Mr. A. T. Beals remarked on slime-moulds collected during 

 the summer, with an introductor}^ sketch of the general mor- 

 pholog}' of the group, their natural habitats, and best methods 

 of preser\^ation. 



Dr. F. J. Seaver reported on a field trip to Elmsford, N. Y. 

 Glonium stellatum, a fungus not previously observed by him in 

 the local flora region, was among the plants collected. 



Dr. Alfred Gundersen made some observations on the flora 

 of the northeastern parts of the Catskill Mountains. 



The absence of trees common near New York, such as hick- 

 ories, locust, sweet gum and all oaks except the red, together 

 with the abundance of species such as fir and white birch, gives 

 to the higher regions of the Catskills a distinctly northern 

 aspect. 



Above 2000 ft. elevation in the region surrounding the Big 

 Hollow valley red oak was found only on the south slope, fairly 

 common up to and slightly above 3000 ft. elevation. White 

 pine and American elm were seen rarely and only on the lower 

 south slopes. Sugar maple, American linden and American ash 

 were more common on the south than on the north slope. Red 

 spruce, white birch, pin cherry and mountain maple were 

 common on both slopes; fir, hemlock, yellow birch, mountain 

 ash and striped maple most abundant on the north slopes, black 

 spruce occasional there ; these all grew up to or near the summit 

 of Black Dome, 3990 ft., third highest of the Catskill mountains. 



Chestnut, entirely absent from this part of the mountains, is 

 frequent on the Hudson valley slopes up to 2000 ft. elevation 

 and occasionally higher. WHiile the trees are usually attacked 

 by the bark disease, many seem to be in fairly good condition. 

 Another plant found only on the east side of the mountains is 

 mountain laurel, abundant in places between 1600 and 2200 ft. 

 elevation. 



It is well known that going northward there is an increasing 

 similarity in American and European plant and animal life. 

 Thus it is of interest that in the region studied the genera of 

 trees are just those of Norway, with the exception of hemlock 

 and fir, absent from northern Europe. Of shrubs two species 

 are the same in the Catskills and in Norway, juniper and alder . 

 (Alfiiis incana). In ferns and clubmosses there is a much greater 

 correspondence.
