586 Forestry Qttarterly. 



Astounded at the discrepancies between 

 Valuation estimate and cut of stands, even where all 



Siirveys. the trees have been calipered, Krebs, a 



young working plans officer, tries to hit 

 upon a more practical method than calipering to determine the 

 volume of somewhat abnormal stands. The common practice 

 in German Forest organization in such stands is to caliper all 

 the stems at breast height (1.3 meters) and then to calculate the 

 basal area. This the author considers unreliable and suggests 

 as a substitute stand-yield tables based on results of actual fell- 

 ings with emphasis on a painstaking description of stand and 

 soil. That is, the yield of a given stand is taken to be the same 

 as that of the one which the description shows to be strictly 

 analogous. 



Wimmenauer, mellowed by nearly 50 years of practical ex- 

 perience, tones down the above by commenting that, perhaps, 

 the discrepancies of cut and estimate are due in large measure 

 to inaccuracies in measuring the timber after it has been cut, as 

 well as in making the estimate; that stand-yield tables are no 

 doubt valuable, but require such exhaustive data that calipering 

 is quicker and simpler. A. B, R.

We have before noted the remarkable 

 Prices prices secured for the old oak timber for 



fo7' which the Spessart mountains are cele- 



Heavy brated. In the winter of 1912-1913 sev- 



Oak. eral 400 year old oaks were sold at public 



auction. The timber was divided into 

 nine quality classes according to diameter, soundness, and fine- 

 ness of grain. 51.18% consisted of saw timber, 12.17% cord- 

 wood, and 36.65% small fuelwood. The prices varied within 

 42% for the best ; the highest price paid being $3.43 per cubic 

 foot or $360 per M. bd. ft. (!) assuming for such large sized 

 logs 9 board feet per cubic foot. 



On account of the steadily advancing price of oak in the 

 Spessart region the holding over for several rotations of selected 

 individuals has proved financially profitable. The following
