its volume is manipulated in the interests of the mills lower down in 
its course. Water is now high, now low; and when it is suddenly 
lowered (often reduced. to isolated pools with barely a trickling 
streamlet between them, as I saw it in July and August) the rocks 
are left high and dry, and such delicate aquatic organisms as stone 
fly nymphs die of evaporation. I found such animals chiefly in the 
small side streams. The fauna of the river itself between this dam 
and the lower tributaries is mainly reduced to such forms as live in 
the bottom pools. I found the rocks in the channel of the stream itself 
not less barren of life than was the artificial retaining wall behind 
the hatchery [shown in pl. 4]. Trap lanterns set out back of the 
hatchery at this place attracted few insects besides midges and 
crane flies and these probably came from pools of the stream, or 
from wet places in the surrounding woods. However, I maintained 
all summer with somewhat better results, a trap lantern at a place 
half a mile farther down stream on the west side of the town at a 
point convenient to the cottage (Camp Sakheywey) in which [| 
spent the summer. Here the lantern attracted numerous May flies 
(among them the only specimens of Ephemera seen) and big species 
of caddis flies (Phryganea and Neuronia). Along shore on the 
deeper side of the river below this place indifferent fishing was 
indulged in by some of the natives. I saw only chubs, suckers and 
bullheads taken by them. 
Old Forge pond [map 2, |]. Neither is this body of water 
in a state of nature. By the building of the dam its out- 
lines have been altered and its depth has been increased. ‘The 
water front of Old Forge is here, and the shore along the town 
is lined with wharves and all the other shores are dotted with 
cottages. Wintergreen point, which projects boldly from the 
northward shore, directly in front of the town, has been stripped 
of its forests to open a vista up the channel toward the chain of 
lakes in the distance. Nevertheless, the level of the water is 
fairly constant now, and in the less frequented portions condi- 
tions are quite natural and the life of its waters is very little dis- 
turbed. The main path toward the lakes of the Fulton chain is 
so traversed by pleasure craft of all sizes that nowhere else may 
one get a better view of the procession of pleasure seekers to the 
great “North Woods” [pl. 5]. Still in the coves which receive 
the currents of the mountain brooks entering on either side of the 
channel there is abundance and variety of both plant and animal 
life. At the hatchery pier near the outlet, there is an extensive
