forest land or agriculture land, but which may be devoted to 

 either purpose according to local conditions. 



Mr. Zon discusses the problem of meeting the timber supply in 

 the future on a basis of 150,000,000 population. He makes an 

 interesting comparison with other countries where one may con- 

 clude that in order not to disturb the natural balance the pro- 

 portions of the forest land to other kinds of land must be not 

 less than from one-fifth to one-third of the total area of the 

 country. Countries with about 100 acres per 100 inhabitants 

 produce more wood than they actually consume, while countries 

 with 85 or less per 100 people produce less wood than their con- 

 sumption. The conclusion is that there must be an area of about 

 180 acres of forest land for every 100 inhabitants if a country is 

 to be sustained. But in this country the per capita consumption 

 is much larger than in Europe, so that at the present rate of use 

 the United States would soon be unable to supply the demand 

 from its own resources. In as much as it will not be possible to 

 import a great deal of timber from abroad it is obvious that the 

 rate of consumption must decrease and also the rate of produc- 

 tion increase. In case our per capita use should be reduced from 

 the 260 cubic feet which it is now, to 150 feet and if the annual 

 growth of our forests were increased to 50 cubic feet, the 450,- 

 000,000 acres which it is estimated will comprise the forests of 

 50 years hence the demands of the people may be met. 



These are a few of the more important conclusions. The paper 

 is an exceedingly interesting one and should be read by everyone 

 interested in the problem of conservation.

Instructions for Reforesting Land. By C. R. Pettis. State 

 of New York, Forest, Fish and Game Commission. Albany, 

 N. Y., 1909. Pp. 22. Plates 18. 



In this pamphlet Mr. Pettis sets forth some definite, concise 

 instructions regarding the establising of forests by planting in the 

 State of New York. The directions given relate to how best to 

 secure stock for planting, what to plant, when to plant, where to 

 plant and how to plant. A brief discussion of the financial re- 

 sults of planting is also presented.
