PERIODICAL LITERATURE 657 



The last installment (to date) is an enthusiastic description of 

 Tubeuf's trip from Denver over "^loffatt Road'' to the Arapaho 

 Forest, where he saw the lodgepole pine in its glory. The young stands 

 on old burns, he says, "simply clamor for thinnings. But who is there 

 to do it ? The ranger has no control over the choppers ; he does not 

 direct the cutting. The sale of the wood is on the stump, to a dealer 

 who uses the best material and leaves the rest. Nature does the re- 

 seeding. This is the usual sequence and is the chief difference from 

 German forest management." A. R. R.
