Report on Australian and New Zealand Plants groivn 

 on the East Coast of Arran. By the Eev. D. 

 Landsbokough, Kilmarnock. 



(Read Xovember 13, 1884.) 



The island of Arran enjoys a climate in which the 

 severity of winter is as little felt as in any part of Britain. 

 The east coast is specially mild, as here cold frosty winds 

 are tempered by crossing the sea, while their force is 

 destroyed by the high mountains of the Goatfell range 

 rising immediately from the coast to a height of 2866 

 feet, which so lift up the wind, that trees along the coast, 

 instead of being scourged, actually in full luxuriance over- 

 hang the sea at high tide. I have therefore confined the 

 experiments which I have been kindly permitted to make, 

 to this side of the island. The measurements were taken 

 in the beginning of August, and unless otherwise men- 

 tioned, were made 5 feet from the ground. 



Gum Trees. — The first place is due to the Gums, as 

 these are the loftiest trees in the world. Fortunately my 

 list includes two of the most notable species — the Blue 

 Gum, growing to the height of 830 feet, and famous for 

 its sanitary properties : and the Almond-leaved Gum, 

 which grows in Australia to the height of 430 feet. 



EucaJyptus globulus (Blue Gum), at Lamlash. — Girth, 

 1 foot Ih iaches ; height, about 30 feet. Another at 

 Strabane, Brodick, was planted this spring. 



Eucalyptus amygdalina, Corrie, (Almond-leaved Gum), 

 25 feet high, 11 inches in girth. 



Eucalyptus coriocea (White Gum), Lamlash. — The 

 seed of this tree was received in the spring of 1879. 

 The tree is now 14 feet 6^ inches in height, with a girth 

 of 4| inches.
