REPORT OF THE STATE ENTOMOLOGIST 1907 163 
At the outlet of the pond (the spot shown at the right hand ot 
the picture in pl. 6) was a bit of open water of wonderful beauty 
and interest whether one looked across its surface or down into its 
clear depths. A bed of callas fringed it, backed by a zone of sedges 
and clumps of alders. On the peaty bottom that was thickly 
sprinkled with brown plant stems, the agile nymphs of the May 
fly Siphlurus darted hither and thither and caddis fly larvae in 
abundance dragged and tumbled their big cobhouse cases about. 
Great loose masses of disintegrating alga-tinged gelatine, left over 
from the spring hatching of salamander eggs, draped all the 
branches of one large hemlock top, while a remarkably fine growth 
of fresh-water sponge of vivid green color covered another. It 
enveloped all the twigs and 
ran out in slender fingerlike 
processes beyond their tips, 
and these were beautifully 
displayed in the still water. oh‘: 
On the sixth of July a few JFeer 
winter buds were already de- 
veloped on the basal parts of us 
some of these sponge masses, : 
and by the aid of the spicules Fig 2 The fresh-water sponge Heteromyenia 
developed iim tae wallls Il Wag Pxeeety Om ncaa wore 
able to determine that the sponge is Heteromyenia ry deri, 
a species not uncommon in the east Atlantic States but one that 
rarely shows such luxuriance of growth. 
My notes on dragon flies farther on will show that some fine 
Cordulines were here, and Aeschnas. Dr Betten carried back to 
the hatchery and reared many caddis fly larvae taken from this 
pond. He visited the pond and set out trap lanterns on several 
evenings, but in each case the chilly, damp night air of so common 
occurrence in the Adirondacks, settled down at nightfall and his 
catches were exceedingly light. In other particulars than those 
mentioned the fauna of this pond seemed quite fairly comparable 
to that of other small bodies of water in this region. There were 
a few large diving beetles, and a few exceedingly small ones; a 
few back swimmers, many water boatmen, a few Ranatras, a few 
whirl-a-gig beetles and very many amphipod crustaceae (Gam- 
marus) of large size.
