leaving the open second growth timber surrounding tlie camps 

 and cottages. A marsh of reeds and rushes borders the hd<e's 

 inlet at its eastern end and its outlet at the western end, while 

 several smaller marshes cccur at various points along the 

 shore. The one at the west end of the lake is about 1^'/. miles 

 long and nearly as wide, through which winds a narrow, 

 sluggish stream almost choked in places by the rushes. 



Two young men staying at the camp were found to be 

 ardent bird hunters, and together we worked over a part of the 

 shores and bluffs near the camp and a little of the surrounding 

 country where were seen a number of the common field birds 

 which were not seen at all in the immediate vicinity of the 

 lake. Many of the birds were seen feeding young recently 

 out of the nest, while a few nests containing eggs or young 

 were found. All the birds seen probably breed in the vicinity 

 of the lake or in the surrounding country. 



On the lake shore near the Y. M. C. A. camp was the elec- 

 tric pumping station for supplying water to the Yerkes Ob- 

 servatory, which is situated on the top of the bluff. A lightning 

 arrester in a wooden box about a foot square was fastened 

 about 18 feet from the ground to the top of a pole carrying 

 the electric wires, and just outside the pumping station. In 

 the side of this box during some previous year a Flicker 

 (probably) had bored a gcod-sized hole, which a pair of 

 Crested Flycatchers had taken possession of for a home, and 

 during part of my stay were feeding young which grew large 

 enough to leave the nest shortly before my departure from 

 the camp. The pole stood near the lake shore at the inter- 

 section of two paths along which hundreds of people passed 

 every day. The birds were very tame, repeatedly carrying 

 food to the young wdiile a number of people were standing 

 watching close bv. 



About a half mile west of the camp 1 discovered the nest of 

 another pair, this time in a cavity about 40 feet up in a large 

 hard maple which stood by the boat-landing to one of the 

 large summer cottages. This pair also were feeding young in 

 the nest. A third pair was found at home in the dead top of 

 a large oak on a hill at the west end of the lake, but which
