894 RESULTS OF FOREST PLANTATION. 
But the modern improved methods of sylviculture show 
vastly more favorable financial results; and when we consider 
the immense collateral advantages derived from the presence 
of the forest, the terrible evils necessarily resulting from its de- 
struction, we cannot but admit that the preservation of existing 
woods, and the more costly extension and creation of them 
where they have been unduly reduced or have never existed, 
are among the plainest dictates of self-interest and most ob- 
vious of the duties which this age owes to those that are to 
come after it. 
Financial Results of Forest Plantation. 
Upon the whole, I am persuaded that the financial statistics 
which are found in French and German authors, as the results 
of European experience in forest economy, present the ques- 
tion under a too unfavorable aspect ; and therefore these calcu- 
lations ought not to discourage landed proprietors from making 
experiments on this subject. These statistics apply to woods 
whose present condition is, in an eminent degree, the effect of 
previous long-continued mismanagement; and there is much 
reason to believe that in the propitious climate of the United 
States new plantations, regulated substantially according to the 
methods of De Courval, Chambrelent, and Chevandier, and ac- 
companied with the introduction of exotic trees, as, for example, 
the Australian caruarina and eucalyptus*—which latter, it is 
sake of the bark and the young twigs used by tanners. In England, trees are 
grown at the rate of two thousand to the acre, and cut for props in the mines 
at the diameter of a few inches. Plantations for hoop-poles, and other special 
purposes requiring small timber, would, no doubt, often prove highly remu- 
nerative. 
* Although the eucalyptus thrives admirably in Algeria—where it attains 
a height of from fifty to sixty feet, and a diameter of fifteen or sixteen inches, 
in six years from the seed—and in some restricted localities in Southern 
Europe, it will not bear the winters even of Florence, and consequently can- 
not be expected to flourish in any part of the United States except the ex- 
treme South and California. The writer of a somewhat enthusiastic article 
en this latter State, in Harper’s Monthly for July, 1872, affirms that he saw a
