hence useful in ship and dock building, are commercially exploited. 

 The distribution of these species leads to the recognition of seven 

 forest types and the construction of a map, locating the same, about 

 one third of the total forest area being occupied by types containing 

 the above species. 



The Parana pine forest region, which is being exploited, is lo- 

 cated in the southeastern portion of Brazil, cutting sometimes as 

 much as 20 M feet to the acre. The Antarctic beech region, which 

 contains the Chilian pine, also some larch and cedar, is located 

 along water courses in Western Patagonia, on the slopes of the 

 Andes. 



The hardwoods, in which quebracho forms the commercially 

 important species, are found chiefly in northern Argentina with an 

 estimated area of 84 million acres and a stand of 168 million tons. 



Greenheart, with mora, is located in the river forests of British 

 Guina over a range of 154 million acres. 



The mahogany region is located, with 54 million acres, along the 

 northwest coast, and finally the tropical and subtropical hard- 

 woods, with 1200 biUion acres, occupying the largest area, are 

 occupying the Amazon watershed, the balance being non-forested 

 or brush areas. 



In 1912, the export of forest products, including copaiva, tolu 

 and quillaya bark, amounted to $9,282,625, while the importation 

 of wood and manufacture amotmted to aroimd 32 million dollars. 



In spite of the vast extent of the forest area the author says: 

 "not only quebracho, but many other valuable species of trees with 

 which the forests abound are in danger of extinction (when their 

 use has been found out?) in the not very distant future as the 

 result of inadequate forestry laws." 



To find out the character and uses of the many hardwood species 

 with a view to export is a primary task; the softwoods are so 

 limited as to reqmre reservation for home consimiption.
