(1) Till or slope podzol 



(2) Outwash or well-drained valley bottom podzol 



2. Intrazonal soils 



a. Half-bog 



b. Bog 



c. Alpine meadow 



d. Brown forest 



3. Azonal soils 



a. Lithosol 



b. Alluvial 



A detailed description of physical and chemical properties of important 

 soils should contribute to an understanding of the silvical requirements 

 of forest stands. Accordingly, an attempt is being made to obtain re- 

 presentative samples of all of the following soils: 



Till or slope podzol 



CXitwash or well-drained valley bottom podzol 



Half-bog 



Brown forest 



Lithosol 



Sampling has been completed for two slope podzols, two valley bottom pod- 

 zols, two half-bog, and one lithosol profile. Laboratory analyses are 

 partly completed for these samples. Field work and laboratory analyses 

 are expected to continue during 1958. 



A New Quick Cruise Method 



Foresters have always been interested in methods for determining stand 

 volumes quickly and with consistent accuracy. Rapid techniques are 

 usually employed for such problems as determining the merchantability 

 or timber type of a stand where these features are defined by volume. 

 The old method of ocular estimation, based upon extensive experience, 

 meets with less favor in the modern day of confidence limits and the 

 determination of sampling error.
