concludes that a short period of subaerial erosion intervened 

 before the deposition of the marine clay, on the Waterville esker. 

 In the course of Professor Little's work a large marine fauna 

 was collected from the clay at Waterville as well as occasional 

 leaves of the vegetation then growing on the nearby shores, 

 and it is the purpose of the present brief note to record the plants 

 discovered in these clays and their evidence regarding the late 

 Pleistocene history of the region. 



The determinable species represented are the following: 

 Populiis halsamifera Linne (two incomplete specimens). 

 Ilex verticillata (Linne) A. Gray (one well-preserved specimen 

 shown in Fig. 3). 



Fig. I. (i), Gaylussacia dumosa; (2), Vaccinium corymhosum; (3), Ilex verticil- 

 lata, all from marine clays of Maine. 



Gaylussacia dumosa (Andr.) T. and G. (the specimen shown in 



Fig. i). 

 Vaccinium corymbosum Linne (four specimens, one of which is 



shown twice natural size in Fig. 2). 

 Populus halsamifera is found in the existing flora from Labrador 

 to Maine, New York and Michigan, northward to Hudson Bay 

 and northwestward to British Columbia and Alaska. It is
