Barthon develops in an interesting manner 



Selection the impropriety of applying the usual selec- 



Strip tion method to a stand of spruce with a 135- 



Method year rotation, as was done. The objection 



in is based on an enumeration of the trees by 



France. diameter, age and increment, which shows 



that the trees of smaller diameter are by no 



means younger, but merely poorer trees, which have only hindered 



the development of their neighbors without being able to produce 



much themselves. 



Under such conditions to take out the largest and leave the 

 smaller diameters, conserving the runts of poor increment and 

 incapable of growing with good dimensions, means a selection of 

 the wrong kind. According to the author such stands at low 

 altitudes (2,500 feet) should be treated by the group method, the 

 openings to be approximately the square of one and one-half the 

 height of the stand ; larger on north exposures, smaller on south 

 sides, and smaller in open stands exposed to the light. 



In higher altitudes, where the regeneration is hindered by the 

 snow, two or more fellings for reproduction are needed : the first 

 felling consists in thinning severely a strip, leaving the stoutest 

 and most wind resistant trees ; by the second cut a new strip is 

 thinned and the whole stand on the first strip is removed. [Wag- 

 ner's selection strip method!] If necessary, the regeneration is 

 completed by planting. Meanwhile the rest of the forest is thin- 

 ned by removal of dead and dying, always for the benefit of the 

 vigorous trees. 



An appeal for more extended studies of the composition from 

 this point of view of selection forest is made.
