Periodical Literature. 275 



Kubelka urges the opening up of the forest resources by es- 

 tablishing means of communication, the return to natural methods 

 of regeneration and freedom from the repression of the Period 

 Method of regulating the yield. 



The first chapter deals with the influences of logging methods 

 on forest organization and on methods of management. Kubelka 

 demands the complete opening up of the forest to its uttermost 

 accessibility, if losses in quantity and quality are to be prevented ; 

 that this can best be done by steam logging devices, the neces- 

 sarily greater investment being covered by prevented loss through 

 deterioration and if necessary, by heavier cutting in the overma- 

 ture timber. Only where a complete system of transportation has 

 been installed can the annual cut be properly determined and dis- 

 tributed. (How true of American conditions!) 



The second chapter takes up the tasks of forest organization. 

 Kubelka would confine the forest organizer to determination of 

 the yield 2 or 3 decades in advance, leaving the distribution of 

 the yield — i. e- the choice of cutting areas — to the administrative 

 officer in charge of the forest, in order that the regeneration may 

 proceed according to the silvicultural needs of the stand. 



The Application of Silvicultural Systems, Chapters IV and V, 

 is perhaps the most interesting part of the book. Kubelka claims 

 that the strip selection system* is the one best adapted to the 

 peculiar exigencies of high mountains. This system departs from 

 Wagner's "border cuttings"* primarily in the greater width of 

 the cutting strip. Kubelka justifies this departure because of the 

 increased logging cost on steep slopes. Kubelka is fundamentally 

 opposed to clear cutting and shelterwood cutting over large areas. 

 In the strip selection system which he recommends, the strips 

 run obliquely across the slope, each strip has a maximum width 

 of about 50 yards. When regeneration is well under way, there 

 are three strips side by side — the outermost (earliest) is in state 

 of final removal cutting, the next in that of freeing the reproduc- 

 tion according to its needs, and the third (innermost and latest) 

 in seed cutting. (From the description the system is evidently 

 neither true selection nor true shelterwood, but on the borderland 

 between the two: shelterwood — selection or "Femel.") 



This method results in an unevenaged, mixed stand which has
