acre and also to mature timber which is increasing in yield or value per acre

Close forest utilization with a portable mill, E. A. Ziegler {Forestry 

 Quart., 13 {1915), J\'o, 4, pp. 4^5-467). — This comprises an accurate record of

The present forest tax situation in New Hampshire, J. H. Fostee {Forestry 

 Quart., 13 {1915), No. 4, pp. 474-480). — A comparative study of 126 distinct 

 and widely scattered timber lots, mostly second growth white pine, with ref- 

 erence to tax assessments and timber conditions in 1908 as compared with 

 assessments and timber conditions in 1914. 



The author concludes, in part, that an assessed valuation in excess of 50 per 

 cent of the actual values on poorly-gi'owing lots or in excess of 75 per cent on 

 good-growing lots will generally cause a loss to the owner unless he cuts the 

 timber at once and will always cause a loss to the town if he does cut. Abrupt 

 increases in taxation cause the owner to cut his timber regardless of his 

 financial advantage.
