Farther in these woods, that is towards the okler portion of the Point, 

 the woods become much more heavily shaded. Here the jack pines 

 were about equaled in numbers bj' Pinus resiyiosa. Scattering trees 

 of Pinus strobus of all ages were found and scrubby growths of Quercus 

 rubra and Q. coccinea were common. The heaths and sod disappear- 

 ed and the group of plants just listed was giving way to plants fitted 

 for shade. In the latter the leaves were larger so that the ground 

 could not be seen because of them, and the species were more meso- 

 phs-tic and showed better than the present upper layer the future of 

 the formation. The following mosses were common: Dicranium 

 jlagellare, D. fuscescens congestum, Polytrichum piliferum, Thuidium 

 virginianum .
