5. Glen in Calluna area along stream above Killahee, 1250 feet. 

 Pyrus Aucuparia (as fairly Cnicus palustris. 



Galium saxatile. 



As mentioned before, trees must have coyered a wider area in this 

 district in former times, remains of Scots Pine and of Birch being 

 found embedded in peat at 1250 and 1700 feet, respectively. 



As mentioned above, the detailed observations made in actually 

 carrying on this ecological survey were sketched in the field on the 

 Ordnance Survey maps on the scale of six inches to the mile. The 

 accompanying map is a composite one, consisting of portions of Sheets 

 111, 112, 120, and 121 of the one-inch to the mile Ordnance map. 

 The boundaries of our associations were reduced from the six-inch 

 scale to the one-inch, and drawn on the composite map, and were sub- 

 sequently coloured. The index of colours in the margin of the map 

 will supply the information necessary for the recognition of the various 

 associations.
