- THE LONGEVITY OF TREES. 79 
as well as the copyrights of his other works, were pledged to 
the publishers for payment. It is gratifying to learn, that, 
since the writer’s decease, an appeal has been made to the 
public in England, and with great success, to purchase copies 
of this work and of the other publications of Mr. Loudon, so 
that the copyright may be redeemed, and their future pro- 
ceeds applied to the benefit of his surviving family. The 
subjects of landscape-gardening and arboriculture are attract- 
ing increased attention in the United States, and these valu- 
able treatises are not yet so generally known as they deserve 
to be; we have thought it proper, therefore, to make this 
statement. 
While systematically treating of the botanical character, 
propagation, management, and economical uses of trees, Mr. 
Loudon has interwoven a vast amount of curious matter re- 
specting their history, geography, and literature. Being him- 
self a distinguished landscape-gardener, he has successfully 
treated of their character and adaptation as component parts 
of general scenery, of which they form a most important ele- 
ment; for no other constituents — no lifeless objects — pro-

trees. He has also collected interesting statistics respecting 
the longevity of trees; a subject upon which we intend to 
task the patience of our readers to some extent. 
The most interesting ideas connected with trees are those 
suggested by their stability and duration. They far outlast 
all other living things, and form the familiar and appropriate 
symbols of long-protracted existence. ‘“ As the days of a tree 
shall be the days of my people” is one of the most beautiful 
and striking figures under which a blessing can be conveyed. 
We are naturally led to inquire, whether there is any abso- 
lute limit to their existence. If not destroyed by accident, — 
that is, by extrinsic causes, of whatever sort,— do trees 
eventually perish, like ourselves, from old age? It is com- 
monly thought, no doubt, that trees are fully exposed to the 
inevitable fate of all other living things. The opposite 
opinion seems to involve a paradox, and to be contradicted 
by every one’s observation. But popular opinion is an unsafe
