Government Botanist, Queensland. I sowed at once. 

 Xext year, when only 9 inches in height, one of the seed- 

 lings was planted at Craigard, Lamlash. The following 

 winter was very severe, — zero at the West End Gardens, 

 Glasgow, and probably down to 21° at Craigard, yet not a 

 leaf was browned. In 1886 it was 21 feet in height 

 and 9h inches in girth, having grown at the yearly rate of 

 3^ feet in height and 2h inches in girth. Lest it should 

 be blown over it has been twice more or less polled, yet it 

 has continued to increase in girth by 2 inches yearly. It 

 blooms and bears seed every year. Its seed has germi- 

 nated at the Edinburgh Eoyal Botanic Garden. Uninjured 

 last year. It is named White Gum from the whiteness 

 of its bark, specially when the old bark is newly shed ; 

 Weeping Gum from its habit ; Swamp Gum from the soil 

 in which it is often seen. It grows in Australia to the 

 height of about 150 feet. 



YIII. Eucalyptus cordata (Silver Gum). 



1. Craigard, Lamlash. Planted 1889. Height, 8 feet; 

 girth, 5f inches. Much injured; yet some leaves fresh, 

 even on the top branch. Has not bloomed. 



2. Cromla, Corrie. Planted 1895. Height, 3 feet 

 7 inches. 



3. Lochhournhead. "A tree planted out in 189'4 when 

 two years old was very slightly cut by winter of 1894—5, 

 is now about 6 feet high, and growing fast." — Birkbeck. 



This is a dwarf gum growing to a maximum height 

 of 50 feet ; but in poor soil it often remains shrubby, 

 blooming and ripening seed when not more than three 

 feet in height. In this state it is the most dwarf of 

 all gums, except E. vernicosa." — Mueller. In Arran, 

 owing to the abundant moisture, the tendency to shrubbi- 

 ness has not shown itself. The species is remarkable 

 when young for the silvery bloom upon its leaves, 

 specially in dry weather in summer, rain washing it off. 

 The odour of its leaves is very similar to that of the 

 Blue Gum {E. globulus) and almost as powerful. It has 

 not as yet bloomed in Arran. 



IX. Eucalyptus rudis (Slender Gum). 



Cromla, Corrie. Planted 1887. Height, 14 feet (to
