SWAMP A T ADAMS BASIN. 



The swamp near Adams Basin has furnished many interesting 

 species. It comprises several pieces of low land separated by culti- 

 vated fields, and in extent, including the fields, is about half a mile 

 from north to south, and nearly as far east and west. The land sur- 

 rounding it is rolling, and on the east are low hills, the termination 

 of the range which may be traced south-eastward to the Pinnacle 

 hills at Rochester. Underlying, at a depth of fifteen feet, is the 

 Medina sandstone. The water supply is from several small streams, 

 which, passing through the swamp, finally empty into Salmon creek. 

 Numerous springs also give a never-failing supply, especially to the 

 lower swamp. Efforts have been made, with some success, to drain 

 the land, and probably before many years this station will be entirely 

 lost. A variety of forest trees — maple, ash, oak, birch and tamarack — 

 formed a dense wood formerly, but, except in the lower swamp, few 

 of the larger trees remain. Their space has been taken up in the 

 middle swamp by a luxuriant growth of Myrica cerifera. The lower 

 swamp rises slightly along the southern edge, and here beech, hickory 

 and white pine are growing. North and east it is lower and covered 

 with tamarack, birch, hemlock, and an abundant growth of Rhus vene- 

 nata. The plants are those peculiar to cold bogs, and many are not
