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 winds in and out among moss-grown 
boulders, sweeps over little falls [pl. 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 [pl. 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
