About half a mile beyond this settlement, or a mile from 
Ingliside, is the most remote of the summer settlements, consisting 
here of but two cottages. They are located in a hardwood forest 
and have practically no cleared land around them. Here there is 
no introduced flora whatever, although some daisies planted 
around a veranda show a slight tendency to spread. Just behind 
these cottages along an abandoned logging road nineteen species 
of introduced plants occur. 
These data, showing the reduction in the introduced flora 
from 42 species to none in a distance of a ae indicate clearly 
the inability of the species to migrate with effective human 
aid. The same feature is illustrated by the flora around or near 
Bryant’s hotel, on the south side of the lake. Here is a wagon 
road from Pellston, and during the summer months the travel is 
quite heavy. All vehicles stop at or near the hotel, and persons 
desiring to reach the farther cottages walk down the beach. In 
the immediate vicinity of the hotel nineteen species occur. These 
are: 
Polygonum Persicaria 
Polygonum Convolvulus 
Rumex elongatus 
Rumex Acetosella 
Chenopodium album 
Chenopodium hybridum 
Poa compressa 
Poa pratensis 
Poa annua 
Agrostis alba 
Phleum pratense 
Polygonum aviculare
