which are to be seen, here and there, patches of P. amplifolius^ 
Tuckerm., distinguished by its lighter yellowish hue, and broad leaves 
curiously twisted and curled. In one of the coves we came upon 
Nasturtium lacustre^ Gray, (in flower and fruit). I had collected it 
during a former visit (Sept, 2, 1879) at a single station, but now it 
was observed at various places from the head of the lake to the outlet. 
The leaves, both those above the water and those beneath, are very 
easily detached, so that it is difficult to make complete specimens. 
At this spot we fished up half a dozen stalks of Ranunculus aquatilis^ 
L., var. divaricatus^ Chaix. (in flower), and Potamogeton luccns (in 
flower and fruit). The opposite border of the cove is lined with a dense 
growth of Saururus cernuus^ L., conspicuous by its nodding spikes of 
fragrant flowers. This plant is common all along the Paulinskill 
Creek from the lake to the Delaware, fifteen miles, but, strange to say, 
it has been observed, as yet, on that river, only at Trenton, about 
seventy miles further down. As we passed around the main bluff, or 
promontory, some bushes oi Myrica cerifera were seen on its slopes, 
and at its base, a solitary Salix lucida, Muhl. From this point we 
proceeded over a considerable bay to the northeastern end of the 
lake and glided into an area, several acres in extent, occupied by 
Nelumbium luteum^ Willd. The vernation of the leaves is involute. 
Some project themselves above the water, whilst the others stop at 
the surface. These latter in unfolding assume the form of a bowl, or 
basin, or inverted skull-cap, and are very pretty objects as they float. 
: When fully expanded, they are of a deep green color above and lie flat 
on the water, which, cast upon them by the dip of an oar, rolls and 
divides itself like quicksilver, emitting a brilliant silvery light. The 
cause of this phenomenon is worthy of investigation. The leaves of 
Orontium aquaticum^ L., behave in the same way. To our great dis- 
appointment not a single flower could be discovered in the entire 
colony. It may have been too early for their appearance, or else the 
summer lodgers of the neighboring hotels and farm-houses had gath- 
ered them all, A little further to the east, I looked for Helcocharis 
<iiiadranguiata,V^. Br., where I had discovered it September 2, 1879. 
It was now in flower, and still plentiful. In coasting back along the 
eastern shore we found Taxus baccata, L., var. Canadensis. Gray, as 
abundant on the rocks as in September, 1879. On one of the undis- 
turbed and untilled islets In the middle of the lake, it was a surprise 
to see Solanum Dulcamara, L., flourishing luxuriantly amongst the 
aboriginal vegetation. 
After dinner, at 2 p.m., Mr. P. P. Clarke drove me oyer from 
Stillwater to Blairstown, six miles, in order to take the evenmg tram 
at that place. For three miles along the road the eye was attracted 
by the frequent occurrence of Zanthoxylum Aniericanum, Mill., Rosa 
rubiginosa, L., and Oiicus pumilus, Torn Midway on the route, we 
turned into a lane, to the left, and soon reached a lakelet of oblon 
shape and about three-fourths of a mile in length called White Pond 
A white line of shell-marl all around its margin mdicates the origin of 
the name, it lies in Warren County close to its Sussex boundary I he
