Although the locality selected had been partially lumbered, 

 it was favorable for study as the conditions were otherwise 

 undisturbed and it was almost uninhabitated. The reptile- 

 amphibian fauna Avas meager but an effort was made to work 

 thoroughly all of the habitats so that the list of species is 

 probably nearly complete. One species, Clemmys inscnlpta, 

 was added to the known fauna of the state. - 



The country about the iManistiquc River is a sandy plain 

 with atternating swamps and sand ridges. In the northern 

 part of the region, near Meesic Lake, there are morainal 

 ridges, two of which were studied. The flora of the plains 

 may be divided roughly into three types, the river flood-plain, 

 swamp, and sand ridge types. The flood-plain forest is domin- 

 ated by the maple, yellow birch, elm. balsam and hemlock. 

 The swampy areas subjected to flooding are occupied largely 

 by grasses and sedges and are fringed with tag alder. The 

 wooded swamps are of two general kinds, those dominated by 

 the arbor-vitae and those occupied by the tamarack, whits 

 spruce, balsam, jack pine, and associated bog plants. The sand 

 ridges were evidently originally clothed with the white pine 

 forest, but this has been largely removed and the forest now 

 consists of jack pine, paper birch, poplar, balsam, hemlock, 

 white spruce and tamarack with a few white pines. On the 

 moraines the beech, maple, yellow birch and basswood are the 

 dominant trees. 



The Manistique River, about a hundred feet wide at this 

 point, is a swiftly flowing stream, which varies rapidly in 

 depth anrl meanders greatly. AMiile the banks are usually 

 high, there are frequent depressions representing the ends of
