and porcina, Juglans nigra, Quercus rubra, and Magnolia hypo- 

 leuca. Qf only limited value are Betula lutea, Fraxinus ameri- 

 cana, and Prunus serotina, and for their esthetic value only our 

 maples, although Acer saccharum is considered excellent in cop- 

 pice with standards and selection forest. 



Tables showing in detail forest conditions and measurements 

 of some 26 areas from 20 to 30 years old are given, in which 

 some II different species or combinations are shown. Of these 

 perhaps of most interest is the large volume increment for the 

 third decade in Pseudotsuga, namely from 320 to 388 cubic feet 

 of workwood (over 3 inch) per acre. 



The figures for the best stand show in the 27th year 499 trees 

 with an average diameter of 7 inch and height of 53 feet, a vol- 

 ume of workwood of 753 cubic feet, the thinnings having re- 

 moved 454 trees with 345 cubic feet, the average increment dur- 

 ing the last 5 years being 382 cubic feet of workwood. (See 

 experiences in Hesse, p. 490 of this volume!)

Burkhardt breaks a lance for this rare and 



Plantations usually unconsidered species. Citing the 



of literature of the species he gives a brief 



Taxus life history of its development. It reaches 



haccata. a height of over 60 feet, and diameters of 



over 4 feet are on record. An account of 



various trial plantations is given, and on account of its excellent 



wood for special uses its occasional employment is recommended.
