The Ailanthus-tree for Wood Pidp. By W. H. Taylor. New Zea- 

 land Journal of Agriculture, vol. 18, p. 223. April, 1919. 



Comment is made on an article by Y. Fedele on the suitability of ailan- 

 thus {A. glandulosa) for wood pulp, in a recent issue of the "Monthly 

 Bulletin of Agricultural Intelligence and Plant Diseases," published at 

 Rome. This tree, commonly known as the "tree of heaven," has many 

 qualities which fit it for pulp production. It is readily propagated by 

 root cuttings and transplants well at any age. The growth is rapid, 

 and it has the remarkable habit of making its strongest growth after 

 pollarding. It is said that an acre of trees will yield approximately 25 

 tons of wood every third year. It thrives very well on every site in 

 New Zealand, even on arid or purely rocky soils. The wood yields 44 

 per cent of easily bleached cellulose from which paper pulp can be 

 made. Altogether it is considered a tree of great promise for the paper 

 industrv. E. R. H.
