mile distant from the hatchery. On it are located the new fish 

 ponds, a few hundred yards up the glen from its mouth. Here 

 the young trout are kept in the feeding troughs during the 

 summer after the water in the hatchery has gotten too warm for 

 them, and here in pens made in the brook itself, a number of 

 adult trout are pastured; they feed in part at least on the natural 

 forage the brook affords. Above the ponds for a little way the 

 course of the brook is steep and tortuous and its channel has 

 been undisturbed. It wiiids in and out among moss-grown 

 boulders, sweeps over little falls [pi. 7] that are draped with 

 long moss and lies still in little hollows that are but half exposed 

 to the sky above. Here was a most excellent collecting ground 

 for aquatic insects, and here were spent very many pleasant 

 hours of field work. Here we set our tent trap [pi. 8], to be 

 described farther on, and preserved its captures regularly for a 

 month. 



The Adirondack League Club road to Little Moose lake crosses 

 the brook about as far above the fish ponds as these are above 

 the shore line, and this crossing is an excellent collecting ground. 

 Butterflies and syrphus flies swarm here, about a few roadside 

 flower clumps. Along the roadway some fine dragon flies were 

 found coursing back and forth : it was here I took the only speci- 

 men I have ever seen alive of Gomphus ventricosus, 

 adding another to the list of species belonging to the fauna of 

 the State. Over a pool just above the bridge and under a leafy 

 canopy that is held aloft by two slender birch trunks, little white 

 and brown May flies, and midges, and crane flies congregated and 

 danced in the air up and down of late afternoons, and pale green 

 stone flies were to be seen running over the witch hazel leaves. 



Above the road the descent of the brook is more gentle and soon 

 its channel widens out into the '' Beaver Meadow." It is a bit of 

 upland marsh apparently formed above Beayer dams in aboriginal 

 times. Its level floor is built on sphagnum. It is dotted with 

 pitcher plants and plumed with cotton grass and ornamented in 

 some of the wetter spots by abundant yellow Habenarius. It is 

 not a wet marsh for the most part and it is being invaded by border- 

 ing shrubbery and scattered pale tamaracks, and it is traversed by 

 the sinuous alder-bordered brook, which here glides along over a 

 level bottom that is thickly strewn with brown peaty marsh 

 and silt. Springs from the marsh and from other lesser marshes 

 of similar origin situated farther up on the sides of Little Moose
