ment, especially of Calamagrostis ; the young spruce disliking 

 shade above (although liking side shade) — these conditions must 

 occasion endless difficulties to a natural regeneration. 



Yet the author would advise at least a trial of Wagner's selec- 

 tion strip method. As to Wagner's declaration that the spruce 

 is not a good transplanter, the author calls attention that 100 

 years' experience in Saxony has proved the contrary.

We suppose that our readers realize, that 

 Ultra whether they express their ideas of the 



Conservative maturity of a tree or stand in diameter 

 Rotations. sizes or values, they consciously or uncon- 



sciously discuss the time element in forest 

 production — the rotation. 



A lively and exceedingly important and interesting debate has 

 lately taken place in the Bavarian Legislature, and in consequence 

 in the daily press of Bavaria and elsewhere, as regards the pro- 

 priety of reducing the existing rotations in the Bavarian State 

 forests. 



Of the nearly 2,000,000 acres, timber forest (91.4% of total 

 forest area) of which 20% are oak and beech, 50% spruce and 

 fir, 30% pine, a rotation of 96 years (the Bavarians follow a duo- 

 decimal system) is found on 22%, while the balance is over 108 

 years ; indeed, beech, fir and spruce seem to be managed in a 

 rotation of 140 years. Hence the old age classes, over 100 years, 

 occupy over 20% of the area, as against a normal 16.7%. In de- 

 manding a reduction of these supposedly excessively conservative 

 rotations it was pointed out that with 57 cubic foot per acre the 

 felling budget falls behind the yield of Saxony, Baden and Wurt- 

 temberg, who work with lower rotations, by 15 to 24 cubic feet; 

 that the result of thinnings, too, with only 15 cubic feet per acre 

 was too low; that the net yield in Bavaria with $2.68 per acre 

 compared unfavorably with Saxony and Wurttemberg whose ad- 

 ministrations yield $5 and $5.60 respectively, that the work wood 

 per cent, in Bavaria with about 64% was lower probably because 

 of the frequent red rot in the old spruces ; that in the market, trees 

 of 10 to 14 inch diameter, which can be attained in spruce with 

 rotations of 70 to 100 years, are more sought than stouter material.
