the rustic bridge. Here and along most of the north shore, the 

 shallow shoreward waters were filled with large irregular stones, 

 some projecting a little. The shore itself was a grassy bank a 

 foot above the pond surface. The area of submerged stones 

 along the shore extended out from 3 to 6 feet beyond which 

 the water was deeper and the bottom muddy. 



Station 16. This station was located about 30 feet west of 7, 

 or half way between it and the bridge, at the point where 

 this shore projected out farthest. It was established solely 

 because of the discovery of fresh-water sponge on a stone at this 

 place. 



Station 8. This station was located on the south shore of 

 the large pond just opposite the west end of the island. The 

 water was fairly deep even close to shore, and the latter a 

 grassy bank rising steeply to form a hill. Some large, submerged 

 stones made a rocky border similar but narrower than that on 

 the opposite shore. 



Station 9. This station was located at the northwest end 

 of the lake just west of the small island over which passed the 

 rustic bridge, just south of which it was. The water was very 

 shallow, the bottom muddy and with some sand and debris 

 accumulated there. But the layer of mud here and north of the 

 bridge, throughout the northwest arm of the lake, (which was 

 also shallow) was not very deep. But beyond the end of the 

 little island, the bottom had a declivity and beyond that, as 

 elsewhere in the large pond proper there was a deep bottom 

 layer of dark brown or black mud. Only a part of the shallowest 

 part was taken at this station. There algae and some grasses 

 grew. 



Station 10. This station was located at the southwest end 

 of the large pond, directly around the iron pipe that was the 

 outlet of the pond. The water was shallow, the bank and 

 bottom of clay with a few stones submerged near shore.
