The lake regions north of the City have always proved attractive 

 fields to collectors. The Lamberton Lake region consists of an 

 almost unbroken chain of lakes or marshes, enclosed by bluflFs of 

 sand loam, wooded with oak. The lakes are Lamberton and Mud 

 Lakes with their creek regions; Hound with its marsh; Button, 

 Soft-water, and Morgan. These lakes are bordered by open 

 marshes eitlier of sphagnum or muck underlaid by some marl. 

 Much marsh land about Lamberton and Round Lakes has been re- 

 claimed by deepening Lamberton Creek and thus lowering the 

 lakes. The marshes are overgrown with sedges and low shrubby 

 jdants; as, shrubby St. John's-wort, dwarf birch, low willows, etc. 

 This lake region is the home of the following species:
