These plants occurred in a layer of peaty sand. Small stems 

 and twigs were not uncommon, and all belonged to the genera 

 Be tula and Salix, lu most cases these stems Avere decorticated, 

 and bore evidence of drifting. Most of the seeds and fruits in the 

 list were quite uninjured, but the character of the layer and the 

 assemblage of plants indicate that they were drifted by water to 

 the place where they are now found. 



Several small pieces of charcoal 5 to 10 mm. square were also 

 found in the general collection, but the carbonization may possibly 

 be due to causes other than fire. A considerable portion of the 

 material consisted of the leaves of Salix lierhacea, felted together in 

 lenticular masses. 



In addition to the plants enumerated in the above list, the 

 washings contained many small petal-like objects. These have 

 not been identified, but they are certainly not the petals of 

 Dry as, JRuhus chain cemor us, or Parnassia palustris. Several small 

 brownish flakes were present : these consisted of much-compressed 

 fragments of epidermis and other plant-debris, felted together. The
