low wooded land, and higher wooded land. Observations were 

 made on the herbaceous, shrubby and arboreous vegetation, 

 including a count of the plants concerned with annotations on 

 their state of vitality. 



In the case of the herbaceous vegetation, with two exceptions, 

 the plants formerly existing in moderate profusion had been 

 entirely wiped out following the flooding. The fern, Onoclea 

 sensibilis, was sending up its leaves thru 20 centimeters of water 

 in two places and one patch of a species of Carex was maintain- 

 ing its clump of leaves below 17 centimeters of water, but had 

 not sent up a flowering shoot. A patch oi Lycopodium annotinuni 

 was still alive under 10 centimeters of water, but was obviously 

 dying. No other herbaceous vegetation was noted. 



The case of the former shrubs was hardly any better. It was 

 of course somewhat complicated by the fact that many — 

 perhaps most — had been cut off or uprooted to furnish small 

 material in the construction of the dam. Among the shrubs to 

 be expected were: 



Acer pennsylvanicum, Acer spicatum, Cornus rugosa, Diervilla 

 diervilla, Rhus radicans, Ribes spp., Salix discolor, Salix spp., 

 Taxus canadensis. Viburnum cassinoides, besides seedlings and 

 saplings of the tree species of the area. Of these, the living 

 seedlings or very small saplings (that is, not over i centimeter 

 in diameter) were only on large logs which were projecting above 

 the water and in no case were to be found at or in the water. 

 Some may have died on account of inundation, others doubtless 

 were eaten by the beavers, still others disappeared because of 

 the fact that they were in the route of the beaver operations 

 and were tramped on or uprooted to become part of the con- 

 structing material. 



The shrubs found above the dam in the empounded water 

 were Alnus incana, most of which were thrifty; one very small 

 dead plant of Lonicera canadensis; three patches of Taxus 

 canadensis, of which two were dead and a third, altho but a 

 trifle submerged, was dying; and a very small dying plant of 

 Viburnum cassinoides.
