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
