Protection against pasturing and fire is afforded by walling in 

 plantations with loose stone walls and ditches, as well as having 

 guards.

Heavy thinning late in the life of stands for 



Growing the production of large diameters has been 



Stout studied by Dr. Wimmenauer in Hesse for 



Wood. the three species there grown, oak, pine, 



and beech. These studies reveal a favorable 



response to such treatment by each of these species, the increment 



per cent rising with the diameter. 



For oak the very largest trees should be left excepting only 

 those of markedly inferior form. No attempt to preserve a sup- 

 pressed growth should be made. An understory of beech or bass- 

 wood introduced at the proper time is a better practice. The 

 best rotation for growing oak for saw timber is 150 to 160 years, 

 and such rotations yield about 2^ per cent on the investment. 



Pine forests should be thinned with less regard for diameter 

 than for form of boles. A rotation of 120 years gives best results 

 in saw timber. 



Beech is to be handled in much the same way as oak, but great- 

 er attention must be paid to the form of the bole. The heavy 

 thinning should not be deferred beyond the hundredth year in 

 beech stands.

Farming. Under certain conditions it still flourishes 



being employed to advantage for instance in 



the sandy plain south of Darmstadt. 



The forests of the Eberstadt revier cover some five thousand 

 acres in the heart of this region. The annual cut comprises about 

 forty acres. The wood is removed in winter and the ground lies 

 fallow until the following November when it is thoroughly grub- 

 bed over. One-year pine seedlings are set out in the early spring
