6 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. 



growth ; diflferent to its luxuriant growth in the wetter parts of 

 South Africa. 



Cupressus Lawsoniana. At 20 years of age the best trees 

 average 7 inches diameter and 33 feet high : mean 6 inches by 30 

 feet ; an excellent-looking growth, but with a tendency to bifurcate. 

 Is being tried as a forest tree : the Belgian Government has 

 several trial plots of this species in the forest of Hertogenvald. 

 It is said to do best in Belgium in damp situations. 



Cupressus Nutkaensis. Does not average half the growth of 

 C. Lawsoniana. 



Thujopsis dolabrata. Again only about half of the last species : 

 a failure as a forest tree. 



Thuja occidentalis. Poor growth. 



Acer rubrufn. At 15 years, stem 15 feet high only. The fine 

 autumn tints are now (September 24th) in full show. It is worth 

 planting for its autumn tints. 



Cupressus pisif era. A handsome tree ; but at 19 years shows 

 but a poor growth. Like other Japanese trees the growth in 

 Belgium is uncertain. 



Cryptomeria japonica. Of no use in Belgium (Comte Visart 

 et Bommer) as a forest tree, but those here look fairly well. 

 All the Japanese trees are liable to suffer from drought in 

 Belgium. At 20 years the growth here is only 18 feet high. In 

 1880 many of the Cryptomerias in Belgium were killed by frost. 



Acer platanoides var. purpurea. This shows some good 

 colouring now. 



Sequoia sempervirens. One poor specimen here out of ten 

 planted, and this is one of the few in Belgium, says M. Drion. 

 It will scarcely grow at all out of doors in Belgium. I presume 

 the South of England marks the extreme limit of its climatic 

 habitat on the cold damp soil. 



Sequoia gigantea. Looks well here. It grows well in various 

 places in Belgium where sheltered from the east wind, says 

 M. Drion. There are some fine samples of this tree in Belgium. 



Cedrus Deodara. Good young trees. All the old trees in 

 Belgium, says M. Drion, perished in the severe winter of 1880. 

 They are now planting them again in Belgium. Those here 

 look quite well. 



Liriodendro7i tulipifera. Looks well here and does well 

 enough generally in Belgium, says M. Drion ; to be tried as a 

 forest tree.
