Australian and New Zealand Trees iji Arran* By Rev. D,

(Read 11th November 1886.) 



The island of Arran is the most northern locality where 

 Australian and New Zealand trees and shrubs have been 

 extensively cultivated. The success which has attended the 

 experiment has attracted much notice; Baron von Miiller, in 

 his most valuable work on the Eucalypts of Australia, and also 

 in his Select Extra- Tropical Plants, makes constant reference 

 to them. This has led the writer to give this year a more 

 detailed account than has yet appeared.t 



Arran, situated between 55|° to 55f ° N. lat., 20 miles in 

 length by 8 or 10 miles in breadth, is one of the Inner 

 Hebrides, and lies at the mouth of the Clyde. The northern 

 half is mountainous, ascending to the height of 2866 feet; 

 the southern half is much more level, ascending to only half 

 the height of the northern. The rainfall varies much, but 

 everywhere it is great ; at Lamlash it averages 66 inches. 

 There is, however, little mist or fog along the coast, where 

 all the trees are planted, and there are few days some part 

 of which is not dry. The temperature in winter is much 

 higher than on the mainland. On the lighthouse at Pladda, 

 half a mile south of Arran, at the height of 110 feet, the 

 lowest temperature for thirty years was in January 1881, 

 when it sunk to 28° F. The temperature is moderated by 

 its insular position, by the Gulf Stream, and by the fact 

 that channels of deep water (averaging about 450 feet in 

 depth) run lengthways near to the shore along both sides of 

 Arran. 



Many of the trees mentioned grow in the garden of 

 Captain Brown at Lamlash. His house is in the middle of 

 the Bay of Lamlash. The bay is 3 miles in length, and is 

 protected by the Holy Isle, lying in the centre of the bay, 

 at 1*38 miles from the shore and 1030 feet in height, while 

 the mountains behind Lamlash also ascend to the height of 

 1003 feet. The trees are planted in a good soil, abounding 



* The measurements, unless mentioned, are taken at 5 feet from the ground. 

 When trees are not from Australia or New Zealand this is stated.
