MOLLUSCAN INVESTIGATION IN WEST ROSS 57 



a small mill in the wood, a work which has to all appearance 

 been going on some time. Some of the woodland consists 

 of pine and larch only, but of no great age. Some parts of 

 the slopes higher up Kerrysdale have been planted in this 

 manner. There are numerous marshy or boggy patches of 

 ground, both in the woods and on the slopes of the shore, 

 the predominating plants being iris, meadowsweet, several 

 kinds of rushes, several umbellifers, nettles, bracken, etc. 

 The investigation of this area was done on the 30th and 31st 

 July 1910.
