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 pi. 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 I 

 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 kkes 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" [pi. 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
