PREFACE 



The following work appeared originally in 

 German in the "Austrian Forestry Magazine," 

 and in view of the increased interest taken in 

 forestry in England an English translation may 

 perhaps be acceptable in this country. 



The writer's object is to present in the most 

 concise manner the results of numerous experi- 

 ments, chiefly made in Germany, with some 

 American trees, most of which are known as 

 ornamental specimens, but have not received 

 due attention in forest plantations here. A 

 great deal of misapprehension exists as to their 

 value, and as Germany has done most of the 

 experimental forest-tree planting, it is instructive 

 to hear the consensus of opinion of that country.
