1009. Brewster, Donald R. A plan for the advancement of forestry in Wisconsin. 

 Jour. Forestry 18: 792-802. 1920. — The area of cut-over land in Wisconsin amounts to about 

 three million acres. Much of this land is now idle and unproductive. The ordinary organi- 

 zation of the State Board of Forestry is not thought advisable and a conservation council is 

 proposed consisting of small groups of men chosen from each congressional district. The 

 financial support would be derived from contributions from interested parties or from assess- 

 ments upon organizations. The principal lines of work of this council would be the preven- 

 tion and control of fires, the expansion of state forests, the reform of tax laws, survey of 

 timber resources, and the establishment of experiment stations to work out forest problems. 

 — E. N . Munns. 



1010. Brewster, Donald R. A plan for combined insurance and fire protection. Jour. 

 Forestry 18: 803-805. 1920. — A plan is outlined to make forest protection and insurance auto- 

 matic and self-supporting, and at the same time increase the area of timber lands under 

 forest management. All forest lands would be assessed a small amount per acre to cover the 

 cost of this protection and insurance, with exemption to wood lots and isolated areas. 

 Brush lands would be considered of sufficient value to warrant protection and insurance 

 until they were placed in a productive position. The advantages claimed are that the prop- 

 erty owner would feel he was getting protection as well as insurance, and the distribution of 

 risk, if combined with the tax reform, would make the production of timber a safer and more 

 attractive investment for the private owner. — E. N . Munns.

 value in France for forest planting, together with a description of the sites and places where 

 such trees would do best. — E. N . Munns.
