In addition to the above, Fraxinvs excelsior, Almis glv.tinosa, Populus 

 serolina, and Acer Pseudo-platanvs occur as planted trees of ten to twenty 

 years' growth. 



The occurrence of the native species is chiefly confined to four patches 

 of broad-leaved scrub, occupying less than five acres altogether. The position 

 of these patches is inchoated on the map (Plate I), and it will be seen that 

 all are on the south-east side of the island, with higher ground to the north 

 and west. A photograph of the best-developed of these patches (near 

 Portlea) is reproduced in Part 10 ; it consists of about two acres of fairly 

 thick scrub of "Willow, Mountain Ash, Hazel, Holly, Oak, and Birch, with 

 a growth of Brambles, Bracken, Honeysuckle, and shade plants beneath. 

 This patch lies from 50 to 100 feet above sea-level, and occupies a slope 

 facing north-east, the soil being fairly deep and good, although inclined to be 

 wet. The tree showing the best development is Birch, which occasionally 

 reaches a height of 10 feet. Hazel also makes a good growth, while Holly 

 develops into a thick bush seldom more than 5 to 6 feet in height. Willow, 

 chiefly Salix aurita, is the most frequent species everywhere, but, from 

 constant cutting, seldom attains its normal height, and the same may be said of 

 Hazel. Oak forms a spreading stool clump about 6 feet in height, and is only 

 sparsely represented in this patch. Another patch occupies a steep slope to 

 the north-west of Lough Avullin, with the same aspect as the first, but has 

 been more heavily grazed by cattle. It consists of Willow, Holly, and Birch,
