3. Prolonged soaking in cold water 

 does not reduce the strength of green 

 wood below that of its fiber saturation 

 point, provided it remains in perfect 

 condition. When wood has been dried 

 and is re-soaked it becomes slightly 

 weaker than when green. 



4. Wood soaked in heated water ab- 

 sorbs more moisture because the 

 amount of water which the fiber will 

 contain is increased. This causes a 

 reduction in strength and stiffness, as 

 in wood that is heated or steamed for 

 bending. 



THE FORESTRY EDUCATION BILL 



Measure of Wide Importance Now Before 



Congress Should Be Passed At This Session 



BY 

 SAMUEL B. GREEN 



Professor of Forestry, University of Minnesota 



DERHAPS the most important 

 piece of new forestry legisla- 

 tion on which Congress will be asked 

 to pass at its next session is the bill 

 (H. R. 10,100) introduced by Con- 

 gressman Davis of Minnesota, which 

 provides funds for the support of a 

 chair of forestry in each of the agri- 

 cultural colleges and for experimental 

 forestry work in each of the experi- 

 ment stations of all the states and ter- 

 ritories. This bill was introduced in 

 the last session and has not attracted 

 the attention that is due to it. There 

 can be no question but what the best 

 way of educating the people to the 

 importance of forestry and forestry 

 matters is through some measure of 

 this kind that will make a center of in- 

 telligent forestry ideas in every state. 

 If one will note the great advance in 

 agricultural science, due to appropria- 

 tions for a similar purpose and ex- 

 pended in a similar way, I think he 

 can get an idea of the possibilities of 

 such legislation for the encouragement 

 of forestry. 



The subject of forestry has attracted 

 much attention during the last few 

 years, and the help of President Roose- 

 velt has been of the greatest assist- 

 ance to the movement, as his words 

 in regard to it have been quoted 

 widely. As a result of this a large 

 number of bright young men are look- 

 ing for opportunities in this line and 

 it would seem as if for the welfare of 

 the whole country, as well as of the 

 several states it is important that they 

 be furnished with the training they 

 so much desire. 



The bill in question is so drawn as 

 to require the appropriation it carries 

 to be used entirely for work in for- 

 estry. There is not a state or territory 

 in the Union but what is greatly in 

 need of the assistance that would be 

 rendered by the passage of this bill. 

 It is to be hoped that the friends of 

 forestry will rally to the support of 

 this measure and push it through Con- 

 gress the coming winter.
