Australia, Tasmania, New Zealand, and South Africa. After a 
brief description of some of the principal features of native 
vegetation he deals more exhaustively with the growth of trees 
introduced from the northern hemisphere. The most important 
introduced trees appear to be Conifers, of which Pinus radiata, 
P. Pinaster and P. canariensis are of great promise in many 
places, while other species are locally successful. In South 
Africa various Mexican Pines are giving good results as are 
several species of Cupressus. In Australasia Cupressus macro- 
carpa grows excellently whilst various species of Cedrus and 
Larix are a success in selected areas. Species of Picea, Abies and 
Tsuga appear to be unsatisfactory. Extraordinary results have 
been obtained in Australia, New Zealand and South Africa by 
planting Pinus radiata (P. insignis) under forest conditions. 
A grove felled during Mr. Wilson’s visit in 1921 was planted 
40 years earlier on St. Leonard’s Farm, near Hammer Springs, 
Canterbury, New Zealand. The trees were from 100 to 115 ft. 
in height by 11 to 15 ft. in girth, they averaged 800 board ft. 
of timber and some of the larger ones yielded 1000 board ft. In 
South Africa he was shown trees at the forest station at Tokai 
which were 33 years old, 138 ft. tall and 10 ft. in girth. Two 
stands had been felled at 29 years of age and yielded respectively 
7972 and 7721 cubic ft. of timber per acre. At 40 years of age 
a fully-stocked wood. of this pine is estimated to yield from 
10,000 to 12,000 cubic ft. of timber per acre. The timber 
produced in the southern hemisphere is stated to be superior to 
that produced in its native country, California. Introduced 
hardwood trees appear to be less satisfactory in each country 
than Conifers, although various species of Quercus succeed in 
South Africa.
