between 60 ft. and 70 ft. high, although the soil 
on which they grow is scarcely 2 inches thick, on a 
bed of solid chalk. About the same time, from 60 
to 70 plants were planted at White Knights, by 
the Duke of Marlborough, in good loamy soil, 20 
or 30 of which still exist, and are from 50ft. to 60ft. 
high ; but, being crowded in a wood of indigenous 
and other free-growing trees, they have not assumed 
handsome shapes ; and, indeed, there are only 
branches on their upper extremities.” 
In addition to the trees here mentioned, it 
appears that two are growing in the Glasnevin 
Botanic Garden, Dublin, which were planted in 
1797, and are upwards of fifty feet high. They 
were not identified till 1834, when they bore cones ; 
these proved exactly alike, although the habit of 
the trees is very dissimilar, the one being irregu- 
larly spreading, whilst the other, as mentioned by 
Mr. Niven, assumes an elegant, cyi^ress-like form. 
Young trees, of this variety of Pinus, have 
hitherto been expensive, on account of our nur- 
serymen being dependent on foreign seeds ; for 
although cones have been freely produced on some 
of the trees that exist in this country, still their 
seeds have not ripened. Mr. Lambert mentions 
it as especially adapted to thin chalky soils, and 
maritime districts. As an ornamental tree, it is 
very desirable ; its wood, however, although very 
durable, from its resinous knotty nature, is less 
valuable than that of many other species. Its 
resin has a pleasant fragrance, and, it is said, is 
frequently used as the chief ingredient of incense, 
in Boman Catholic churches.
