166 Rhodora [SEPTEMBER 
specimens of each were collected, without seriously affecting the 
supply. There were also good colonies of Monotropa Hypopitys L., 
bright scarlet instead of golden yellow, their prevailing color. Along 
a brook were splendid planté of Phegopteris hexagonoptera Fée, only 
waiting the hand of the collector to transfer their beauty to the herba- 
rium. 
Reluctantly we left these woods, and investigated some of the mill- 
ponds beyond East Killingly, near the Rhode Island line. Two of 
these were well filled with Myriophyllum ambiguum. Nutt., var. capil- 
laceum, Torr. & Gray, while Brasenia was the prevailing plant in the 
others. ‘The largest pond, Chestnut Hill Reservoir, was covered with 
the peltate leaves, which concealed the water and gave a peculiar 
leathery effect to its surface. I finally secured a specimen of this 
slimy plant, with leaves uneaten by the insects. Along the roadside 
thickets near the ponds were large quantities of A pios tuberosa Moench 
both in flower and fruit, and occasional plants of Solidago Ellotti 
Т. & С. just coming into bloom. 
Our next point was a steep unnamed hill near Elliotville, which we 
had visited in 1903. The eastern side of this is a big cliff of slightly 
metamorphosed sandstone, varying from 20 to 60 feet in height, with 
its white escarpment broken by fracture planes and caves, far surpass- 
ing in natural interest the more famous Wolf Den region of Israel 
Putnam in the adjoining town of Pomfret. In the woods here grew 
an abundance of Clematis verticillaris DC. апа Oryzopsis melano- 
carpa Muhl. ‘The westerly side of the hill proved ordinary and unin- 
teresting, except for a curious side-hill peat-bog, caused probably by 
some hidden spring. Mr. Spalding has since found a large tree of 
Betula papyrifera Marsh on the southwest corner of this hill. 
Whetstone Brook flows through the little valley below, on its way 
to join the Quinebaug River. In one of its tributaries grew Sium 
Carsonii Durand, but it did not seem to flourish in the main brook, 
where the water was too deep or the current too swift for this lazy 
degenerate of a worthy type. 'The brook gets its name from the 
easily cleaving, fine-grained sandstone of the region, and flows through 
rather ordinary meadows full of Carex stricta Lam., to the exclusion of 
most other species. There were fine colonies of Sparganium ameri- 
canum. Nutt. in some places, and in others there were Xyris flexuosa 
Muhl., Peltandra, Decodon, and Rhexia. At our 1903 visit we found 
_ large quantities of Ranunculus aquatilis L. var. trichophyllus Gray,
