moving in 

 of plants formerly growing in the shallow water, so that the 

 plants are now growing under conditions similar to their original 

 ones. A few plants have seemed unable to move and are 

 growing under abnormal conditions. Eleocharis Rohhinsii is 

 found only at one point along the shore, and there in water 

 about four feet deep, evidently where it had been growing before 

 the level of the water was raised. Now the flowering stems reach 

 only one or two inches above the surface, the submerged leaves, 

 about eighteen inches long, are far below. Peltandra virginica, 

 though growing commonly in shallow water along shore, is also 

 found in places in water over three feet deep where there was 

 originally only a swampy margin . Water milfoil , commonly float- 

 ing free in great masses or rooted and the stems floating near the 

 surface, also grows rooted in six feet of water, with the stems never 

 reaching the surface. 



The floating plants, or such as may break free and float, 

 as the purple and yellow bladderworts, Elodea and naiad are 

 the most abundant plants in Second and Third Lakes. The 

 white water lily which is abundant in First Lake was repre-
