WOODS AND PLANTATIONS. 437 



at first, being inclined to become bushy for the first few years, but 

 afterwards it grows much faster until it attains a fair height. 



In a recent visit to France I inspected a forest of pinasters on 

 the coast south from Boulogne. The plants were apparently about 

 thirty years old, and were at the time on an average from sixteen to 

 eighteen feet high. They were in a very healthy state, and seemingly 

 making more progress now than they did the first seven or eight years 

 of their growth. The soil they were growing upon was a pure sand, 

 and the subsoil the same, and quite porous. The sand is so light that 

 on the day of my visit quantities of it were driven about by the breeze 

 blowing inland from the sea. This shows the value of the tree for 

 planting on our coasts. It does not succeed on very high-lying and 

 exposed situations so well at least I have not found it to thrive so 

 well there as on the coast-line. I 'have planted it extensively on hills 

 in the midland and northern counties of England, and although a fair 

 proportion of the plants have got away, yet there have been a good 

 number of deaths, and the plants remaining have not succeeded so well 

 as others planted on the coast-line. 



Pinus Pinea (Stone Pine, Linnaeus). This tree is indigenous to the 

 south of Europe, where it grows to a height of from sixty to seventy 

 feet, and forms a large flat head of branches. The leaves are about six 

 inches long, and of a dark-green colour. Some years ago I procured 

 a quantity of the seed of this tree from the north of Italy, which has 

 grown well. The plants are planted on a light loam soil, and are 

 making fair progress. 



Pinus ponderosa (Heavy-wooded Pine, Douglas). This is a native of 

 North America, especially to the north-west of the continent. The tree 

 has a thin and bare appearance from there being few branches on it. 

 It grows to a height of one hundred feet. It is a hardy pine, and 

 is likely to become a useful timber-tree in this country. It is called 

 the heavy-wooded pine, as the timber is said to be so heavy that it 

 will sink in water. I have observed that the best specimens of this 

 tree grow in this country on a light loam soil. 



Pinus Pumilo (Mountain Pine). This is a very useful tree for grow- 

 ing on dry bleak situations. It has been found to succeed well on the 

 chalk wolds of south-eastern Yorkshire and in the southern counties. 

 It does not grow to any great height, attaining only about twenty or 

 thirty feet even in the best situations. 



Pinus Sabiniana (Sabin'sPine, Douglas). This is from the Cordilleras 

 of New Albion, where it grows at an elevation of about one thousand 

 five hundred feet below the line of perpetual snow, and there it attains 

 a height of one hundred feet. The foliage is of a pale-green colour, and
