August, and we went to it then only because it offered an exceptionally 

 good opportunity for the study of the insect food of the brook trout. 



Little Green pond is a beautiful sheet of water half a mile long and 

 nearly as wide, with steeper banks that are nearly destitute of aquatic 

 vegetation, excepting in the little bay on the north shore, and with a 

 bottom of clean white sand. The vegetation of the bay is somewhat 

 similar to that of Bone pond, with the addition of the white water lily, 

 Castalia odorata (Dryand.) Woodv. & Wood. Wintergreen, 

 Gaultheria procumbens Linn., and twin flower, Linnea 

 b o r e a 1 i s Linn., and the pretty little Dalibarda repens Linn., as 

 well as big tufts of the lichen commonly known as " reindeer moss," 

 occupy the dry and abruptly sloping south shore. Little Green is not a 

 trout pond. Frequent plantings of fry have resulted in nothing. Little 

 collecting was done there, for it seemed very barren of insect life. 



Little Clear pond (pi. i, 2) is nearly a mile and a half long, a mile wide, 

 and is said to be in places more than a hundred feet deep. It is worthy 

 of a more pretentious name. Owing to irregularities of contour, it has a 

 very long shore line, that varies in character according to the inclination of 

 the adjacent slopes. Conditions have been somewhat disturbed here 

 within recent years by the building of a dam at its outlet, that has raised 

 the water several feet, and caused it to encroach on the surrounding 

 timber, which now stands dead along the shore. Aquatic shore vegeta- 

 tion is not abundant except in a few places. Two places were selected 

 in Little Clear for more or less regular collecting, the bay in Blueberry 

 island near the west shore, and the outlet. 



Blueberry island is a small sandy spit of burned-over land, now 

 covered with a thin growth of poplar trees, with broad mats of moss and 

 lichen, with extensive clumps of blueberries, and with other clumps of 

 Labrador tea overhanging its shores, specially in the bay. The banks 

 are strewn with decaying trunks of fallen hemlocks, and in the narrow 

 channel between the island and the hill to the westward dead trunks are 

 still standing in water of considerable depth. The water is shallow for a 

 little distance in the bay, and contains a sparing growth of aquatics, such 

 as yellow and white water lilies, sedges, and cat-tails. Not a great many 

 species of insects were collected from this bay, but some of these were 

 exceedingly abundant; as, Chauliodes rastricornis, and 

 species of Gomphus and of Tetragoneuria. 



The outlet of Little Clear pond offered considerable variety of situa- 

 tion in small compass. Its east shore was strewn with logs so thickly as 

 to be difficult of access with a boat except next the lake, where was a
