loose, sandy soil which once formed the bed of 
the ocean. Corsican pine also thrives well on 
much the same classes of land, and can very ad- 
vantageously be grown, either by itself or along 
with Scots, in central and southern England, 
though it is less likely to thrive so vigorously in 
the colder climate of the north of Scotland. In 
warm localities it outgrows our indigenous pine 
both in height and girth; and as its timber is at 
least as good as Scots, this greater yield entitles 
it to receive favourable consideration in woods 
grown for profit. In mixed plantations on loamy 
and clayey soils in the Severn Valley it far out- 
strips Scots and is even outgrowing the larch 
planted along with it. On the Earl of Selborne’s 
estate of Blackmoor, in Hants, a few Corsican 
mixed with Scots in the Wolmer plantation, 
formed on deep sandy soil belonging to the 
lower greensand formation, show considerable 
superiority in rate of growth. This crop con- 
sists mostly of Scots pine at north end planted, 
in 1869, somewhat irregularly in lines at 4 to 6 
feet apart. It is now just forming normal canopy, 
but a tangle of bracken covers most of the 
ground. The growth in height is from about 30
