A good supply of several forms of //ex was gathered, in addition 
to Spirea salictfolia, S. tomentosa, Cassandra calyculata, Polygonum 
emersum, and Vaccinium corymbosum, var. amenum. Vaccinium 
disomorphum, so plentiful two years before, the taste of whose fruit 
seems still to linger, was not observed. At that time the fruit was so 
plentiful that its weight bent the bushes almost to the water's edge. 
Pushing off again, we were soon among colonies of Xyris Caro- 
“iniana, Eviocaulon septangulare, Oxycoccus macrocarpus, Eleocharis 
olivacea, found nowhere else in Pennsylvania, and Juncus pelocarpus 
found at one other station in the State. Winding in and out among 
the bushes of Cephalanthus occidentalis and clumps of Nesea verti- 
cillata, which form a sort of breakwater, we hove in sight of 
‘‘ Stumptown,” as it was promptly christened, near the upper end 
of the lake. It seems at one time to have been dry, or as near 
dry land as is possible there, for stumps are very plentiful, and so 
are lilies, their pretty white and golden cups resting lightly upon 
the surface of the water. Sarracenia purpurea was searched for, 
but in vain, although it is found there earlier in the season. An 
almost submerged log near the shore is headquarters for Drosera 
rotundifolia and D. intermedia, var. Americana, the two sometimes 
growing matted together. Another landing was made, and fine 
Specimens of Aster corymbosus, A. linariifolius, A. undulatus and 
_other plants were collected. A hasty investigation of the opposite 
or north shore yielded Polygonum hydropiperoides and Potamogeton 
Nuttallii, The lengthening shadows warned us that it was 
time to suspend operations, and further investigation was aban- 
doned until next day. 
Early the following morning we were out on the lake, getting 
@ good supply of things that had merely been sampled the day 
before, and looking out for new treasures. Cicuta bulbifera, Bah- 
meria cylindrica, a form of Bidens cernua which I have seen no- 
where else, and Coreopsis discoidea, held sway over a patch of peat. 
Aster undulatus, with larger flowers than usual, and thin, broad 
leaves, several forms of A. cordifolius, A. lateriflorus, var. hirsutt-— 
caulis, a small flowered form of Solidago arguta, and a form of the 
€xceedingly variable //ex verticillata were collected. In the hasty 
Search over a field, only one plant of Guaphalium decurrens was 
found, but on the edge of the woods were good fruiting specimens oe
