Forestry Education. — In addition to the forestry section at 

 the Norwegian Agricultural High School, which has a three- 

 year course, the State supports two elementary schools of 

 forestry at a cost of about ,£1,100, The course lasts one year, 

 and the number of pupils averages forty-eight; instruction 

 is free. 



There are likewise three county schools of forestry, the 

 expenses of which are paid by the counties in question, but 

 which also receive a grant from the State. 



The State has also instituted several nurseries, which 

 furnish the plants required for the State forests and supply 

 private landowners with plants. Several seed farms have 

 been laid out by the State, whence the seed is derived for the 

 use of the State and for sale to private persons. 



The Norwegian Forestry Association. — In 1898 the Nor- 

 wegian Forestry Association was privately formed for the 

 furtherance of forestry. This Association has been strongly 

 supported and has branches in all the counties. The State grant 

 to the Society amounts at present to ^6,256, this sum being 

 used mainly in assisting private owners of forests to sow and 

 plant trees and to drain swampy forest land. The grant from 

 the State is paid out through the branch offices, which must 

 procure a similar amount from the Local Councils or from 

 private persons, as a contribution towards the cost of the 

 work that is to be carried out. By the publication of a 

 monthly Journal, and by issuing pamphlets from time to 

 time, the Association endeavours to promote knowledge 

 regarding the proper management of forests.
